Bjørn is a destructive force that was sealed away ages ago by the Briscoletti family. Not much is known about what he's actually like as a person, but he's got a serious vendetta against Rodolfo Briscoletti—the last member of the family who trapped him before the events of the game. He doesn't get a ton of screen time, but when he does speak, he's got a thick Nordic accent that's pretty hard to miss. Since he can't find Rodolfo, he just takes out his rage on anyone unfortunate enough to cross him, including the player's party.
