Sauron (or Þauron (Thauron); Quenya; IPA: [ˈsaʊron] or Vanyarin; IPA: [ˈθaʊron] - "The Abhorred"), the eponymous Lord of the Rings, was a fallen Maia, the creator of the One Ring, and the most trusted lieutenant of his master Melkor (Morgoth, the first Dark Lord). After Melkor's defeat in the First Age, Sauron became the second Dark Lord and strove to conquer Arda (Middle-earth), creating the Rings of Power for this purpose. In the Second Age, he was defeated in the War of the Last Alliance by the last line of defense: Elves and Men under kings Gil-galad and Elendil.
