John was a soldier in Genkaku's army during the Great War, where John established himself as a top sniper. Certain events forced him to Scarlet Moon, where he was a minor participant in the War of Succession and met Zonder. Since he has been something of a mentor to Zonder, and the two traveled north and ended up in Highland, where they fight to this day. John is not young by any means at 54, but by looking at him you wouldn't know it.
