He is a large man with scraggly brown beard and piercing blue eyes and gained his position by fighting his rivals in hand-to-hand combat. Also like his predecessors he led several raids against Indrie but never managed to gain a hold within the city.
John Farson recruited him as an ally with Edoacer signing a treaty agreeing to help Farson in overthrowing The Affiliation, and that he was regarded the General of all the Troitan legions. With the aid of Farson the Barony of Cressia fell with Indrie burned to the ground.
