if i was one of the strongest sith in the galaxy (which, according to your story, you are) and i had been frozen away for 5 years, i think i would want to find my wife before i brought down a couple homicidal siblings controlling a droid army, especially since, as the new story states, the republic and empire have entered into a wary truce with the zakuul... so where the hell is jaesa and/or vette???
quinn can stay gone, but i'm still very disappointed there isn't a little side quest where i can shoot his *** out a damn airlock.
