The Chaos faction is one of Warhammer 40,000s mostunique mainstays, portraying a symbiotic relationship between human nature and its hellish reflection in the warp. The eldritch Chaos Gods formed in the Warp as a response to mortals emotions, rather than simply as a force of nature. Their worshippers and Daemons reflect this by being consumed by the aspects of themselves that most reflect their patrons. These aspects range from the rage and bloodlust of Khorne, to the pride and perverseness of Slaanesh, to simply a mix of hatred and selfishness in Chaos Undivided.
