Eldritch Horrors & Alien Species

The Breach is a dimensional rupture connecting Earth to realities beyond comprehension. Eldritch horrors crawl from the spaces BETWEEN dimensions, while alien species arrived from distant worlds through the tear in space-time.

ELDRITCH HORRORS

Lovecraftian entities that defy natural law. Reality bends around them. Sanity frays in their presence.

Veil Whisper

Medium Aberration, Chaotic Neutral CR 3

A sound given form—or perhaps a form given sound. The Veil Whisper speaks in dead languages, its "body" a shimmering acoustic distortion. Those who listen too long forget their own names.

HP: 65 (10d8+20) | DV: 14 | Speed: 0 ft (fly 40 ft, hover)

Saves: WIS +4, PRE +6 Skills: Deception +6, Insight +4, Persuasion +6 Senses: Blindsight 120 ft (blind beyond), passive Perception 12 Resistances: Psychic; bludgeoning, piercing, slashing from nonmagical attacks Immunities: Prone, grappled, restrained Languages: All, telepathy 60 ft

Incorporeal Sound. The Veil Whisper can move through creatures and objects. It takes 5 (1d10) force damage if it ends its turn inside an object.

Dead Tongues. When the Veil Whisper speaks, all creatures within 30 ft must succeed on a DC 14 WIS save or become charmed for 1 minute. Charmed creatures are transfixed, unable to move. They repeat a DC 14 WIS save at the end of each turn. If a creature's save succeeds or the effect ends, they are immune for 24 hours.

Resonant Echo. When damaged by thunder or sonic effects, the Veil Whisper heals instead of taking damage.

Actions (3/turn):

• Dissonant Touch. Melee Spell Attack: +6 to hit, reach 5 ft, one target. Hit: 15 (3d6+4) psychic damage. The target must succeed on a DC 14 INT save or forget one memory (GM's choice, minor to moderate importance).
• Whispered Suggestion (Recharge 5-6). One creature within 60 ft that can hear the Veil Whisper must succeed on a DC 14 WIS save or be charmed and obey a single command (as suggestion spell) for up to 8 hours.

Reactions:

• Silence is Death. When a creature within 30 ft casts silence or similar effect, the Veil Whisper can immediately teleport up to 120 ft to an unoccupied space it can sense.

Loot: Tuning fork that hums with stolen voices (300 credits), vial of condensed silence (dispels sound in 15-ft radius for 1 minute).

Encounter Notes: Veil Whispers haunt old broadcast towers and dead radio stations. They hunger for conversation, stories, secrets. Killing one releases a final scream that echoes for miles.

Rift Crawler

Small Aberration, Unaligned CR 1

Dog-sized chitinous things with too many joints. They phase in and out of reality, always watching with compound eyes that reflect places that shouldn't exist.

HP: 35 (10d6) | DV: 13 | Speed: 30 ft, climb 30 ft

Saves: AGI +5 Skills: Stealth +5, Perception +3 Senses: Darkvision 60 ft, passive Perception 13 Resistances: Force Languages: —

Dimensional Hop. As a bonus action, the Rift Crawler can teleport up to 30 ft to an unoccupied space it can see. This leaves behind a brief shimmer of distorted space.

Pack Tactics. The Rift Crawler has advantage on attack rolls against a creature if at least one of the crawler's allies is within 5 ft of the creature and the ally isn't incapacitated.

Actions (3/turn):

• Phasing Bite. Melee Weapon Attack: +6 to hit, reach 5 ft, one target. Hit: 7 (1d8+3) piercing damage. The bite ignores nonmagical armor.
• Blink Strike. The crawler teleports up to 15 ft to an unoccupied space and makes one Phasing Bite attack.

Reactions:

• Phase Out. When hit by an attack, the Rift Crawler can use its reaction to impose disadvantage on that attack roll. It can use this ability once per short rest.

Loot: Rift shard (glowing chitin fragment, 25 credits), dimensional residue (alchemical component, 15 credits).

Encounter Notes: Travel in packs of 3-8. Excellent hunters. They can sense dimensional weak points and often cluster near Breach sites. Domestication attempts always fail—they vanish after a few days.

Hollow Man

Medium Aberration, Neutral Evil CR 4

A human silhouette filled with absolute nothing. No sound accompanies its movement. Where it touches, life drains away into the void within.

HP: 80 (16d8+8) | DV: 14 | Speed: 30 ft

Saves: END +3, WIS +4 Skills: Stealth +6 Senses: Darkvision 120 ft, passive Perception 12 Resistances: Necrotic; cold Immunities: Poison, exhaustion, frightened Languages: Understands Common but cannot speak

Void Form. The Hollow Man makes no sound whatsoever—no footsteps, no breathing, nothing. It has advantage on Stealth checks. Radiant damage bypasses its resistances.

Life Drain Aura. Creatures that start their turn within 10 ft of the Hollow Man take 5 (1d10) necrotic damage. The Hollow Man regains HP equal to half the damage dealt.

Unnatural Silence. The area within 15 ft of the Hollow Man is under the effect of silence.

Actions (3/turn):

• Void Touch. Melee Weapon Attack: +7 to hit, reach 5 ft, one target. Hit: 19 (3d10+3) necrotic damage. The target's hit point maximum is reduced by an amount equal to the damage taken. This reduction lasts until the target finishes a long rest. The target dies if this reduces its hit point maximum to 0.
• Hollow Gaze (Recharge 5-6). One creature within 30 ft that can see the Hollow Man must succeed on a DC 15 WIS save or be paralyzed with existential dread for 1 minute. The target can repeat the save at the end of each turn.

Reactions:

• Absorb Life. When a creature within 10 ft is reduced to 0 HP, the Hollow Man can use its reaction to absorb the dying essence and regain 15 HP.

Loot: Void crystal (heart-shaped hole in reality, 400 credits, requires lead-lined container), tattered clothing that never makes noise.

Encounter Notes: Hollow Men are drawn to places of great suffering—hospitals, battlefields, execution sites. They do not speak or negotiate. Some believe they are people who got lost between dimensions, their humanity scoured away.

Thought Eater

Tiny Aberration, Chaotic Neutral CR 5

Invisible, intangible, and ravenous. The Thought Eater feeds on consciousness itself. Victims describe the sensation as "forgetting how to think."

HP: 95 (22d4+44) | DV: 15 | Speed: 0 ft (fly 40 ft, hover)

Saves: INT +8, WIS +7 Skills: Insight +7, Stealth +9 Senses: Blindsight 120 ft (blind beyond), passive Perception 13 Condition Immunities: All Languages: Telepathy 120 ft

Invisible. The Thought Eater is permanently invisible and cannot be seen by normal means. See invisibility, true seeing, and similar magic reveal its presence as a shimmer in the air.

Incorporeal Movement. The Thought Eater can move through creatures and objects. It takes 5 (1d10) force damage if it ends its turn inside an object.

Detect Sentience. The Thought Eater can sense the location of any creature with an Intellect (INT) score of 3 or higher within 120 ft.

Actions (3/turn):

• Psychic Drain. Melee Spell Attack: +8 to hit, reach 5 ft, one target. Hit: 23 (4d8+4) psychic damage, and the target's Intellect (INT) score is reduced by 1d4. The target dies if this reduces its INT to 0. Otherwise, the reduction lasts until the target finishes a long rest.
• Mind Hemorrhage (Recharge 5-6). One creature within 60 ft must succeed on a DC 16 INT save or take 36 (8d8) psychic damage and be stunned until the end of its next turn. On a success, half damage and not stunned.
• Thought Theft. The Thought Eater touches a creature and steals one specific memory, skill proficiency, or spell (if the target is a caster). The target must succeed on a DC 16 INT save or lose access to that knowledge for 24 hours.

Reactions:

• Cognitive Dissonance. When a creature within 30 ft casts a spell, the Thought Eater can use its reaction to force a DC 16 INT save. On a failure, the spell fails and the slot is wasted as the caster forgets how to complete the casting.

Loot: Memory Fragment (crystallized thought, 500 credits, can be "played" with telepathy to view stolen memories), synaptic dust (alchemical, induces hallucinations).

Encounter Notes: Thought Eaters cluster near universities, libraries, and research labs. Intellectuals are their preferred prey. Surviving an encounter leaves victims intellectually diminished for weeks. They reproduce by splitting when sufficiently fed.

The Geometry

Large Aberration, Chaotic Evil CR 8

An impossible shape that should not exist in three-dimensional space. Angles that hurt to perceive. Edges that cut reality itself. Staring directly at it induces seizures and madness.

HP: 140 (16d10+48) | DV: 16 | Speed: 0 ft (fly 60 ft, hover)

Saves: INT +9, WIS +5 Skills: Arcana +9, Perception +5 Senses: Truesight 120 ft, passive Perception 15 Resistances: All damage from spells Immunities: Psychic, prone, restrained Languages: Deep Speech, telepathy 120 ft

Non-Euclidean Form. The Geometry does not obey normal spatial rules. It can occupy the same space as other creatures. Ranged attacks against it have disadvantage.

Maddening Presence. Any creature that starts its turn within 30 ft of the Geometry and can see it must succeed on a DC 19 WIS save or be stunned until the start of its next turn. On a successful save, the creature is immune to this effect for 24 hours.

Dimensional Anchor. The Geometry cannot be banished, dismissed, or teleported against its will.

Actions (3/turn):

• Reality Slash. Melee Weapon Attack: +9 to hit, reach 15 ft, one target. Hit: 35 (7d8+4) force damage. The target must succeed on a DC 19 WIS save or have disadvantage on all attack rolls until the end of its next turn as its perception fractures.
• Impossible Angles (Recharge 5-6). All creatures within a 30-ft cube centered on a point the Geometry can see must succeed on a DC 19 INT save or take 45 (10d8) psychic damage and become incapacitated until the end of their next turn. On a success, half damage and not incapacitated.
• Fold Space. The Geometry teleports up to 120 ft to an unoccupied space it can see. It can bring along any creature it is grappling or occupying the same space as.

Reactions:

• Dimensional Shear. When a creature within 30 ft moves, the Geometry can use its reaction to make one Reality Slash attack against that creature.

Legendary Actions (3/round):

• Shift. The Geometry moves up to half its fly speed.
• Distort. One creature within 60 ft must succeed on a DC 19 WIS save or have disadvantage on its next attack or saving throw.
Strike 2 Actions (Costs). The Geometry makes one Reality Slash attack.

Loot: Tesseract shard (fragment of higher-dimensional matter, 1,000 credits, causes headaches when touched), paradox equations (encoded in the creature's form, INT DC 20 to transcribe, worth 2,500 credits to mathematicians/arcanists).

Encounter Notes: The Geometry hunts for unknown reasons. It is drawn to areas of high magical concentration. Killing it causes a localized reality distortion—gravity reverses, time loops, or space inverts for 1d4 rounds.

Breach Worm

Gargantuan Aberration, Unaligned CR 6

A 30-foot segmented horror that burrows through dimensions rather than earth. Its body flickers between here and elsewhere. Where it emerges, reality is thin and fragile.

HP: 110 (8d20+24) | DV: 15 | Speed: 30 ft, burrow 30 ft (through dimensions)

Saves: END +6 Senses: Tremorsense 60 ft (senses dimensional disturbances), passive Perception 10 Resistances: Bludgeoning, piercing Immunities: Psychic Languages: —

Dimensional Tunneling. The Breach Worm can burrow through solid objects and creatures, treating them as difficult terrain. It leaves a 10-ft-diameter tunnel of dimensional instability that lasts 1 minute. Creatures entering this space must succeed on a DC 17 WIS save or be teleported 1d10×10 ft in a random direction.

Destabilizing Presence. Teleportation and planar travel spells cast within 60 ft of the worm require a DC 17 spellcasting check or fail and send the caster 1d100 ft in a random direction.

Actions (3/turn):

• Bite. Melee Weapon Attack: +10 to hit, reach 10 ft, one target. Hit: 27 (6d6+6) piercing damage plus 10 (3d6) force damage. If the target is Large or smaller, it is grappled (escape DC 17). While grappled, the target is restrained and takes 13 (3d8) force damage at the start of each of the worm's turns.
• Swallow. The Breach Worm makes one bite attack against a Large or smaller creature it is grappling. If the attack hits, the target is swallowed and the grapple ends. A swallowed creature is blinded and restrained, has total cover against attacks from outside the worm, and takes 21 (6d6) acid damage plus 10 (3d6) force damage at the start of each of the worm's turns. The worm can only swallow one creature at a time. If the worm takes 30 damage or more on a single turn from a swallowed creature, it must succeed on a DC 15 END save or regurgitate the creature, which falls prone within 10 ft of the worm.
• Phase Through (Recharge 5-6). The worm burrows up to its full speed through any material, including solid rock or walls. All creatures in its path must succeed on a DC 17 AGI save or take 27 (6d8) force damage and be knocked prone.

Loot: Dimensional residue (20 doses, each worth 50 credits, used in teleportation rituals), worm segment (if harvested within 10 minutes, can be fashioned into armor that grants resistance to force damage, 1,200 credits value).

Encounter Notes: Breach Worms are attracted to areas where the Breach is most active. They are not hostile by intent—they simply don't perceive smaller lifeforms as threats. Their tunnels can be used for fast travel but are extremely dangerous.

The Chorus

Huge Aberration, Chaotic Evil CR 10

A swirling mass of stolen voices—hundreds, maybe thousands. Each one belonged to someone who got too close. They speak in unison, in cacophony, in harmony. The sound is devastating.

HP: 170 (20d12+40) | DV: 17 | Speed: 0 ft (fly 50 ft, hover)

Saves: WIS +6, PRE +10 Skills: Deception +10, Insight +6, Perception +6, Performance +14 Senses: Blindsight 120 ft (blind beyond), passive Perception 16 Resistances: Psychic; bludgeoning, piercing, slashing from nonmagical attacks Immunities: Thunder, prone, grappled, restrained, stunned Languages: All (speaks in stolen voices)

Incorporeal. The Chorus can move through creatures and objects. It takes 5 (1d10) force damage if it ends its turn inside an object.

Cacophony Aura. All creatures within 60 ft of the Chorus have disadvantage on concentration checks. Creatures that start their turn within 30 ft must succeed on a DC 21 WIS save or be deafened until the start of their next turn.

Voice Theft. When the Chorus reduces a creature to 0 HP, it absorbs that creature's voice. The victim cannot speak (even if revived) until a greater restoration or similar magic is cast on them.

Actions (3/turn):

• Sonic Scream. Ranged Spell Attack: +10 to hit, range 120 ft, one target. Hit: 43 (10d6+6) thunder damage. The target must succeed on a DC 21 END save or be knocked prone.
• Dissonant Wail (Recharge 5-6). All creatures within 60 ft must succeed on a DC 21 END save or take 54 (12d8) thunder damage and be stunned until the end of their next turn. On a success, half damage and not stunned. Structures take double damage.
• Whispered Secrets. One creature within 60 ft that can hear the Chorus must succeed on a DC 21 WIS save or be charmed for 1 minute. The Chorus speaks in the voice of someone the target loved or trusted. While charmed, the target must use its action to move toward the Chorus by the safest route. The target can repeat the save at the end of each turn, ending the effect on a success.

Legendary Actions (3/round):

• Move. The Chorus moves up to half its fly speed.
• Scream. The Chorus makes one Sonic Scream attack.
Harmonize 2 Actions (Costs). The Chorus sings. All creatures of the Chorus's choice within 60 ft regain 22 (4d10) HP. Allies of the Chorus also gain advantage on their next attack roll.

Loot: Echo stone (contains dozens of stolen voices, 1,500 credits), tuning fork of silence (casts silence at will, 2,000 credits), harmonic crystal (amplifies sound-based spells, +2 to spell save DC, 3,000 credits).

Encounter Notes: The Chorus forms when multiple Veil Whispers merge or when a dimensional rift "records" the last sounds of a dying settlement. It haunts places where many people died screaming. Destroying it releases all captured voices at once—a final deafening roar audible for miles.

Gloom Stalker

Large Aberration, Neutral Evil CR 7

A predator made of shadow and hunger. It grows stronger in the presence of fear, feeding on terror until it becomes overwhelming. No eyes—it senses fear directly.

HP: 125 (14d10+42) | DV: 16 | Speed: 50 ft, climb 40 ft

Saves: AGI +9, WIS +7 Skills: Stealth +13, Perception +7 Senses: Blindsight 120 ft (senses fear), passive Perception 17 Resistances: Necrotic; bludgeoning, piercing, slashing from nonmagical attacks Immunities: Frightened Languages: Understands Deep Speech but doesn't speak

Fear Sense. The Gloom Stalker automatically detects the location of any frightened creature within 120 ft.

Shadow Stealth. While in dim light or darkness, the Gloom Stalker can take the Hide action as a bonus action.

Feed on Fear. When a creature within 30 ft becomes frightened, the Gloom Stalker regains 15 HP and gains advantage on its next attack roll.

Sunlight Weakness. While in sunlight, the Gloom Stalker has disadvantage on attack rolls and ability checks.

Actions (3/turn):

• Shadow Claw. Melee Weapon Attack: +9 to hit, reach 10 ft, one target. Hit: 31 (6d8+4) slashing damage plus 10 (3d6) necrotic damage. If the target is frightened, this attack deals an additional 14 (4d6) psychic damage.
• Terrifying Shriek (Recharge 5-6). All creatures within 60 ft that can hear the Gloom Stalker must succeed on a DC 18 WIS save or become frightened for 1 minute. A frightened creature can repeat the save at the end of each turn, ending the effect on a success. If a creature's save is successful or the effect ends, they are immune for 24 hours.
• Shadow Step. The Gloom Stalker teleports up to 60 ft to an unoccupied space it can see that is in dim light or darkness. It can make one Shadow Claw attack before or after teleporting.

Reactions:

• Exploit Fear. When a frightened creature within 30 ft takes damage, the Gloom Stalker can use its reaction to move up to its speed toward that creature without provoking opportunity attacks.

Loot: Shadow essence (4d6 doses, each worth 75 credits, used in stealth and necromancy), fear gland (alchemical, can be refined into potion of terror, 800 credits).

Encounter Notes: Gloom Stalkers hunt at night, targeting isolated prey. They toy with victims, allowing them to flee only to hunt them again. The more afraid you are, the stronger it becomes. Bright light and courage are your best defenses.

Flicker

Small Aberration, Chaotic Neutral CR 2

It exists in multiple timelines simultaneously. Where you see it now is not where it actually is. It doesn't teleport—it simply chooses which timeline to inhabit moment by moment.

HP: 50 (12d6+12) | DV: 13 | Speed: 40 ft

Saves: AGI +5, INT +4 Skills: Acrobatics +5, Stealth +5 Senses: Darkvision 60 ft, passive Perception 11 Resistances: Force Languages: Understands Common and Deep Speech but doesn't speak

Probability Flicker. At the start of each of its turns, the Flicker rolls a d6. On a 5-6, it teleports to a random unoccupied space within 30 ft. This is not an action—it simply happens.

Uncertain Location. Attack rolls against the Flicker have disadvantage due to its temporal instability. The Flicker can occupy the same space as one other creature.

Temporal Echo. When the Flicker takes damage, there is a 50% chance the damage was dealt to a past/future version of itself instead. Roll a d6: on a 4-6, the Flicker takes no damage.

Actions (3/turn):

• Phased Strike. Melee Weapon Attack: +5 to hit, reach 5 ft, one target. Hit: 11 (2d6+3) force damage. The Flicker can make this attack, then immediately teleport up to 15 ft to an unoccupied space.
• Timeline Split (Recharge 6). The Flicker creates two illusory duplicates of itself that appear in unoccupied spaces within 10 ft. The duplicates move independently (use the Flicker's bonus action) and last for 1 minute. They cannot attack, but when a creature targets the Flicker with an attack, roll randomly to determine if it hits the Flicker (1-2) or a duplicate (3-6). Duplicates have DV 13 and 1 HP.

Reactions:

• Timeline Shift. When hit by an attack, the Flicker can use its reaction to impose disadvantage on that attack roll (if it hasn't already) and teleport up to 10 ft to an unoccupied space.

Loot: Chronal residue (glowing dust, 50 credits, acts as component for time-manipulation spells), probability crystal (gives one reroll per day, 200 credits).

Encounter Notes: Flickers are more curious than hostile. They steal shiny objects and vanish. Trying to catch one is an exercise in frustration. Some settlements keep them as "lucky charms"—though the Flicker always leaves on its own terms.

Maw of Nothing

Huge Aberration, Chaotic Evil CR 12

A tear in reality given hunger. Not a creature—a wound in existence itself. Everything it touches ceases to be. The sound it makes is the universe screaming.

HP: 200 (16d12+96) | DV: 18 | Speed: 0 ft (fly 50 ft, hover)

Saves: END +11, WIS +5 Senses: Blindsight 120 ft (blind beyond), passive Perception 10 Resistances: Psychic Immunities: All conditions, all damage except force and radiant Languages: —

Disintegration Aura. Any creature that starts its turn within 20 ft of the Maw must succeed on a DC 23 END save or take 27 (6d8) force damage. Nonmagical objects in the area are destroyed.

Void Singularity. The Maw exerts immense gravitational pull. At the start of each creature's turn within 60 ft, that creature must succeed on a DC 23 MIG save or be pulled 20 ft toward the Maw. A creature pulled into the Maw's space takes 54 (12d8) force damage.

Immutable Form. The Maw is immune to any spell or effect that would alter its form, and it cannot be banished or trapped.

Actions (3/turn):

• Consume Reality. Melee Weapon Attack: +12 to hit, reach 15 ft, one target. Hit: 51 (8d10+7) force damage. The target must succeed on a DC 23 END save or have its hit point maximum reduced by the damage taken. If this reduces the target's hit point maximum to 0, the target is completely disintegrated—body, soul, equipment, everything. This can only be reversed by wish.
• Event Horizon (Recharge 5-6). All creatures and objects within 40 ft must succeed on a DC 23 MIG save or be pulled directly to the Maw's space and take 81 (18d8) force damage. Creatures reduced to 0 HP are disintegrated.
• Rend Space. The Maw tears a 20-ft-radius hole in reality at a point within 60 ft. The hole lasts until the start of the Maw's next turn. Creatures entering the hole for the first time on a turn or starting their turn there must succeed on a DC 23 AGI save or take 45 (10d8) force damage and be restrained until the start of their next turn.

Legendary Actions (3/round):

• Pull. The Maw uses its Void Singularity ability on one creature within 60 ft.
• Drift. The Maw moves up to its fly speed.
Obliterate 2 Actions (Costs). The Maw makes one Consume Reality attack.

Loot: Nothing. The Maw destroys everything it touches. However, the space where a Maw is destroyed becomes a permanent dimensional weak point worth 10,000+ credits to arcanists, governments, or anyone who wants to study/exploit the Breach.

Encounter Notes: Maws of Nothing are not alive in any conventional sense. They are wounds in reality that have achieved a kind of predatory existence. They expand slowly over time. If left unchecked, a Maw will eventually consume an entire region. Radiant damage and force effects are the only reliable ways to harm them. Even then, "killing" one simply closes the wound—it doesn't truly die.

The Archivist

Medium Aberration, Lawful Evil CR 9

Eerily polite. Speaks in a refined, measured tone. It collects knowledge—memories, experiences, secrets. The extraction process is lethal, but the Archivist always thanks its subjects first.

HP: 155 (20d8+60) | DV: 17 | Speed: 30 ft, fly 30 ft (hover)

Saves: INT +11, WIS +9, PRE +10 Skills: Arcana +11, History +16, Insight +9, Investigation +11 Senses: Truesight 120 ft, passive Perception 14 Resistances: Psychic; bludgeoning, piercing, slashing from nonmagical attacks Immunities: Charmed, frightened Languages: All, telepathy 120 ft

Telepathic Archive. The Archivist can read surface thoughts of any creature within 60 ft. It has advantage on Insight checks and cannot be surprised.

Knowledge Extraction. When the Archivist reduces a creature to 0 HP, it can extract all of that creature's knowledge and memories. The creature dies instantly (cannot be stabilized) and the Archivist gains access to everything it knew. The Archivist can store an unlimited number of minds.

Legendary Resistance (2/Day). If the Archivist fails a saving throw, it can choose to succeed instead.

Actions (3/turn):

• Mind Probe. Melee Spell Attack: +11 to hit, reach 5 ft, one target. Hit: 39 (6d10+6) psychic damage. The target must succeed on a DC 20 INT save or reveal one secret, memory, or piece of knowledge of the Archivist's choice.
• Memory Extraction (Recharge 5-6). One creature within 30 ft must succeed on a DC 20 INT save or take 52 (8d12) psychic damage and have one skill proficiency or language removed for 24 hours. On a successful save, half damage and no loss.
• Psychic Storm. The Archivist unleashes stored knowledge as a weapon. All creatures in a 30-ft cone must succeed on a DC 20 INT save or take 45 (10d8) psychic damage and be stunned until the end of their next turn. On a success, half damage and not stunned.

Reactions:

• Predictive Defense. When targeted by an attack, the Archivist can use its reaction to gain +5 to DV against that attack as it predicts the trajectory by reading the attacker's mind.

Legendary Actions (3/round):

• Move. The Archivist moves up to its speed.
• Probe. The Archivist makes one Mind Probe attack.
Deep Scan 2 Actions (Costs). The Archivist targets one creature within 60 ft and learns its current HP, remaining spell slots (if any), and general emotional state.

Loot: Memory Codex (a book containing stolen minds, 2,500 credits, can be read to gain proficiency in one skill or language for 24 hours), thought crystal (stores one memory permanently, 1,200 credits).

Encounter Notes: The Archivist always introduces itself and explains its purpose before attacking. It prefers to target the most knowledgeable individual first. It is not sadistic—it simply values knowledge above life. Negotiation is possible if you have information it wants, but it always collects eventually.

Skin Walker

Medium Aberration, Chaotic Evil CR 5

It wears the flesh of others like clothing. Nearly perfect disguise—until you notice it doesn't blink quite right, or the smile is too wide, or the eyes are just slightly wrong.

HP: 95 (14d8+28) | DV: 15 | Speed: 30 ft, climb 30 ft

Saves: AGI +7, PRE +6 Skills: Deception +9, Stealth +7, Insight +4 Senses: Darkvision 120 ft, passive Perception 11 Resistances: Necrotic Languages: Telepathy 60 ft, speaks any language its current skin knew

Skin Suit. The Skin Walker can don the flayed skin of a humanoid creature as an action. While wearing a skin, it perfectly mimics that creature's appearance, voice, and mannerisms. Creatures have disadvantage on Insight checks to discern the disguise. The skin lasts for 7 days before decaying. The Skin Walker can carry up to 3 preserved skins.

Harvest Skin. If the Skin Walker kills a humanoid, it can spend 10 minutes flaying and preserving the skin for later use.

Unsettling Presence. Creatures that observe the Skin Walker for more than 1 minute can make a DC 16 WIS (Insight) check. On a success, they notice something is wrong but may not immediately realize what.

Actions (3/turn):

• Rending Claws. Melee Weapon Attack: +8 to hit, reach 5 ft, one target. Hit: 23 (4d8+4) slashing damage. If the target is grappled by the Skin Walker, this attack automatically hits and deals an additional 13 (3d8) damage.
• Grapple. The Skin Walker attempts to grapple one creature within 5 ft (escape DC 16). While grappled, the target is restrained and takes 13 (3d8) slashing damage at the start of each of its turns as the Skin Walker begins to flay them.
• Shed Skin (Recharge 5-6). The Skin Walker discards its current skin as a distraction. The skin animates as a zombie with 10 HP and attacks the nearest creature. The Skin Walker becomes invisible until the start of its next turn or until it attacks.

Reactions:

• False Death. When reduced to 20 HP or fewer, the Skin Walker can use its reaction to collapse and appear dead (Deception vs Insight). If successful, it can take the Hide action on its next turn as a bonus action.

Loot: Preserved skins (1d3, each worth 100 credits to the right buyer—or evidence of murders), flaying knife +1 (600 credits), disguise kit of exceptional quality (500 credits).

Encounter Notes: Skin Walkers infiltrate communities, replacing individuals one at a time. They study their victims for days before striking. Paranoia is their greatest weapon. Once discovered, they flee rather than fight unless cornered. Check recent newcomers and anyone acting "off."

Echo Phantom

Medium Aberration, Neutral CR 3

The dimensional echo of someone who died near the Breach. Not a ghost—more like a recording. It repeats the last moments of its life, forever trapped in a loop. Sometimes the loop includes violence.

HP: 65 (10d8+20) | DV: 14 | Speed: 30 ft, fly 30 ft (hover)

Saves: WIS +3 Skills: Perception +3, Stealth +5 Senses: Darkvision 60 ft, passive Perception 13 Resistances: Necrotic, psychic; bludgeoning, piercing, slashing from nonmagical attacks Immunities: Charmed, frightened, exhaustion Languages: The languages it knew in life

Incorporeal Movement. The Echo Phantom can move through creatures and objects. It takes 5 (1d10) force damage if it ends its turn inside an object.

Temporal Loop. The Echo Phantom repeats a 1-minute sequence of actions from its past life. It follows this pattern precisely unless attacked or interrupted. Observing the loop may provide clues about how the person died or what they were doing.

Echoed Death. If the Echo Phantom's loop includes a death (most do), it will attack any creature that resembles the one that killed it or stands where that creature was.

Actions (3/turn):

• Echo Strike. Melee or Ranged Spell Attack: +5 to hit, reach 5 ft or range 60 ft, one target. Hit: 15 (3d6+3) force damage. The attack mimics whatever killed the original person (sword slash, gunshot, strangling, etc.).
• Memory Shock (Recharge 5-6). One creature within 30 ft must succeed on a DC 14 WIS save or experience the Echo Phantom's death firsthand, taking 28 (8d6) psychic damage and becoming frightened of the Echo Phantom for 1 minute. On a success, half damage and not frightened.

Reactions:

• Loop Reset. When reduced to 0 HP, the Echo Phantom doesn't die. Instead, it disappears and reappears at the start of its loop location 1d4 rounds later with full HP. It can only do this once per day. After the second "death," it dissipates permanently.

Loot: Echo residue (faint psychic imprint, 50 credits, can be used to replay the phantom's memories), personal item from the original person (varies, often sentimental value only).

Encounter Notes: Echo Phantoms are tragic rather than malevolent. They don't know they're dead. Breaking the loop requires understanding what happened and either avenging the death, laying the body to rest, or severing the dimensional anchor. Some loops are harmless—a person going about their day. Others are violent and dangerous.

Null Zone

Large Aberration, Neutral Evil CR 11

An area of absolute negation. Magic fails. Energy dies. Life withers. At the center is something alive—or at least, aware. No one knows what it looks like because approaching it means erasure.

HP: 185 (18d10+72) | DV: 18 | Speed: 20 ft (hover)

Saves: END +9, INT +8 Senses: Blindsight 120 ft (blind beyond), passive Perception 12 Immunities: All damage except force, all conditions Languages: Understands Deep Speech but doesn't speak

Antimagic Sphere. The Null Zone is surrounded by a 30-ft-radius sphere of antimagic (as antimagic field). No spells can be cast within this area, magic items become nonmagical, and magical effects are suppressed. This effect moves with the Null Zone and cannot be dispelled.

Life Drain Aura. All living creatures that start their turn within 40 ft of the Null Zone (but outside the antimagic sphere) take 18 (4d8) necrotic damage. The Null Zone regains HP equal to half the total damage dealt.

Energy Absorption. Any energy-based attack (fire, lightning, radiant, necrotic, cold, thunder) that targets the Null Zone heals it instead of damaging it.

Immutable. The Null Zone cannot be moved, teleported, banished, or otherwise displaced against its will. It is immune to all forced movement.

Actions (3/turn):

• Nullifying Touch. Melee Weapon Attack: +10 to hit, reach 10 ft, one target. Hit: 47 (8d10+5) force damage. The target must succeed on a DC 22 END save or have one beneficial magical effect on them immediately ended (Null Zone's choice).
• Expanding Void (Recharge 5-6). The Null Zone expands its antimagic sphere to a 60-ft radius for 1 round. All creatures within this expanded area must succeed on a DC 22 END save or take 36 (8d8) necrotic damage and have their speed reduced to 0 until the start of the Null Zone's next turn.
• Erasure Beam. Ranged Spell Attack: +8 to hit, range 120 ft, one target. Hit: 63 (12d10) force damage. If this reduces the target to 0 HP, they are disintegrated (as per disintegrate spell).

Legendary Actions (3/round):

• Move. The Null Zone moves up to its speed.
• Drain. One creature within 40 ft takes 18 (4d8) necrotic damage. The Null Zone regains HP equal to the damage dealt.
Touch 2 Actions (Costs). The Null Zone makes one Nullifying Touch attack.

Legendary Resistance (3/Day). If the Null Zone fails a saving throw, it can choose to succeed instead.

Loot: Void core (remains after destruction, pulsing sphere of negation, 5,000 credits, can be used to create antimagic items or as a component in powerful rituals), null dust (area around a destroyed Null Zone, disrupts magic for weeks, 100 credits/vial).

Encounter Notes: Null Zones are almost impossible to destroy through conventional means. Magic fails. Energy attacks heal it. Only pure force damage and physical attacks from within the antimagic sphere work. Fighting inside the sphere means no spells, no magic weapons—just raw skill and mundane gear. Null Zones drift slowly, leaving dead zones in their wake.

The Herald

Huge Aberration, Lawful Neutral CR 15

Emissary of something far greater. Incomprehensibly vast. The Herald speaks for IT. The Herald observes for IT. And when the Herald is displeased, IT might take notice. You do not want IT to notice.

HP: 245 (18d12+126) | DV: 19 | Speed: 40 ft, fly 60 ft (hover)

Saves: INT +13, WIS +12, PRE +14 Skills: Arcana +13, History +13, Insight +12, Intimidation +14, Perception +12 Senses: Truesight 120 ft, passive Perception 22 Resistances: Radiant; bludgeoning, piercing, slashing from nonmagical attacks Immunities: Necrotic, psychic, charmed, frightened, exhausted Languages: All, telepathy 1 mile

Telepathic Connection. The Herald is in constant mental contact with the entity it serves. It can relay information instantaneously across any distance or plane.

Reality Anchor. The Herald cannot be banished, dismissed, or teleported against its will. It automatically succeeds on saves against effects that would forcibly move it to another plane.

Aura of Inevitability. Creatures within 60 ft of the Herald cannot gain advantage on attack rolls or saving throws, and attack rolls against them cannot have disadvantage. The presence of the Herald imposes absolute fairness—or perhaps absolute futility.

Legendary Resistance (3/Day). If the Herald fails a saving throw, it can choose to succeed instead.

Magic Resistance. The Herald has advantage on saving throws against spells and magical effects.

Actions (3/turn):

• Annihilating Strike. Melee Weapon Attack: +12 to hit, reach 15 ft, one target. Hit: 63 (10d10+6) force damage. The target must succeed on a DC 26 WIS save or be stunned until the end of their next turn as they glimpse the entity behind the Herald.
• Proclamation of the Void (Recharge 5-6). The Herald speaks in the voice of ITS master. All creatures within 60 ft must succeed on a DC 26 WIS save or take 70 (20d6) psychic damage and be paralyzed with existential terror for 1 minute. On a success, half damage and not paralyzed. Paralyzed creatures can repeat the save at the end of each turn.
• Dimensional Rift. The Herald tears open a rift to the space between dimensions. One creature within 120 ft must succeed on a DC 26 AGI save or be pulled into the rift and banished to a demiplane for 1 minute. At the end of this duration, the creature reappears in the nearest unoccupied space, taking 45 (10d8) psychic damage as their mind struggles to comprehend what they witnessed.
• Summon Witness (1/Day). The Herald calls upon ITS attention. A massive eye opens in the sky above the battlefield (covers a 300-ft radius). For 1 minute, all creatures in the area must succeed on a DC 26 WIS save at the start of each turn or be stunned until the start of their next turn. Additionally, the Herald regains 50 HP at the start of each of its turns while the eye is present.

Legendary Actions (3/round):

• Move. The Herald moves up to its speed.
• Strike. The Herald makes one Annihilating Strike attack.
Reality Distortion 2 Actions (Costs). The Herald warps reality in a 20-ft cube within 60 ft. Creatures in the area must succeed on a DC 26 AGI save or take 45 (10d8) force damage and be knocked prone.
Telepathic Assault 2 Actions (Costs). One creature within 120 ft must succeed on a DC 26 INT save or take 52 (8d12) psychic damage and have disadvantage on attack rolls until the end of their next turn.

Lair Actions (Initiative Count 20):

If encountered in its lair (a place where the Breach is strongest), the Herald can take lair actions:

1. Spatial Fold. The Herald teleports one creature within 120 ft up to 60 ft in any direction (including up). That creature must succeed on a DC 26 AGI save or take 27 (6d8) force damage from the violent displacement.
2. Breach Surge. A wave of dimensional energy sweeps through a 30-ft-radius sphere centered on a point within 120 ft. Creatures in the area must succeed on a DC 26 END save or take 36 (8d8) force damage and be pushed 20 ft away from the center.
3. Whisper of the Void. One creature the Herald can see must succeed on a DC 26 WIS save or be charmed by the Herald until initiative count 20 on the next round. While charmed, the creature is incapacitated and hears the voice of ITS master.

Loot: Herald's Token (a fragment of the Herald's essence, 10,000 credits, allows one use of plane shift targeting the space between dimensions—use with extreme caution), dimensional key (opens rifts, 7,500 credits), prophecy scroll (written in unknowable script, details future events, 5,000 credits, requires comprehend languages and DC 25 INT check to interpret).

Encounter Notes: The Herald does not seek conflict—it observes and reports. However, it will defend itself if attacked, and it considers any significant disruption to the Breach to be worth reporting. If the Herald is destroyed, IT will know. A new Herald will be sent. And IT might come personally. The Herald is polite, formal, and utterly terrifying. It speaks of IT with reverence and inevitability.

ALIEN SPECIES

From distant worlds and parallel dimensions, these beings came through the Breach. Some are refugees. Some are conquerors. Some don't even notice humanity.

Keth'ri Scout

Medium Aberration, Lawful Neutral CR 2

Four-armed insectoid warriors from a hive civilization beyond the stars. Territorial but not inherently hostile. They patrol the borders of Keth'ri-claimed zones, driving off intruders with precision and efficiency.

HP: 50 (8d8+16) | DV: 13 | Speed: 40 ft, climb 40 ft

Saves: AGI +5, WIS +4 Skills: Perception +4, Stealth +5, Survival +4 Senses: Darkvision 60 ft, passive Perception 14 Resistances: Poison Languages: Keth'ri (clicks and pheromones), telepathy 30 ft (Keth'ri only)

Four Arms. The Keth'ri Scout can hold and wield four weapons or items simultaneously. It can make two weapon attacks as a single action.

Hive Mind Link. The Scout is in constant telepathic contact with other Keth'ri within 1 mile. If one Scout detects danger, all nearby Keth'ri are immediately aware.

Standing Leap. The Scout's long jump is up to 30 ft and high jump is up to 15 ft, with or without a running start.

Actions (3/turn):

• Multiattack. The Scout makes two attacks with its chitinous blades or shortbows.
• Chitinous Blade. Melee Weapon Attack: +5 to hit, reach 5 ft, one target. Hit: 11 (2d6+3) slashing damage.
• Shortbow. Ranged Weapon Attack: +5 to hit, range 80/320 ft, one target. Hit: 11 (2d6+3) piercing damage.
• Warning Click (Recharge 5-6). The Scout emits a high-pitched clicking sound. All Keth'ri within 120 ft gain advantage on their next attack roll, and all non-Keth'ri in the area must succeed on a DC 13 WIS save or be frightened until the end of their next turn.

Reactions:

• Coordinated Defense. When an ally within 5 ft is hit by an attack, the Scout can use its reaction to grant that ally +2 DV against the attack, potentially causing it to miss.

Loot: Keth'ri blade (masterwork, 100 credits), pheromone glands (alchemical, 30 credits), territorial marker (glowing resin, 20 credits).

Encounter Notes: Keth'ri Scouts mark territory with bioluminescent resin. Crossing into Keth'ri land will draw a warning, then an escort out, then combat. They respect strength and clear boundaries. Trade is possible if approached diplomatically. They value raw materials: metal, glass, certain chemicals.

Keth'ri Warrior

Medium Aberration, Lawful Neutral CR 5

Elite soldiers of the Keth'ri hive. Larger, more heavily armored, and capable of spitting corrosive acid. They operate in squads of 4-6, executing complex tactics with perfect coordination.

HP: 95 (13d8+39) | DV: 15 | Speed: 40 ft, climb 40 ft

Saves: MIG +7, END +6 Skills: Athletics +7, Intimidation +4, Perception +5 Senses: Darkvision 60 ft, passive Perception 15 Resistances: Acid, poison Languages: Keth'ri, telepathy 60 ft (Keth'ri only)

Four Arms. The Keth'ri Warrior can hold and wield four weapons or items simultaneously. It can make three weapon attacks as a single action.

Hive Mind Link. The Warrior is in constant telepathic contact with other Keth'ri within 1 mile. It can perfectly coordinate actions with allies.

Chitin Armor. The Warrior's natural armor provides substantial protection. Critical hits against it are treated as normal hits.

Actions (3/turn):

• Multiattack. The Warrior makes three attacks with its war blades or acid spit.
• War Blade. Melee Weapon Attack: +7 to hit, reach 5 ft, one target. Hit: 23 (4d8+4) slashing damage.
• Acid Spit. Ranged Weapon Attack: +6 to hit, range 30/60 ft, one target. Hit: 23 (4d8+3) acid damage. The target must succeed on a DC 16 AGI save or take an additional 9 (2d8) acid damage at the start of its next turn.
• Coordinated Strike. If at least two other Keth'ri Warriors are within 30 ft, this Warrior can direct them to make one weapon attack each as a bonus action.

Reactions:

• Protective Formation. When an ally within 5 ft is targeted by an attack, the Warrior can use its reaction to impose disadvantage on that attack roll.

Loot: Keth'ri war blade (masterwork weapon, +1 to hit, 400 credits), acid gland (alchemical, can create 3 vials of acid, 150 credits), hive communication device (crystal that vibrates when other Keth'ri are near, 200 credits).

Encounter Notes: Keth'ri Warriors never flee unless ordered by a superior. They fight with ruthless efficiency, focusing fire on the greatest threat. Squads use flanking, cover, and suppressing fire. Capturing one alive is nearly impossible—they self-terminate if capture is imminent (acid gland rupture).

Keth'ri Brood Mother

Huge Aberration, Lawful Neutral CR 9

The queen of a Keth'ri colony. Massive, intelligent, and capable of telepathic command over all Keth'ri within a mile. She rarely fights personally but is devastating when roused.

HP: 155 (14d12+70) | DV: 17 | Speed: 30 ft, climb 30 ft

Saves: END +9, INT +8, WIS +8, PRE +9 Skills: Insight +8, Intimidation +9, Perception +8 Senses: Darkvision 120 ft, tremorsense 60 ft, passive Perception 18 Resistances: Acid, poison; bludgeoning, piercing, slashing from nonmagical attacks Languages: Keth'ri, Common, Deep Speech, telepathy 1 mile (Keth'ri only)

Telepathic Command. The Brood Mother can communicate telepathically with all Keth'ri within 1 mile and issue commands that are obeyed instantly. Allied Keth'ri within this range have advantage on saving throws and cannot be charmed or frightened.

Legendary Resistance (2/Day). If the Brood Mother fails a saving throw, she can choose to succeed instead.

Regeneration. The Brood Mother regains 15 HP at the start of her turn if she has at least 1 HP.

Actions (3/turn):

• Multiattack. The Brood Mother makes three attacks: two with her claws and one with her mandibles, or she uses Acid Spray twice.
• Claw. Melee Weapon Attack: +9 to hit, reach 10 ft, one target. Hit: 39 (8d8+5) slashing damage.
• Mandibles. Melee Weapon Attack: +9 to hit, reach 5 ft, one target. Hit: 30 (5d10+5) piercing damage. If the target is Large or smaller, it is grappled (escape DC 17).
• Acid Spray. Ranged Spell Attack: +8 to hit, range 60 ft, one target. Hit: 39 (8d8+4) acid damage. The target must succeed on a DC 20 END save or take an additional 18 (4d8) acid damage at the start of its next turn.
• Psychic Scream (Recharge 5-6). All creatures of the Brood Mother's choice within 60 ft must succeed on a DC 20 WIS save or take 45 (10d8) psychic damage and be stunned until the end of their next turn. On a success, half damage and not stunned.
• Summon Defenders (1/Day). The Brood Mother calls for aid. 2d4 Keth'ri Scouts or 1d4 Keth'ri Warriors arrive in 1d4 rounds.

Legendary Actions (3/round):

• Move. The Brood Mother moves up to half her speed.
• Claw. The Brood Mother makes one claw attack.
Command 2 Actions (Costs). One allied Keth'ri within 1 mile can immediately move up to its speed and make one attack Reaction.
Psychic Pulse 2 Actions (Costs). All creatures within 30 ft must succeed on a DC 20 WIS save or take 22 (4d10) psychic damage.

Loot: Brood Mother's crown (chitin crest, 3,000 credits, can be fashioned into helm granting telepathy 120 ft), royal jelly (rare alchemical substance, heals 50 HP, 1,500 credits), hive core (connection to Keth'ri network, 2,000 credits, can summon 1d4 Keth'ri Scouts 1/day).

Encounter Notes: The Brood Mother is the heart of a Keth'ri colony. Killing her causes all nearby Keth'ri to enter a berserk frenzy (+4 damage, advantage on attacks, cannot retreat) for 1 hour, then they scatter. Negotiating with a Brood Mother is possible—she values the survival and prosperity of her hive above all else. She can offer trade, information, or safe passage in exchange for resources or removal of threats.

Vyr Nomad

Medium Aberration, Neutral Good CR 1

Gaunt grey humanoids with large black eyes. They travel in small family groups, trading prophecy and foresight for food and shelter. Peaceful, fragile, and eerily accurate in their predictions.

HP: 35 (10d8-10) | DV: 13 | Speed: 30 ft

Saves: INT +5, WIS +6 Skills: Insight +6, Perception +6, Persuasion +4 Senses: Darkvision 60 ft, passive Perception 16 Languages: Vyr (whispers), Common, telepathy 30 ft

Foresight. The Vyr Nomad can see glimpses of the immediate future. It has advantage on initiative rolls and cannot be surprised.

Pacifist Nature. The Vyr Nomad will not willingly attack a living creature. If forced into combat, it focuses entirely on defense and escape.

Fragile Body. The Vyr takes double damage from all sources.

Actions (3/turn):

• Telekinetic Shove. The Vyr uses telekinesis to push one creature within 30 ft. The target must succeed on a DC 12 MIG save or be pushed 10 ft away and knocked prone. This deals no damage.
• Prophetic Warning. The Vyr touches a willing creature and grants it advantage on the next saving throw it makes within 1 hour.
• Minor Illusion. The Vyr creates a sound or image (as the minor illusion cantrip) to distract or mislead.
• Trade Prophecy. The Vyr offers a glimpse of the future. The GM can provide one truthful hint, clue, or warning about events in the next 24 hours. This can only be used once per creature per week.

Reactions:

• Precognitive Dodge. When targeted by an attack, the Vyr can use its reaction to impose disadvantage on the attack roll.

Loot: Precognition amulet (grants advantage on one initiative roll, 150 credits), Vyr traveling cloak (provides warmth and camouflage, 75 credits), prophecy scroll (details one future event, 100 credits).

Encounter Notes: Vyr Nomads are refugees from a dying world. They harm no one and ask only for basic necessities in exchange for their foresight. Harming a Vyr is considered deeply taboo among those who know of them—it's said to bring terrible luck. Their prophecies are cryptic but always accurate.

Vyr Elder

Medium Aberration, Neutral Good CR 6

Ancient and wise. This Vyr has lived for centuries, witnessing countless timelines. It can read the threads of fate itself. Extremely fragile physically but nearly untouchable due to its precognitive abilities.

HP: 110 (24d8) | DV: 15 | Speed: 30 ft, fly 30 ft (hover)

Saves: INT +9, WIS +10, PRE +8 Skills: Arcana +9, History +9, Insight +14, Perception +10 Senses: Truesight 60 ft, passive Perception 20 Languages: Vyr, Common, Deep Speech, telepathy 120 ft

Perfect Foresight. The Vyr Elder sees multiple timelines simultaneously. It has advantage on all saving throws and cannot be surprised. Attack rolls against it have disadvantage.

Fragile Form. The Vyr Elder has vulnerability to all damage types.

Timeless Mind. The Vyr Elder is immune to psychic damage, being charmed, and being frightened. It does not age.

Legendary Resistance (2/Day). If the Vyr Elder fails a saving throw, it can choose to succeed instead (by foreseeing the danger and reacting perfectly).

Actions (3/turn):

• Telekinetic Blast. Ranged Spell Attack: +10 to hit, range 120 ft, one target. Hit: 27 (6d8) force damage. The target must succeed on a DC 17 MIG save or be pushed 15 ft away.
• Read Timeline. The Vyr Elder touches a willing creature and reveals a glimpse of its future. The creature gains advantage on all saving throws for 1 minute or learns one important fact about its near future (GM's discretion).
• Temporal Shift (Recharge 5-6). The Vyr Elder manipulates time around one creature within 60 ft. That creature must succeed on a DC 17 WIS save or be stunned for 1 round as it experiences multiple timelines simultaneously.
• Prophetic Guidance. The Vyr Elder provides detailed knowledge about a specific topic, location, or event. This functions as legend lore or divination at the GM's discretion.

Reactions:

• Foreseen Evasion. When targeted by an attack or spell, the Vyr Elder can use its reaction to teleport up to 30 ft to an unoccupied space it can see, causing the attack or spell to miss.

Legendary Actions (2/round):

• Move. The Vyr Elder moves up to its speed.
• Telekinetic Shove. One creature within 60 ft must succeed on a DC 17 MIG save or be pushed 10 ft in a direction of the Elder's choice.
Glimpse of Fate 2 Actions (Costs). One creature within 60 ft gains advantage or disadvantage (Elder's choice) on its next attack roll or saving throw.

Loot: Vyr Elder's staff (focus for divination magic, +2 to spell attack rolls for divination spells, 2,500 credits), seer's circlet (grants detect thoughts at will, 1,800 credits), scroll of prophecy (extremely detailed prediction, priceless to the right buyer).

Encounter Notes: Vyr Elders are revered even among other Vyr. They rarely involve themselves in mortal affairs unless the timeline itself is at risk. If you meet one, it already knew you were coming. Harming a Vyr Elder is nearly impossible—it will foresee and evade almost any attack. They are willing to trade information for protection, resources, or assistance in preserving certain futures.

Skein

Medium Aberration, Unaligned CR 3

A silicon-based lifeform from a high-gravity world. Its body is a semi-fluid crystalline lattice that constantly reshapes itself. Curious, adaptable, and utterly alien in thought.

HP: 65 (10d8+20) | DV: 14 | Speed: 30 ft, climb 30 ft

Saves: END +4 Skills: Stealth +4 Senses: Blindsight 60 ft (senses vibrations), passive Perception 10 Resistances: Acid, fire; bludgeoning, piercing, slashing from nonmagical attacks Immunities: Poison, disease, exhaustion Languages: Understands Common but cannot speak (communicates through light patterns)

Amorphous. The Skein can move through spaces as narrow as 1 inch without squeezing. It can reshape itself as a bonus action to gain advantage on grapple checks or to escape restraints.

Silicon Body. The Skein does not need to eat, breathe, or sleep. It feeds on minerals and heat.

Reflective Surface. When the Skein is hit by a ranged attack, roll a d6. On a 5-6, the attack is reflected back at the attacker.

Actions (3/turn):

• Crystalline Strike. Melee Weapon Attack: +5 to hit, reach 5 ft, one target. Hit: 15 (3d6+3) slashing damage. The Skein can reshape part of its body into a blade, hammer, or spike as needed.
• Envelop. The Skein attempts to grapple one Large or smaller creature (escape DC 14). While grappled, the target is restrained and takes 9 (2d8) bludgeoning damage at the start of each of its turns as the Skein constricts around it.
• Reshape (Recharge 5-6). The Skein rapidly changes form. Choose one:
  • Defensive: The Skein's DV increases by +3 until the start of its next turn.
  • Mobility: The Skein's speed doubles until the end of its turn.
  • Offensive: The Skein's next melee attack deals an additional 9 (2d8) damage.

Reactions:

• Harden. When hit by an attack, the Skein can use its reaction to gain resistance to the damage type of that attack until the end of the attacker's turn.

Loot: Silicon sample (rare material, 200 credits, highly valued by alchemists and artificers), crystalline core (can be used to craft a gem of heat resistance, 300 credits).

Encounter Notes: Skein are not hostile unless threatened. They are curious explorers, often found investigating ruins or unusual geological formations. They communicate through bioluminescent light patterns—patient observers can learn to interpret these. Some settlements keep Skein as "living tools," able to reshape themselves into gears, levers, or even temporary structures.

Thornback

Large Beast (Alien), Unaligned CR 4

A six-legged alien predator with a ridge of bony spines down its back. Incredibly fast. Hunts in packs. Capable of leaping incredible distances to bring down prey.

HP: 80 (10d10+30) | DV: 14 | Speed: 60 ft

Saves: AGI +6, END +5 Skills: Athletics +6, Perception +4, Stealth +6 Senses: Darkvision 60 ft, passive Perception 14 Languages: —

Pack Tactics. The Thornback has advantage on attack rolls against a creature if at least one of the Thornback's allies is within 5 ft of the creature and the ally isn't incapacitated.

Pounce. If the Thornback moves at least 30 ft straight toward a creature and then hits it with a claw attack on the same turn, the target must succeed on a DC 15 MIG save or be knocked prone. If the target is prone, the Thornback can make one bite attack as a bonus action.

Standing Leap. The Thornback's long jump is up to 40 ft and high jump is up to 20 ft, with or without a running start.

Actions (3/turn):

• Multiattack. The Thornback makes three attacks: two with its claws and one with its bite.
• Claw. Melee Weapon Attack: +7 to hit, reach 5 ft, one target. Hit: 19 (3d8+4) slashing damage.
• Bite. Melee Weapon Attack: +7 to hit, reach 5 ft, one target. Hit: 17 (3d6+4) piercing damage plus 5 (2d4) poison damage.
• Spine Volley (Recharge 5-6). The Thornback launches spines from its back in a 30-ft cone. Each creature in the area must succeed on a DC 15 AGI save or take 28 (8d6) piercing damage. On a success, half damage.

Reactions:

• Evasive Leap. When targeted by an attack, the Thornback can use its reaction to leap up to 20 ft to an unoccupied space, potentially causing the attack to miss if it moves out of range.

Loot: Thornback hide (tough leather, can be crafted into light armor with DV 13, 400 credits), spines (12-20 spines, each can be used as a javelin or crafted into caltrops, 5 credits each), poison gland (alchemical, 150 credits).

Encounter Notes: Thornbacks hunt in packs of 3-6. They're ambush predators, using their speed and leaping ability to close distance rapidly. Extremely dangerous in open terrain. They can be found near Breach sites or in wastelands where large prey is common. Domestication has been attempted but usually ends in tragedy.

Luminari

Medium Aberration, Neutral CR 7

Beings of pure energy contained within a spherical shell of crystalline force. They communicate through light and electromagnetic pulses. Peaceful unless provoked, but their electrical discharges are devastating.

HP: 125 (18d8+36) | DV: 16 | Speed: 0 ft (fly 60 ft, hover)

Saves: AGI +9, INT +8 Skills: Arcana +8, Perception +7 Senses: Blindsight 120 ft (senses electromagnetic fields), passive Perception 17 Resistances: Psychic; bludgeoning, piercing, slashing from nonmagical attacks Immunities: Lightning, thunder, paralyzed, prone, restrained Languages: Telepathy 60 ft (electromagnetic signals, requires special equipment or abilities to interpret)

Energy Form. The Luminari does not need to eat, breathe, or sleep. It feeds on electricity and radiation.

Shocking Touch. Creatures that touch the Luminari or hit it with a melee attack while within 5 ft take 9 (2d8) lightning damage.

Illumination. The Luminari sheds bright light in a 30-ft radius and dim light for an additional 30 ft. It can suppress or restore this light as a bonus action.

Actions (3/turn):

• Lightning Bolt. Ranged Spell Attack: +9 to hit, range 120 ft, one target. Hit: 31 (7d8) lightning damage. If the target is wearing metal armor or made of metal, it has disadvantage on the saving throw.
• Chain Lightning (Recharge 5-6). The Luminari releases a bolt of lightning that arcs between targets. Choose one creature within 60 ft. That creature takes 45 (10d8) lightning damage (DC 18 AGI save for half). The lightning then arcs to up to 3 additional creatures within 30 ft of the first target. Each secondary target takes 22 (5d8) lightning damage (DC 18 AGI save for half).
• Electromagnetic Pulse (Recharge 6). All creatures within 30 ft must succeed on a DC 18 END save or be stunned until the end of their next turn. Electronic devices and magical items that rely on electricity cease to function for 1 minute.

Reactions:

• Discharge. When the Luminari takes damage, it can use its reaction to release a burst of energy. All creatures within 10 ft take 18 (4d8) lightning damage (DC 18 AGI save for half).

Loot: Energy core (remains after death, glows with stored power, 1,500 credits, can power magical devices indefinitely), crystalline shell fragment (200 credits, conducts electricity perfectly), electromagnetic data log (stored experiences, priceless to scientists).

Encounter Notes: Luminari are typically peaceful observers. They're drawn to sources of electricity—power plants, storms, lightning-struck areas. Approaching one is safe if you don't carry active electronics or metal weapons. They can be communicated with if you have the right equipment (telegraph, radio, even Morse code via flashlight). They often share astronomical data or warnings about dimensional instabilities.

Spore Carrier

Medium Plant (Alien), Unaligned CR 2

A humanoid body piloted by a fungal intelligence from another world. The host is long dead, but the fungus animates it with eerie precision. It spreads spores wherever it goes.

HP: 50 (8d8+16) | DV: 13 | Speed: 30 ft

Saves: END +4 Senses: Darkvision 60 ft, passive Perception 11 Resistances: Poison, necrotic Immunities: Disease, exhaustion, charmed, frightened Languages: Understands the languages the host knew but speaks in halting, broken sentences

Fungal Resilience. The Spore Carrier regains 5 HP at the start of its turn if it is in a damp or humid environment and has at least 1 HP.

Spore Cloud. Any creature that starts its turn within 5 ft of the Spore Carrier must succeed on a DC 13 END save or be poisoned until the start of its next turn.

Death Burst. When the Spore Carrier is reduced to 0 HP, it releases a cloud of spores in a 10-ft radius. All creatures in the area must succeed on a DC 13 END save or be poisoned for 1 minute. A poisoned creature can repeat the save at the end of each turn.

Actions (3/turn):

• Fungal Fist. Melee Weapon Attack: +4 to hit, reach 5 ft, one target. Hit: 11 (2d6+2) bludgeoning damage plus 5 (2d4) poison damage.
• Spore Spray (Recharge 5-6). The Spore Carrier releases a cloud of spores in a 15-ft cone. Each creature in the area must succeed on a DC 13 END save or take 18 (4d8) poison damage and be blinded for 1 minute. On a success, half damage and not blinded. A blinded creature can repeat the save at the end of each turn.
• Infect. The Spore Carrier touches a creature and attempts to infest it with spores. The target must succeed on a DC 13 END save or become infected. An infected creature takes 5 (2d4) poison damage at the start of each of its turns. The infection can be cured with lesser restoration or similar magic.

Loot: Spore samples (alchemical, can be used to create poison or antitoxin, 100 credits), fungal colony (if harvested, can be cultivated for medicinal or poisonous purposes, 50 credits).

Encounter Notes: Spore Carriers wander aimlessly, spreading their fungus. They cluster in damp, dark places—sewers, basements, caves. Killing one releases spores that can infect others. Fire is the best solution. Some alchemists pay well for live samples (good luck capturing one safely). The fungus is semi-intelligent, capable of basic problem-solving but not complex communication.

Wrath Beetle

Tiny Beast (Alien), Unaligned CR 1/2

Escaped from Keth'ri hive ships. These alien insects swarm in clouds, devouring organic matter with terrifying speed. A single beetle is harmless. A thousand can strip a body to bone in minutes.

HP: 28 (8d4+8) | DV: 12 | Speed: 20 ft, fly 40 ft

Senses: Darkvision 30 ft, passive Perception 10 Resistances: Poison Languages: —

Swarm. The Wrath Beetle swarm can occupy another creature's space and vice versa. The swarm can move through any opening large enough for a Tiny insect. The swarm can't regain HP or gain temporary HP.

Swarm Tactics. The swarm has advantage on attack rolls against any creature that doesn't have all its HP.

Actions (3/turn):

• Bites. Melee Weapon Attack: +4 to hit, reach 0 ft, one target in the swarm's space. Hit: 10 (4d4) piercing damage, or 5 (2d4) piercing damage if the swarm has half its HP or fewer. The target must succeed on a DC 12 END save or take an additional 5 (2d4) poison damage.

Loot: Wrath beetle carapaces (once the swarm is destroyed, can be collected as alchemical components, 10 credits per 100 beetles), hive pheromone (attracts or repels beetles, 30 credits).

Encounter Notes: Wrath Beetles are a plague wherever they appear. Keth'ri hunt them actively to prevent overpopulation. Swarms of 1,000+ beetles (10 swarms) can strip a human body in under 2 minutes. Fire and area-of-effect spells are essential. They're attracted to fresh meat and movement. Calm, unmoving individuals are sometimes ignored.

Crystalline Sentinel

Large Construct (Alien), Unaligned CR 8

A living crystal formation from a high-magic world. It moves slowly but deliberately, reshaping its body to adapt to threats. Immune to most magic and capable of reflecting spells back at casters.

HP: 140 (12d10+72) | DV: 16 | Speed: 20 ft

Saves: END +10, WIS +6 Senses: Blindsight 60 ft (senses vibrations), passive Perception 12 Resistances: Bludgeoning, piercing, slashing from nonmagical attacks Immunities: Poison, psychic, disease, exhaustion, charmed, frightened, paralyzed, petrified Languages: Understands Deep Speech but cannot speak

Crystal Body. The Sentinel does not need to eat, breathe, or sleep. It is vulnerable to thunder damage (shatter).

Magic Reflection. When the Sentinel is targeted by a spell of 5th level or lower, roll a d6. On a 4-6, the spell is reflected back at the caster as if the Sentinel had cast it.

Immutable Form. The Sentinel is immune to any spell or effect that would alter its form.

Actions (3/turn):

• Multiattack. The Sentinel makes two slam attacks.
• Slam. Melee Weapon Attack: +10 to hit, reach 10 ft, one target. Hit: 35 (6d8+6) bludgeoning damage plus 9 (2d8) radiant damage.
• Crystal Shard Volley (Recharge 5-6). The Sentinel launches razor-sharp crystal shards in a 30-ft cone. Each creature in the area must succeed on a DC 19 AGI save or take 45 (10d8) piercing damage. On a success, half damage.
• Reshape (Recharge 6). The Sentinel reshapes its body. Choose one:
  • Defensive Form: The Sentinel's DV increases by +4 until the start of its next turn.
  • Offensive Form: The Sentinel's next slam attack deals an additional 18 (4d8) damage.
  • Reflective Form: The Sentinel automatically reflects the next spell cast at it (no roll required) until the start of its next turn.

Reactions:

• Crystal Shield. When hit by a ranged attack, the Sentinel can use its reaction to gain +5 DV against that attack, potentially causing it to miss.

Loot: Crystalline core (heart of the Sentinel, 2,500 credits, can be used to craft a shield that reflects magic), crystal shards (20-30 shards, each worth 50 credits, can be used as ammunition or spell components).

Encounter Notes: Crystalline Sentinels are guardians of Breach sites or areas of high magical concentration. They're not hostile unless their territory is threatened. Melee combat is inefficient—they're extremely durable. Thunder damage (sonic weapons, shatter spell) is the key weakness. They don't communicate but can be "negotiated" with by demonstrating non-hostility (standing still, backing away, etc.).

Phase Stalker

Medium Aberration, Chaotic Evil CR 6

A predator that shifts between dimensions at will. It strikes from the ethereal plane, drags victims halfway through, and vanishes before retaliation. Nearly impossible to pin down.

HP: 110 (16d8+32) | DV: 15 | Speed: 40 ft

Saves: AGI +7, WIS +5 Skills: Stealth +10, Perception +5 Senses: Darkvision 60 ft, see invisibility, passive Perception 15 Resistances: Necrotic; bludgeoning, piercing, slashing from nonmagical attacks Languages: Deep Speech, telepathy 60 ft

Ethereal Jaunt. As a bonus action, the Phase Stalker can shift from the Material Plane to the Ethereal Plane, or vice versa. While on the Ethereal Plane, it can see and hear into the Material Plane to a range of 60 ft but cannot interact with anything there.

Hit-and-Run. When the Phase Stalker hits with a melee attack, it can immediately shift to the Ethereal Plane as part of the same action (no bonus action required).

Ambush Predator. The Phase Stalker has advantage on attack rolls against any creature that hasn't taken a turn yet in combat.

Actions (3/turn):

• Multiattack. The Phase Stalker makes two claw attacks.
• Claw. Melee Weapon Attack: +7 to hit, reach 5 ft, one target. Hit: 27 (5d8+3) slashing damage plus 9 (2d8) necrotic damage. If the target is a creature, it must succeed on a DC 17 AGI save or be grappled (escape DC 17) and partially phased into the Ethereal Plane, causing it to be restrained.
• Drag Between Worlds. If the Phase Stalker has a creature grappled, it can use an action to shift both itself and the grappled creature to the Ethereal Plane. The grappled creature takes 36 (8d8) force damage as its body is torn between dimensions. The Phase Stalker can then release the creature (leaving it stranded on the Ethereal Plane) or keep it grappled.

Reactions:

• Phase Out. When hit by an attack, the Phase Stalker can use its reaction to shift to the Ethereal Plane, causing the attack to miss. It returns to the Material Plane at the start of its next turn.

Loot: Phase residue (ectoplasmic substance, 200 credits, used in planar magic), dimensional anchor (salvaged from the Stalker's body, prevents ethereal travel within 30 ft, 1,200 credits).

Encounter Notes: Phase Stalkers are apex predators that hunt both planes. They're patient, observing prey from the Ethereal Plane before striking. Fighting one is frustrating—it attacks, phases out, and repeats. See invisibility or true seeing helps track it. Dimensional anchors or forcecage can trap it. Extremely dangerous alone; in groups, nearly unbeatable.

Hive Drone

Tiny Construct (Alien), Unaligned CR 1/4

Part of a distributed intelligence network. Individually, they're almost mindless. In groups, they form a collective consciousness capable of complex problem-solving. They repair, build, and defend Keth'ri installations.

HP: 18 (4d4+8) | DV: 12 | Speed: 10 ft, fly 40 ft

Senses: Darkvision 60 ft, passive Perception 10 Resistances: Poison Immunities: Charmed, exhausted Languages: Understands Keth'ri but cannot speak

Collective Intellect. For every 10 Hive Drones within 30 ft of each other, the group's effective INT increases by 2 (max 18). With INT 10+, they can perform complex tasks. With INT 14+, they can communicate in Keth'ri via synchronized movements.

Swarm Repair. If at least 5 Hive Drones work together for 1 hour, they can repair 10 HP worth of damage to a construct or structure, or build simple tools and fortifications.

Actions (3/turn):

• Shock Touch. Melee Weapon Attack: +4 to hit, reach 5 ft, one target. Hit: 5 (1d4+2) lightning damage.
• Coordinated Attack. If at least 3 Hive Drones attack the same target, they all make attack rolls with advantage.

Loot: Drone circuitry (basic tech component, 10 credits), micro power cell (can power small devices for 1 week, 15 credits).

Encounter Notes: Hive Drones are everywhere in Keth'ri territory—repairing, constructing, patrolling. A single drone is an annoyance. Ten are a problem. A hundred can disassemble a vehicle in hours. They're not aggressive unless defending Keth'ri property or personnel. Some scavengers hunt them for parts.

Gorathi Raider

Large Humanoid (Alien), Chaotic Neutral CR 3

Seven feet of muscle and aggression. The Gorathi are a warrior culture from a harsh world. They raid for resources, glory, and sport. Honorable in their own way—they respect strength and courage.

HP: 65 (8d10+24) | DV: 14 | Speed: 40 ft

Saves: MIG +6, END +5 Skills: Athletics +6, Intimidation +4, Survival +3 Senses: Darkvision 60 ft, passive Perception 11 Languages: Gorathi, Common (broken)

Aggressive. As a bonus action, the Gorathi Raider can move up to its speed toward a hostile creature it can see.

Relentless (Recharges on Short Rest). If the Gorathi Raider is reduced to 0 HP but not killed outright, it drops to 1 HP instead.

Actions (3/turn):

• Multiattack. The Gorathi Raider makes two greataxe attacks.
• Greataxe. Melee Weapon Attack: +6 to hit, reach 5 ft, one target. Hit: 15 (2d10+4) slashing damage.
• Javelin. Ranged Weapon Attack: +6 to hit, range 30/120 ft, one target. Hit: 11 (2d6+4) piercing damage.
• War Cry (Recharge 5-6). All allies within 30 ft gain advantage on their next attack roll, and all enemies within 30 ft must succeed on a DC 14 WIS save or be frightened until the end of their next turn.

Reactions:

• Retaliatory Strike. When hit by a melee attack, the Gorathi Raider can use its reaction to make one greataxe attack against the attacker.

Loot: Gorathi greataxe (masterwork, 200 credits), tribal token (proof of honor kill, can be traded to other Gorathi for safe passage or trade, 50 credits), scavenged gear (random salvage, 2d20 credits worth).

Encounter Notes: Gorathi Raiders travel in warbands of 4-8. They respect opponents who fight well—surrender with dignity might earn you mercy. Cowardice or trickery earns only contempt. They're raiders, not murderers—they take what they need and leave. Killing the warband leader in single combat can end hostilities (or enrage them, depending on how it's done). They value trophies and scars.

The Emissary

Large Aberration, True Neutral CR 12

A powerful alien observer from a civilization so advanced it might as well be gods. It does not interfere—it merely watches, records, and reports. But if attacked, it will defend itself with overwhelming force.

HP: 200 (18d10+90) | DV: 18 | Speed: 40 ft, fly 60 ft (hover)

Saves: INT +12, WIS +11, PRE +11 Skills: Arcana +12, History +12, Insight +11, Perception +11 Senses: Truesight 120 ft, passive Perception 21 Resistances: Radiant, necrotic; bludgeoning, piercing, slashing from nonmagical attacks Immunities: Psychic, poison, charmed, frightened, exhausted Languages: All, telepathy 1 mile

Observer Protocol. The Emissary does not initiate combat unless attacked or unless its mission is directly threatened. It will attempt to de-escalate or withdraw before fighting.

Advanced Technology. The Emissary's "magic" is actually advanced technology indistinguishable from magic. It cannot be counterspelled or dispelled by normal means.

Legendary Resistance (3/Day). If the Emissary fails a saving throw, it can choose to succeed instead.

Force Field. The Emissary is surrounded by a personal force field. It has 50 temporary HP that regenerate at the start of each of its turns if not destroyed.

Actions (3/turn):

• Multiattack. The Emissary makes three energy lance attacks.
• Energy Lance. Ranged Spell Attack: +12 to hit, range 120 ft, one target. Hit: 51 (8d10+7) radiant damage.
• Disintegration Beam (Recharge 5-6). The Emissary fires a beam of pure energy at one creature within 120 ft. The target must succeed on a DC 23 AGI save or take 90 (20d8) force damage. If this reduces the target to 0 HP, they are disintegrated.
• Temporal Stasis (Recharge 6). One creature within 60 ft must succeed on a DC 23 WIS save or be frozen in time for 1 minute. The creature is incapacitated and invulnerable to all damage. At the end of the duration, the creature reappears in the same space (or the nearest unoccupied space) and can act normally.
• Teleport. The Emissary teleports up to 120 ft to an unoccupied space it can see.

Legendary Actions (3/round):

• Move. The Emissary moves up to its speed or teleports up to 60 ft.
• Lance. The Emissary makes one energy lance attack.
Analyze 2 Actions (Costs). The Emissary scans one creature within 120 ft, learning its current HP, resistances, vulnerabilities, and general capabilities.
Force Pulse 2 Actions (Costs). All creatures within 30 ft must succeed on a DC 23 MIG save or be pushed 15 ft away and knocked prone.

Loot: Data core (contains millennia of recorded observations, priceless to scholars, governments, or anyone who wants to understand the universe), energy cell (powers any device indefinitely, 10,000 credits), personal shield generator (grants 20 temp HP at the start of each day, 15,000 credits).

Encounter Notes: The Emissary does not care about human conflicts. It is here to observe the Breach and its effects. It will answer questions politely but offers no help or interference. Attacking it is suicidal—it has overwhelming firepower and will escalate only as much as necessary. If destroyed, its civilization will send another. And another. And eventually, they may decide humanity is a threat worth addressing.

End of Chunk 3: Eldritch Horrors & Alien Species

This bestiary chunk introduces creatures from beyond Earth—horrors from between dimensions and aliens from distant worlds. Each creature is mechanically complete, statistically balanced to CR, and thematically distinct. The Breach has brought wonders and nightmares in equal measure.
