Ari is a Druidsorcerer, and an ally of Morgana Pendragon during her war against Camelot. Ari is brought before Morgana, who forces him to use magic which he does, and then Morgana has him held down. Ari begs her to stop, but she places a magical creature on him which drains his magic away. Morgana then forces Ari to use magic again, and he does, being threatened about the well being of his family, but nothing happens, revealing that he has been robbed of his magic. Later, Mordred explains to her that she lost a powerful ally, but she replies that now she knows that they can win the war.
