Excalibur is the legendary blade wielded by King Arthur, said to have magical properties or represent a king's right to rule over all of Great Britain. In some versions, the sword in the stone and Excalibur are the same thing but in most they are separate. The Lady in the Lake is the one who gives Arthur the sword in the versions where it is not the sword in the stone. The attributes of Excalibur include words engraved on opposite sides of the blade, a scabbard that will prevent death by wounds or not bleed at all, and the power to create a light that blinds his enemies when he pulls the sword from the stone.
Known as the Ame-no-habakiri (天羽々斬剣, Ame no Habakiri no Tsurugi)?, it is kept within a stone in the Fairy Forest. Due to its ability to damage Shesha, the Divine Powers send Titan to obtain it and burn the forest to the ground.
