Darth Bane

Fictional character in the Star Wars Expanded Universe. He is first mentioned in the novelization of Star Wars Episode I: The Phantom Menace, and is thereafter consistently referenced in Expanded Universe material. He is a major antagonist in the Jedi vs. Sith comic book series, and the protagonist of the novels Darth Bane: Path of Destruction, Darth Bane: Rule of Two and Darth Bane: Dynasty of Evil. Bane was also the one who established the "Rule of Two" for the Sith Lords: a master and an apprentice can be the only sith in the galaxy at one time.

In the Star Wars universe, Darth Bane is an extremely powerful Sith Lord who lived 1,000 years before the timeline of the films. He resurrects the Sith Order after destroying what he saw as a corrupted empire, with power diluted among too many individuals, and institutes the "Rule of Two" philosophy that would aid it in taking over the galaxy 1,000 years later in Star Wars Episode III: Revenge of the Sith.
