Interesting. I went through the Journal of Gnost-Dural yesterday to get the actual years for the cinematics leading up to the game. There's a 13-year span between each event. Thirteen years before the game was the Sacking of Coruscant. Thirteen years before that was the Battle of Alderaan. Thirteen years before that was the arrival of the Sith at Korriban. The writers seem to like that number for some reason.
39 years? No wonder Malgus looks *********** horrible now. xD
