The Punishment Crusade was initiated by Castellan Draco of the Black Templars Space Marine Chapter and comprised numerous raids on the human populations of worlds fallen under the influence of the expansionist Tau Empire. Notorious for subverting the loyalties of Imperial subjects in their quest to expand the borders of their Empire, the Tau are an ever growing threat and thorn in the side of the Imperium of Man in the Eastern Fringe of the galaxy. But those who stray from the Emperor’s Light cannot go without punishment and Castellan Draco has been tasked with ensuring that the Tau and their human Gue'vesa Traitors feel the wrath of divine retribution.
