Chaos

Chaos is the power of the warp, ruled by four great gods: Khorne the Blood God, Tzeentch the Great Sorcerer, Nurgle the Lord of Decay and Slaanesh the Lord of Pleasure. During the Horus Heresy nine Space Marine Legions rebelled with Horus; defeated, the Traitor Legions fled into the Eye of Terror and remain there ten thousand years on. Each Legion keeps its own character, and its Champions bear the gifts and mutations of the gods they serve. When a great Champion unites the Eye, its hordes pour out: daemons, Cultists and Beastmen marching behind the Chaos Space Marines.
