Witch Hunters are a secretive body, devoted to the Emperor, of the Inquisition ready to defend humanity against the dangers of the witchcraft, heresy, and mutation. Witch Hunters of Ordo Hereticus command great power that they can enlist any armed forces of the Imperium, even the elite Space Marines and Grey Knights of other Inquisition branches.

Witch Hunters, unlike their Daemonhunter brothers, have the command of the fighting arm of the Ecclesiarchy, the Sisters of Battle, whom are the some of the best and bravest warriors in the Imperium that equal any Space Marine Chapter.

Witch Hunters, with the Sisters of Battle, are the shining example of purity, faith, and devotion of humanity.
