Darth Revan Reborn's Starforge Empire vs. Vitiate's True Sith Empire
Assume Darkside Endings for KotOR 1 and 2 are canon for this thread.
Revan and Bastila rule as the two top Sith (or Dark Jedi since Revan would have been aware of the true Sith), and he begins mobilizing his empire for Vitiate.
Since the events of "Revan" no longer happen, Vitiate isn't held back and launches an attack about ten years after the events of Kotor 2.
The top Dark Jedi in Revan's Empire would be himself, Bastila, and Dark Exile, who has some pretty mean feats (taking down the Jedi Masters in single combat, including Kavar, for one).
Who wins in an all-out galactic war? Does Revan's empire hold up better than the Republic did 300 years later in the standard canon?
If it came down to a battle of the leaders, does Darth Revan with a honed StarForge amp and a full embrace of the dark side rival Vitiate?
