The Donian Crusade was carried out by the Black Templars Space Marine Chapter beginning in 985.M39 to combat the swelling Ork population sweeping through the Donian Sector and surrounding wilderness space in the southern Segmentum Pacificus. The original Crusade Marshal, Brother Austein, was tragically killed in battle on the planet Nickel V, and was succeeded by Marshal Wernher in 988.M39. The Donian Crusade lasted for roughly 17 years before the High Marshal declared it successful in c.002.M40. Wernher went on to later become the Marshal of the Thangdorn Crusade.
