SPOILERS ALERT! Please all correct me if im wrong, but i have read that 'time wise' the republic flashpoint were revan is saved is before the empire flashpoint were he is 'killed' or more likley flees. I have however ***MAJOR SPOILERS*** noticed that after seeing many class endings, that the emperor is killed by jedi knights with the aid of the emperors wrath, but in sith warrior he is alive and the player is the emps wrath. Again, correct me please if im wrong, but as is with ALL GAMES LIKE THIS, with multiple different endings, there is always one that will be canon. And, as ALWAYS with ALL star wars games, the light side ending is always the TRUE STORYLINE. And seeing as though all the Republic side endings tie well together, this would lead me to beleive that revan is not dead, we do not know what has happened to him, only time will tell. As well as this, the emperor is dead and the empire will die out.
