He offered his life in place of Crow’s life to the Cabal Empire after he killed a Psion ally accidentally. Caiatl basically took advantage of being offered a seasoned warrior and leader and ordered his sentence be carried out as servitude on her War Council, making him a Bracus. A Valus challenged him to single combat due to tensions about a human on the War Council and he killed him no Light required, earning his title before all who stood to watch. It was the sixth in three days. To put it into perspective by the way, Bracus is the lowest rank a Cabal officer can have (to my memory). Valus is the second highest in a Cabal Legion, meaning in terms of the military he’s in the third ring of the chain of command. I’m not sure if Caital even supports the existence of Primuses given her uniform colours, I’d have to check the names of the friendly Cabal but if she doesn’t, my man Saladin has command of his own ships and only answers to the Empress.
