Vitiate

""My ascendance is inevitable. A day, a year, a millennium, it matters not. I hold the patience of stone and the will of stars. Your striving is insignificant. Let your death be the same.""

- Vitiate

Tenebrae, also known as Vitiate to Nathema, the Sith Emperor to the Sith Empire, and Valkorion to the Eternal Empire, was a Dark Lord of the Sith who reconstituted the Sith Empire after the Great Hyperspace War and went on to rule it for more than a millennium. He is the primary antagonist of the Jedi Knight Storyline and the overall main antagonist of Star Wars: The Old Republic, as well as its expansion pack, Knights of the Eternal Throne.

Powers and Abilities
Even as a child, Vitiate possessed immense strength in the Force, and his abilities began to manifest themselves at the age of six. He used his newfound powers to snap his adoptive father's neck with a thought, and tortured his mother with the Force for months while feeding on her fear and pain. As his powers grew, Vitiate continued to gorge himself on the fear and suffering of those whom he tortured in public executions. When he confronted the Sith Emperor.

Vitiate's power at the age of thirteen was great enough for Marka Ragnos to acknowledge the teenager's strength and grant him the title of Lord Vitiate. Vitiate soon gained a reputation as a scholar, spending much of the next century studying the secrets of the dark side. He soon gained an immense knowledge of Sith sorcery, becoming one of the most powerful practitioners of both Sith magic and alchemy, and devised complex rituals to warp life itself. Another one of Vitiate's specialties was in the domination of his opponent's minds, as he was able to dominate the minds of eight thousand Sith Lords and bind them to his will.

He then used their combined power to perform the most complex ritual of Sith magic ever performed, ripping the Force from the entire planet of Nathema and absorbing the combined life force of every living thing on the surface. Lord Scourge suspected that Vitiate had not only absorbed the lives of those who had died in the ritual, but was in fact feeding off their spirits to sustain his own throughout the centuries that followed.
