Darth Revan

Revan, renowned as "The Revanchist" and dreaded as the Sith Lord Darth Revan, was an eminent Jedi Knigt turned conquering Dark Lord of the Sith until, stripped of his true persona, he returned to the crumbling Jedi Order and helped defeat the Sith Empire he had established. A Human male, and acknowledged as a very gifted and powerful Force-sensitive pupil, he was trained as a Padawan by Kreia and a number of other Jedi Masters, both on Coruscant and at the Jedi Enclave on Dantooine.
