Exile was the only way to protect his family. Cahal’s soul hardened away from his loved ones. Don Cahal’s black jacket, proudly wear the arun’s badge of patronage, and transform into a wolf when your pack is threatened.
He can transform into a wolf and into the form of a Crinos, a huge, dangerous beast.
Each form has its advantages: a wolf is harder to spot, a werewolf can easily tear enemies to shreds, and in human form, Cahal can speak freely with others.
