Sauron
From t2twiki
The great unseen evil of Arda, Sauron is the force behind the current War. His forces seek the One Ring, which he forged long ago, and have laid siege to the cities of the Free Peoples. The Evil Races serve his cause personally.
[edit] History
Sauron was a Maiar spirit seduced to evil by Melkor at the dawn of history. He served as Melkor's lieutenant throughout the First Age and took on the role of The Enemy when his master was cast out of Arda. During the Second Age, after creating the Ring, he was responsible for the destruction of Eregion and, eventually, Numenor. Although he was discorporated during Numenor's fall and again during the War of the Last Alliance, he has taken shape once more.
