Sauron

Sauron is the Lord of the Rings and the second Dark Lord, originally a servant and Maia of the first dark Lord Morgoth.

Origin
Sauron was originally chief among Aule's people. Before entering Ea, however, Morgoth seduced him, and his name became infamous among the Maiar. His downfall at the end of the Third Age of Middle-earth is described in the saga entitled The Lord of the Rings.
