Sauron, the Necromancer - The Lord of the Rings: Tales of Middle-earth

Sauron is the title character and the main antagonist of J. R. R. Tolkien's The Lord of the Rings, where he rules the land of Mordor. He seeks to conquer Middle-earth using the power of the One Ring, which he has lost and attempts to recapture. In the same work, he is identified as the "Necromancer" of Tolkien's earlier novel The Hobbit. The Silmarillion describes him as the chief lieutenant of the first Dark Lord, Morgoth. Originally an angelic being, Sauron followed Morgoth in his rebellion against Eru Iluvatar, the supreme being in Tolkien's mythology. Sauron appears most often as "the Eye", as if disembodied.
