I never said Revan was part of the Sith Empire. At this point Vitiate was hiding and “influencing” and thus the Revan story begins. I’m meerly pointing out that indeed there was another Empire but the Sith Empire lived on way after Malak and still ran by vitiate along side the Eternal Empire.
But thanks for correcting me on the Sith triumvriate. I havant done to greata home work there and i still havant gotten around to finishing kotor 2. Got stuck fighting the jedi masters. (Not leveling my character properly i imagine and gave up)
