The Chaos Gods, also called the Dark Gods or the Ruinous Powers, are powerful entities who inhabit and control the psychic dimension that underlies all physical reality known as the Immaterium or the Warp, created and sustained by the emotions and collective desires of every sentient being of the material universe. Although they are god-like beings, the Dark Gods are by their nature monomaniacal and completely single-minded since they are formed entirely of a single emotion or concept. The Chaos Gods are dependent upon the emotions of mortal creatures, especially the hordes of humanity, for their power and continued existence. As a result, the Chaos Gods strive to convert all mortals to their worship and service so that they may ultimately dominate the universe. However, if they were to win such a dark victory, it would likely destroy all of reality when the dimensional separation between realspace and the Immaterium broke down in its wake.
