The Warriors of Chaos are the mortal champions of the Ruinous Powers — men and women who have pledged their souls to the Dark Gods in exchange for power, mutation, and the chance to lead the great tide of Chaos southward to consume the Old World. They are the most feared warriors in existence, their bodies warped by daemonic gifts, their minds consumed by the will of their patrons.

The Warriors of Chaos have launched countless invasions of the Old World, each one threatening to overwhelm civilization. The Great War Against Chaos, led by the Everchosen Asavar Kul, nearly destroyed the Empire before Magnus the Pious rallied humanity. The Storm of Chaos, led by Archaon the Everchosen, came even closer. Each invasion leaves scars that take generations to heal.

Chaos Warriors are individually the most powerful mortal soldiers in the world — heavily armoured, supernaturally strong, and utterly fearless. Chaos Knights on daemonic steeds are unstoppable shock cavalry. Chosen Warriors bear the greatest gifts of the gods. Daemon Princes — mortals who have ascended to daemonhood — lead the most powerful warbands. Chaos Spawn, the failed champions who received too many gifts, serve as monstrous shock troops.

There is no culture among the Warriors of Chaos — only the endless pursuit of power and the favour of the Dark Gods. Champions compete to attract divine attention through acts of slaughter and conquest. The Everchosen, chosen by all four Chaos Gods, is the supreme warlord who leads the great invasions. Warbands are constantly shifting as champions rise, fall, and are consumed by mutation.
