Warhammer 40k: I'm the Imperial Regent, Now What!?

Chapter 58: [Known Chaos Hostile Factions – M41.998.05 Archive Entry]

Classification: Omega-Level Containment Risk

Compiled by: Inquisitorial Archive "Black Vault Theta-13"

Purpose: Strategic reference for primary agents of Ruinous Powers

Access Level: Inquisition Only – Thought for the Day: "To Know the Enemy is to Hate with Precision"

"The Warp births nightmares, and Chaos gives them form. These are not armies—they are blasphemies given flesh."

I. The Chaos Gods (The Ruinous Powers)

Function: Primordial entities that rule over the Immaterium (Warp)

Nature: Manifestations of mortal emotion and psychic resonance

The Four Great Powers:

Khorne – God of blood, war, and rage "Blood for the Blood God!" Tzeentch – God of change, sorcery, and fate "All is planned. All is lies." Nurgle – God of decay, disease, and entropy "Rejoice in rot." Slaanesh – God of excess, pleasure, and sensation "Perfection through indulgence."

Each god maintains a daemonic realm within the Immaterium, a reflection of their corrupt nature.

II. The Traitor Legions (Heretic Astartes)

Function: Former Space Marine Legions who turned against the Emperor during the Horus Heresy

Status: Scattered, immortal, still active across millennia

Primary Legions:

Black Legion (formerly Luna Wolves) – led by Abaddon the Despoiler World Eaters – Khorne-worshiping berserkers Death Guard – Plague Marines of Nurgle Thousand Sons – Sorcerers of Tzeentch Emperor's Children – Hedonists of Slaanesh Night Lords – Terror tacticians, fear specialists Iron Warriors – Siege masters and fortification breakers Word Bearers – Dark apostles, spreaders of warp cults Alpha Legion – Saboteurs, double agents, master infiltrators

Each Legion has splintered into countless warbands, some retaining loyalty to their original Primarchs, others pledging themselves directly to a Chaos God.

III. Daemons of Chaos

Function: Warp-spawned entities, manifestations of the gods' power

Types:

Greater Daemons – Named demigods of ruin Lesser Daemons – Rank-and-file horrors Daemon Princes – Former mortals ascended to daemonhood

Subspecies (per God): Khorne: Bloodthirsters, Flesh Hounds Tzeentch: Lords of Change, Flamers Nurgle: Great Unclean Ones, Nurglings Slaanesh: Keepers of Secrets, Daemonettes

Even a single daemon's incursion into realspace requires ritual, sacrifice, or catastrophic warp breach.

IV. Chaos Cults

Function: Mortal agents and worshippers of the dark gods

Appearance: Found on nearly every Imperial world

Types:

War Cults: Openly militant, seeking to rise in armed rebellion Psykic Covens: Tzeentch-aligned sorcerer circles Pox Congregations: Nurgle-plague spreading subcultures Pleasure Circles: Secretive, Slaanesh-inspired excess cults Red Churches: Bloody temples offering sacrifices to Khorne

Cultist cells are often sleeper agents awaiting activation or guidance from a higher daemonic patron.

V. The Dark Mechanicum

Function: Traitor tech-priests and corrupted Forge Worlds

Seat: Unknown – primary strongholds in the Eye of Terror and the warp-lost forge-world Zar'Kul

Role: Develops daemon engines, warpforged weapons, and twisted machine spirits

Creations:

Defilers Warp-smiths Hellforged Titans Soul-grinders

"The Machine God is dead. Let the scrap sing praises to the Warp."

VI. Chaos Knights & Titans

Function: Former loyalist houses and god-machines corrupted by Chaos

Seat: Fallen Knight Worlds such as Voidmoor, Daemonica

Types:

Knight Despoilers – corrupted versions of Imperial Knights Hell-Walkers – daemonic titans used by the Legio Damnum Infernal Households – wandering knight warbands sworn to individual Chaos Gods

VII. Renegade Chapters & Warbands

Function: Post-Heresy Space Marine defectors and independent traitor groups

Status: Dozens recorded; origins often murky or classified

Examples:

The Red Corsairs – led by Huron Blackheart The Crimson Slaughter – plagued by daemonic voices The Scourged – Tzeentch-bound seers The Flawless Host – Slaanesh-blooded perfectionists The Skulltakers – gladiators of Khorne

Not all who serve Chaos were born into it—some were made by betrayal, vengeance, or madness.

VIII. The Lost and the Damned

Function: Mortal chaos-aligned armies

Composition: Former PDF, enslaved populations, traitor guardsmen, mutants, warp-beasts

Role: Cannon fodder and mass uprisings during Chaos incursions

Alliances: Often support Traitor Legions during Black Crusades
