"I do not waste my teachings on the weak."
-Adas

Adas was King of Korriban and the Sith in a reign that lasted nearly three hundred years. He was large for his species, his skin was unusually charcoal-colored, and he was raised as a chosen being from his youth. Encasing himself in ebon armor, he wielded a massive battle-ax, and became a master of Sith magic. Circa 28,000 BBY, Adas united the disparate nations of Korriban in a series of bloody conflicts, eventually solidifying himself as the sole leader of his people.

The Sith hailed Adas as the Sith'ari, or "Overlord." The commonly held belief was that he was invincible, and that his reign would be eternal. Circa 27,700 BBY, Rakatans from the Infinite Empire arrived on Korriban, and taught Adas how to harness the technology of holocrons. Adas created one of these devices, but soon realized that the new arrivals were attempting to conquer Korriban. He took his battle-ax to the aliens, and with his people at his side, drove them off. In doing so, he lost his life.

Adas's influence, however, would continue for many years following his death. His holocron, lost on Ashas Ree during the Great Hyperspace War, would later be found by fallen Jedi Knight Freedon Nadd, who used Adas's teachings to subjugate and rule Onderon. When that planet cast off the yoke of Sith oppression in 4,000 BBY, the Jedi attempted to hide the holocron, so that it would not fall into the wrong hands. For nearly four thousand years it remained safely hidden on Kodai, but was retrieved in the years prior to the Clone Wars. Murder was committed several times in attempts to gain control of the holocron, and it was eventually returned to Korriban while in the possession of Dark Lady of the Sith Lumiya.
