He was the eldest son of Lord Sir Rysel Gahrvai, Earl of Anvil Rock, and the commanding officer of the field army. He commanded the Corisandian army at the Battle of Haryl's Crossing, where he was heavily defeated by the invading Charisians, but managed to extricate half his army and retreat to a strong defensive position at Talbor Pass, momentarily checking the Charisian advance.
