'The Once and Future King' was the son of Uther Pendragon and Lady Igraine. Uther disguised himself as Igraine's husband Gorlois to sleep with her. Arthur wields the legendary sword Excalibur and rules the Britons from the castle of Camelot beside his wife, Queen Guinevere. The stories of Arthur and his Knights of the Round Table are recounted by Geoffrey of Monmouth in Historia Regum Britanniae, works by Chrétien de Troyes, and Thomas Mallory's Le Morte d'Arthur, among others. The different sources disagree on various details; for instance, some sources state that Arthur received Excalibur from the Lady of the Lake, while in others he pulls the sword from a stone. After the Battle of Camlann, King Arthur gives Excalibur to his marshal, Sir Bedivere, and is taken to the isle of Avalon to die.
