Adas
this ancient Sith King was the gatekeeper of the Sith holocron used by the leader of Onderon, some 4,000 years before the Battle of Yavin. Adas was a huge man who had used the power of the Dark Side of the Force to conquer his homeworld some 24,000 years before the Great Sith War. Sith scholars of the period believed that Adas created the holocron more as a testament to his achievements than as a teaching device.
