@E. L.Knight a thousand apologizes, I didn't realize that I had a task (or earned prestige) I removed my prestige and you can find my task. Please note that due to my lack of preparation I didn't have much time to study so I had to choose the first Sith that came to mind. Darth Revan: savior, conqueror, hero villain. Revan played pivotal roles in both the Jedi and Sith campaigns. However since Disney assumed control of Lucasfilm Darth Revan has not been canon. Fitting him into canon may not be as hard as it sounds though. Revan lived thousands of years before the rise of the Galactic Empire (the most cluttered time in canon) so he wouldn't mess with any timeline. Revan in fact makes current canon make more sense. He revives the Sith Empire and rebuilds the Sith Academy -updating the archives that Palpatine would later investigate to further his dark powers. Revan also helps grow the knowledge of the dark side powers which would eventually make more and more Sith (even Vader and Sidious) all that more powerful giving further reason of Palpatines immense power. So that is my entire non-preposterous synopsis of Darth Revan in currenct canon.
