Viviean, or Nimue, is the water goddess known better as the Lady of the Lake. In the world of Medieval Britain, Amy Rose takes the place of the beautiful mystic. Viviean is Arthur’s lover, rather than Guinevere, as Arthur knew she loved Lancelot. Viviean is responsible for bringing about many prophecies, but she holds a dark one close to her heart. The prophecy tells of the end of Camelot, a great treason, Arthur and Lancelot dueling, and Bedivere being the last knight save Percival and Galahad.
