Darth Erebos was a Human Dark Lord of the Sith from the planet Alderaan. Becoming Dark Lord in his late 30's, Erebos led an attack on the Jedi on every one of their worlds. Each one of the attacks would be thwarted. Erebos would kill all but one member of the Jedi council before Filose Naj came to the rescue and killed the Dark Lord, decapitating him.
