Sauron from The Lord of the Rings
The Necromancer, Lord of Mordor, the all-seeing Eye, Morgoth's servant, and the true Lord of the
rings, Sauron dons many guises as the principle enemy of the free peoples of Middle-Earth. In Tolkien's world, Sauron started out as an angelic being, one of the Maiar, created by Eru himself.
