Adas

Adas was a Sith warlord who lived circa 28,000 BBY, long before the exiled Dark Jedi of the Hundred Year Darkness conquered his species. He used his knowledge of the dark side of the Force to conquer and subjugate his homeworld, which he ruled as king.

Adas was clad in signature black armor, attire that matched the dark hue of his own skin. His mastery of Sith magic and reputation of conquest led his people to regard him as a near-immortal figure.

By the time the Rakata came to conquer Korriban, Adas was over three centuries old, and, although they taught him the secrets of constructing the pyramidal Sith holocron, Adas knew the invaders were bent on conquest. He led the Sith race to victory over the Rakatan invaders, but at the cost of his own life.

Around 4,010 BBY, his Sith holocron was uncovered by Queen Amanoa of Onderon, who learned all the stored secrets. The holocron was then passed to her apprentice Novar to teach Sith initiates. The Gatekeeper of Adas's holocron, however, had an unique personality that it could turn down the user's request or even threaten its user. King Adas's holocron eventually found its way into House Pelagia's holocron library and subsequently liberated by Sir Nevil Tritum of the Mecrosa Order during the Great Jedi Purge. Following the Battle of Endor the order gave the holocron to Lumiya.

Behind the scenes

 * In the Tales of the Jedi Companion, Ood Bnar says Adas lived "more than two dozen millennia ago." The Old Sith Empire was established by fallen Jedi Knights around 6,900 BBY, which would preclude Adas having been part of this regime.
 * Evil Never Dies: The Sith Dynasties retconned Adas as a ruler (circa the time of Ood Bnar's statements) of the Sith species, rather than a Sith Lord.
 * A holocron flashback in Tales of the Jedi: Knights of the Old Republic depicts what is labeled by Ood Bnar as a Dark Jedi garbed in black armor. This may be Adas, despite the fact he appears to be wielding a lightsaber in the vision. However, Evil Never Dies author Abel G. Peña said  that he did not specifically base Adas on the Holocron Dark Jedi, and while they might be the same, he didn't consider them to be.
