Chaos Cultists are human followers of the Dark Gods. Secret Chaos cults hide on countless Imperial worlds, made up of the poor, the desperate, the ambitious and the corrupt. When Chaos warbands arrive, the cults rise up to support them and open the way for the Traitor Legions.
On the battlefield, Cultists are poorly armed and trained, but they are numerous and fanatical. Their masters spend their lives without hesitation, using them as human shields and cannon fodder.
Chaos cults grow everywhere the Imperium has spread. Some are blood-soaked tribes on feral worlds, others philosophical secret societies on advanced planets. The Imperium's harsh rule breeds discontent, and agents of Chaos foster it. Cults hide behind fronts such as trade guilds, radical political movements, noble houses and worker brotherhoods. They are careful to avoid the Arbites and the Inquisition. Over time a cult may come to rule a town, a hive or a whole world.
The Ordo Hereticus stresses that cultists can come from any background: soldiers, hive gangers, bored nobles or desperate labourers. When the cult rises, hidden weapons and improvised armour come out and gangs fight to overthrow the planet one hab-block at a time.
Cultists come from every background: violent soldiers, hive gangers, decadent nobles, deserters, persecuted abhumans and mutants. All turn to Chaos hoping to improve their lot. Cults often attach themselves to the most fearsome traitor warband, and many people have set out to throw themselves at the feet of the Crimson Slaughter, whom they see as incarnations of the Dark Gods. In the Era Indomitus, the Exilarchy was a vast army of cultists, Traitor Guard and mutants, joined by several Heretic Astartes warbands, operating in Elara's Veil.
Appearance & wargear
Cultists wear ragged clothes, scavenged armour, masks and hoods, often with Chaos marks, and carry autoguns, pistols and close-combat weapons.
Cultists wear whatever they have, such as work clothes, salvaged armour, robes and masks, along with crude symbols of their god. They carry stub guns, autoguns, autopistols, knives, heavy stubbers and flamers.
Cultists wear whatever they can find: scavenged flak armour, rags, robes and crude icons of the Dark Gods. They carry autoguns, stubbers, knives and heavy stubbers, and they become more mutated the longer they serve.

Battlefield role & tactics
Chaos Cultists are cheap, numerous troops for holding objectives and screening Chaos Space Marines.
Cultists are cheap and numerous. They hold ground, screen more valuable warriors and soak up fire. Chaos Space Marines treat them as expendable. Their real value is often before the fighting starts: sabotage, assassination and an uprising timed to a warband's arrival.
Cultists are cheap, numerous expendable troops who screen better units, hold objectives and swarm the enemy. Some armies, such as the Tzenvar Kaul, use mutants as third-line troops for hazardous labour and forlorn hopes. Individually they are weak.
Notable battles & users
- Black Crusades: cults rise on Imperial worlds to support the invading warbands.
- Baraspine (Calixis Sector): a mutant revolt among the workers of the Impellor Towers threatened to plunge the hives into darkness.
