Oh, and Sum Yung Guy, there's no such thing as a Dark Jedi in regular SW continuity. That's a category that was created for RPG purposes, and is not a creation of George Lucas'. If it's not created by Lucas, it's doesn't exist in the prime continuity. Count Dooku was a Sith Lord. His other name in the film is Darth Tyranus, and the prefix Darth is used only by the Sith.
