Darth Revan vs. Kyp Durron and Kyle Katarn

Again correct me if I'm wrong but from what we know of Darth Plagueis, he was a sith alchemist or just a practitioner of Sith magic since he learned how to cheat death.. Assuming Palpatine wasn't lying, Plagueis would have been the one to bring back the ancient sith magic.

Or not, since Palpatine describes it as knowledge of the Dark Side. This is all assuming Palpatine didn't simply make him up, of course.

Gotcha.
