Hmm, I was thinking a lot about those mysterious enemies (that will be probably battled in KotOR III). Who do you think they are?
Canderous mentions them in KotOR 1, saying that they encouraged the Mandalorians to start a war against the Republic, a war that will be remembered for centuries. He said that they had returned to their empire after the start of the war.
-> what empire, what real Sith?
The followers of Exar Kun, some years before the events in KotOR 1, described themselves as the Sith. Mandalorians fought aside Kun's forces in the Sith War, but were decimated (Mandalore was killed by a beast on Dxun). Kun was also defeated and so all his forces. Question is... who made the remnants of the Mandalorians fight against the Republic for the second time?
Or maybe something from the ancient (Naga Sadow, Ludo Kressh) Sith Empire "survived" and they are those "real Sith", but why then Kun says: "The Sith empire will rise again" - he wants to ressurect it...
What is more, the ancient Sith Empire's central planet was Korriban, so te "real Sith" empire (KotOR II) can't be located there, since this part of the galaxy has been already explored.
Any ideas?
