Darth Nebulous

Darth Nebulous was a Force-sensitive Zabrak male and Dark Lord of the Sith as a member of the Sith Triumvirate which ruled over the new Sith Empire. Originally a member of a Nightbrother tribe, Nebulous went through brutal training as a warrior skilled in multiple forms of combat. Nebulous became a Sith Apprentice under the self-proclaimed Dark Lord of the Sith Darth Xylith, and was extensively and brutally trained in the ways of the Dark Side of the Force. Nebulous grew immensely powerful, and later killed his master after learning he was training a new apprentice, who he took as his own, Darth Kaabal.
