  • Collecting and playing Chaos armies in Warhammer 40k offers huge variety in modeling and tactical options

The Immaterium – A Psychic Mirror Realm of Chaos

The Immaterium, also known as the Warp, is an alternate psychic dimension that mirrors the material universe of 40k. It seethes with the raw, unbound energies of mortal souls and emotions across the galaxy. This metaphysical realm is the birthplace of the Chaos Gods and their daemonic servants.


The Warp does not adhere to linear time or the laws of physics. It is an ever-changing maelstrom ruled by the whims of its denizens. Venturing into the Immaterium unprotected leads to insanity, possession, and damnation. It is from this nightmare realm that the greatest threat to humanity arises.

The Ruinous Powers – Dark Gods Seeking to Corrupt Reality

Within the Warp exist powerful entities known as the Chaos Gods or Ruinous Powers. They were formed from the collective psychic reflections of mortal experiences and beliefs over eons. Each Chaos God embodies a metaphysical concept, which defines their sphere of influence:

Khorne, the Blood God, represents rage, war, murder, and senseless killing. His domain is strewn with brass fortresses decorated with the skulls of his victims.

Nurgle, the Plaguefather, is the god of disease, decay, and death. His “garden” in the Warp teems with rot and corruption.

Tzeentch, the Changer of Ways, governs hope, ambition, fate, and change. His dimension is an ever-shifting cosmic maze.

Slaanesh, the Prince of Pleasure, indulges every hedonistic excess. Their palace at the Warp’s core caters to every dark desire.


The Chaos Gods seek to manifest in realspace to spread mayhem and remake it into their twisted domains. They use their powers to corrupt mortal souls and turn them into loyal servants who will weaken the veil between realms.

Chaos Space Marines – The Traitor Legions

The Chaos Space Marines were once loyal warriors of the Emperor until they were seduced by the dark promises of the Ruinous Powers. During the Horus Heresy, fully half of the Space Marine legions rebelled against the Imperium, led by Warmaster Horus.

Though defeated, those traitor legions did not die out. Blind with hatred for the Emperor, they fled into the Eye of Terror and became warped by centuries dwelling in the Immaterium. There they fight as bitter, spike-armored warriors enslaved to Chaos.

Chaos Space Marines Warhammer 40k

The most infamous traitor legions include:

  • The Black Legion – Successors of Horus’ own Sons of Horus legion, led by Warmaster Abaddon
  • World Eaters – Bloodthirsty berzerkers devoted to Khorne
  • Death Guard – Plague Marines with diseased, rotting flesh who serve Nurgle
  • Thousand Sons – Sorcerer Space Marines who sold their souls to Tzeentch
  • Emperor’s Children – Hedonistic perfectionists who worship Slaanesh

Though fragmented into rival warbands, the traitor legions unite to prosecute the Long War against the Imperium. Each pursues its own twisted Chaotic dogma as they battle to destroy the mortal realm.

The Lost and the Damned – Mortal Servants

Not all who serve the Chaos Gods are transhuman warriors. Among the teeming ranks of Chaos are many mortals who have turned from the Emperor’s light to kneel before the dark altars of the Ruinous Powers:

Chaos Cultists are fanatical worshippers driven by dark prophecies and led by depraved demagogues. These deluded humans see Chaos as an emancipation from the tyranny of the Imperium.

The Dark Mechanicus are tech-adepts of Mars who seek forbidden knowledge. Using Warp-tainted machines, they create twisted daemon engines and weapons for their patrons among the Chaos Space Marines.

Renegades are Imperial Guard regiments, planetary defense forces, and spacefleets who have renounced their oaths to the Emperor and embraced heretical beliefs.

Mutants are the wretched spawn of Chaos who have been transformed by exposure to its corrupting energies. They are shunned, but find purpose in serving the Ruinous Powers.

Daemons of the Warp – The Neverborn Servants of Chaos

When the psychic tides of the Immaterium swell strong, they allow the unholy minions of the Ruinous Powers to tear open the fabric of reality and emerge into the material realm. Led by hulking Greater Daemons, hordes of bizarre Lesser Daemons pour forth from the breach, appearing as physical manifestations of the Chaos Gods’ will.

These supernatural entities are often called the Neverborn, as they have no physical bodies of their own. They are coalesced from the raw psychic energy and emotions seething within the Warp, temporarily giving shape to formless Warpstuff. When their hold on realspace falters, Neverborn daemons dissipate back into the Immaterium, only to re-form again later when the barrier is breached anew.

The most common and recognizable types of Chaos daemons include:

Bloodthirsters – Immense, winged demons wreathed in flowing blood who live to slaughter mortals in Khorne’s name. They wield massive axes and whips forged from the raw fury of the Warp, capable of slaying the mightiest enemies with a single blow.

Daemonettes – Lithe, sensuous fiends who serve Slaanesh by dispensing excruciating ecstasies. Their crab-like claws rend flesh, while their hypnotic dances entrance victims, allowing them to draw out both pleasure and pain endlessly before granting the release of death.

Plaguebearers – Shambling, putrid daemons of disease and entropy who count themselves amongst Nurgle’s most blessed children. Their corpulent, rotten bodies are wracked with every contagion imaginable. Wherever they march, they spread their delirious plagues that bring planetary populations to their knees in agony.

Horrors – Multi-limbed abominations of raw magic, who are fragmentary aspects of Tzeentch’s endless well of sorcery. Their constantly shifting bodies mutate as they cackle eldritch flames upon their foes. Though weak individually, they appear in vast numbers to overwhelm the enemy with waves of unnatural power.



Nurgle Lord

Great Unclean Ones – These grotesque behemoths are Greater Daemons swollen with the unholy might of Nurgle himself. Their mountainous bodies overflow with filth and corruption. With a single gesture, they can spread plagues capable of exterminating entire worlds.

Keepers of Secrets – Serpentine Greater Daemons of Slaanesh, granting twisted desires to their victims as they pierce hearts with their bladed limbs. Their lithe forms entrance and beguile even as their claws claim your soul forever.

Lords of Change – Monstrous avian sorcerers utterly devoted to Tzeentch’s inscrutable designs. A Lord of Change can rewrite destinies with a thought. Their sorceries sow pure randomness and anarchy across entire battlefields.

In the material realm, daemons are tireless warriors unburdened by mortal needs and fears. They fight with supernatural strength and speed, appearing anywhere the Warp breaches through. So long as even a flicker of the Ruinous Powers’ magical influence remains, daemons can continue to wreak havoc upon realspace.


The Allure of Chaos

Despite their dark nature, there is an undeniable allure to the forces of Chaos that tempts many mortals into their service. Chaos promises its followers:

Forbidden Knowledge – The chance to plumb secrets and work magicks barred by the Imperium

Power – Gifts of strength and sorcery sufficient to crush one’s enemies and rival that of Space Marines

Pleasure – Experiences of such delightful excess most humans cannot imagine them

Revenge – The opportunity to pay back perceived injustices towards mutants, psykers, abhumans, and aliens by the intolerant Imperium

No wonder so many cast off the corpse-god Emperor’s shackles to reach for Chaos’ corrupting embrace. The path may lead to damnation, but the rewards along the way are a darkly tempting prospect for many…

Playing Chaos Daemons on the Tabletop

One of the great joys of collecting Chaos Daemons is the sheer variety of bizarre entities you can field in your Warhammer 40k armies. Here’s a quick overview of how to build your daemonic forces using Games Workshop’s rules:

  • Bloodletters – The core infantry, these dog-headed, axe-wielding Khorne daemons excel at melee combat. Send 20-30 in a unit to tear apart enemies.
  • Plaguebearers – Shambling hordes of 50+ Nurgle daemons. Not as damaging in melee but highly resilient due to the “Disgustingly Resilient” rule.
  • Daemonettes – Fast, deadly Slaanesh troops. Use their speed and fight skills to outflank and destroy vulnerable backline units.
  • Horrors – Spamming lots of these cheap Tzeentchian daemons lets you blast enemies with endless psychic mortal wounds.
  • Fiends – Whipping, lashing Slaanesh beasts perfect as shock cavalry to smash apart infantry.
  • Flesh Hounds – Khorne’s vicious warp-hounds bound with brass collars. Use 5-10 in a pack to hunt down enemy characters.
  • Daemon Princes – Monstrous winged daemon heroes who lead your army. Give them devastating close combat weapons and psychic powers.
  • Greater Daemons – Epic god-avatars like Bloodthirsters and Keepers of Secrets anchor your battleline with their might.

Mix and match daemonic legions to create uniquely chaotic armies devoted to one or all of the Dark Gods!



I hope this overview helps showcase just how complex, compelling, and deliciously sinister the Chaos factions of Warhammer 40k truly are. As both a collector and player, I’m endlessly fascinated by the shadowy denizens of the Warp and how their unholy crusade clashes with the beleaguered forces of the Imperium.

From the spikiest Chaos Space Marine to the lowliest gibbering horror, these models provide fantastic opportunities for hobbyists to build, convert, and paint creations dripping with chaotic character. Just beware – like so many in the grim darkness of the far future, you too may come to find the lure of Chaos irresistible!
