The Chaos Gods and the Forces of Chaos that serve them are the greatest enemies of the Imperium of Man, the Eldar and most other sentient forms of life in the Milky Way Galaxy, even if they are not fully aware yet of the threat Chaos poses, like the Tau Empire. The Chaos Gods are able to devote a fraction of their psychic power in the Warp to create daemons, whose appearance and character reflect their patron God's own nature. These daemons may be reabsorbed into the God at their whim. The least of the minor Gods may be so limited in their power that expending that power to create a daemon means their entire power is expended; in effect, the God becomes a daemon.
