Angus originates from the Space Marine Chapter The Iron Falcons and during the civil war that pitted the Iron Falcons against their mutated brothers of the 8th and 9th company who had named themselves the 'Sons Of Shadow' Achillius and his staff where called into investigate. Proiteus who was still an Acolyte back then was assigned on a mission to gather important information and Angus and his squad was assigned to protect Proiteus. The mission was achieved however on the way back the team was ambushed from all sides, the battle was long and hard but in the end only Angus and Proiteus remained. After that Angus was assigned to Achillius staff after which he spent most of his time with Proiteus and soon they developed a strong friendship. After the conflict Achillius when elsewhere and Angus rose to the rank of captain following many successful campaigns. 7 years later Proiteus returned to the Iron Falcons requesting that Angus join his staff. Angus felt honored but knew that his loyalties were to his chapter. So Proiteus made an agreement that he would call Angus only when his strength and skill was needed. Angus bears the mark of the Inquisition in the form of a Deathwatch shoulder pad however he continues to bear the colors of his chapter.
