Fighting alongside an unidentified and powerful Wolf Lord, his Wulfen guard slew the Night Lords Chaos Lord Sinax. Only a few solar days later and five light years away, Sternhammer was reportedly sighted once more, leading a boarding action aboard an Imperial Navy vessel that resulted in the scuttling of the Light of Fatidicus, so that the enemy would not capture it. More than a hundred victories were attributed to Wolf Priest Sternhammer and his warbands during the 13th Black Crusade. Whether they were the same band, or many, and whether Sternhammer led them all himself is unknown, but the defenders of the Cadian Gate remain both heartened and terrified at the memory of the mournful howls of the Wulfen he led into combat.
