 The cloak appears to be a part of the Outsider and is used for attacks and defense, allowing the outsider to curl up into a ball and grab objects with the cloak.Like other Outsiders, He Who Walks Before has no respect for The Accords and ignores the neutral ground signage at Mac's pub.During the battle at Demonreach, the Outsider demonstrates a powerful psychic attack ability, convincing Harry, albeit briefly, that Mab is here condemning him for his actions.
