Avatar Means to cross, pass over. (Hindoo Myth.) The descent of a deity to earth, and his incarnation as a man or an animal; -- chiefly associated with the incarnations of Vishnu. The Isle of the Avatar was discovered during the Fourth Age (as related in Quest of the Avatar), at the climax of the Avatar's quest. The Stranger from Another World, who came to Britannia in answer to Lord British's summons, completed the Test of the Eight Virtues and became the Avatar --- the embodiment of the pure axiom of life.
