True Sith

The "True Sith" were a shadowy and largely unknown order of Dark Side users that according to Kreia, had been in existance for "tens of thousands of years," and were silently waiting in the Unknown Regions, during the time of the Jedi Civil War.

According to Kreia, the so-called "True Sith" were millenia older than the Old Sith Empire. She and Revan believed that it was they who goaded the Mandalorians into attacking the Republic. She stated that both Malachor V and the graveyard planet Korriban had once been planets held at the edges of that mysterious empire, and that while these "true Sith" had forgotten those ancient worlds of the Dark Side, they would remember.

Following the Jedi Civil War, Revan vanished from known space, supposedly to fight this order.

Behind the Scenes
There is a great deal of speculation as to how this Sith Empire could have possibly pre-dated the Hundred-Year Darkness. This is fueled by the existance of Adas, a Sith Lord who lived more than twenty thousand years before the Dark Jedi made contact with the natives of Korriban and Ziost.
