Chaos Warriors are the most powerful of the mortal warriors in the service of the Chaos Gods. Most of them are warriors from the Chaos Marauder tribes, fighters who showed exceptional skill and prowess, and have been recognized by the gods of Chaos themselves.

To win the favour of their chosen god they join a Chaos warband. As Chaos Warriors they accept a life of bloodshed and brigandage in return for the chance to win their master's favour. Such favours, once granted, are not always welcome, for the Chaos gods are fickle and inhuman and their gifts often take the form of gross physical deformities.

Many Chaos Warriors come from amongst the tribes of the Chaos Marauders, but there are others as well. From the warrior classes of the Empire, Kislev and even Bretonnia come nobles bored with their life, seeking excitement, adventure and power. Others are outcasts from society: brigands, bandits and impoverished men who have nowhere else to turn. There is a comfort in belonging, even if the cost will be your very soul.

Chaos Warriors are fighters of unmatched prowess. Imbued with the power of Chaos and often encased in potent Chaos armour, they rarely find their match in combat.

Many followers of Chaos sprout tentacles, horns and scales upon their skin, or suffer disfiguring mutations of other kinds. Often their minds are affected as well leaving them liable to fits of rage, feeble mindedness, uncontrollable hysterics, and other aberrations of the spirit. But not all the rewards of Chaos are disadvantageous. Sometimes the gods change their followers in ways that enhance their physical and mental powers conferring gifts of magic, immunity from harm, incredible beauty, and immense strength.

Every Chaos Warrior prays that his god will one day choose him to be one of his Champions. As a Champion he receives further rewards, perhaps even the ultimate reward of daemonhood and immortality, for there is nothing a god cannot do and no favour that he cannot grant.
