Trask Ulgo, Dark Lord of the Sith.
Thought to have been killed by Bandon on the Endar Spire, Ulgo was spared by Bandon mainly because of his strength in the Force. Indeed, so powerful was he that he was able to hold off Bandon with a simple vibroblade and even proceeding to cut him across the arm. Bandon, recognizing his power, taught him the ways of the Dark Side, and plotted to use him against his master, Darth Malak. Unfortunately, Bandon was killed by Revan, and Ulgo's heart was filled with revenge.
Fleeing to the Outer Regions, Ulgo became a Sith Lord by the name of Darth Trask. He is exceptionally skilled with a lightsaber, and wears a Republic uniform under his clothes, attesting to the devotion with which he once served the Republic. He is currently on the quest to find Revan and avenge his master's death...
