Chaos

Chaos, also known to its servants as the Primordial Truth or the Primordial Annihilator, and to the Imperium of Man as the Archenemy, is the universal and usually malign spiritual force embodied by the malevolent intelligent entities comprised of psychic energy that live in the Immaterium.

The entities who embody Chaos are mostly the beings of pure psychic energy called the Chaos Gods and their daemonic servants, but the term also encompasses those mortals who have thrown in their lot with Chaos.

These range from simple peasants and/or manufactorum labourers who serve as Chaos Cultists, to Traitor Imperial Guardsmen, planetary militia, Imperial nobles, Planetary Governors, and even the mighty Chaos Space Marines and Traitor Titan Legions of the Dark Mechanicum.
