Oliver is a young man prone to over thinking and quick to anger. He's a fighter and despite wanting to be a simple blacksmith back home with his mom he has been thrust into the adventurer's life. While still very much a 14 year old boy, he tries to act like an adult and tries to be stoic and angry. This stoicism hides a very nervous constant over thinking, from what he is and could be doing, to what he's done and will do all of these thoughts race through his mind as he wildly improvises his way into a fine adventurer.
