He is an ex-member of the Companions. He was asked to leave because his "unorthodox" methods were offensive to other members. It is unclear what these methods were or how they were offensive, however, given his current status, it seems possible he used underhanded, duplicitous techniques that would have offended the Companions' sense of honor. He joined The Circle and became a werewolf prior to his expulsion. His voice is deep and gruff, and accompanied by a North American accent, however given that he is a Nordic man, I would love to see a more Scandinavian portrayal.
