I think maybe she pointed into the far future, to Chancellor/Emperor Palpatine. he betrayed the republic cause he was hiding his identity, just like Kreia did. So i think it could be possibly Palpatine. Why else would she mention the fall of the republic, that would take millenia. And a milenia is 1000 years as you now, and the events of kotor 2 were about 4000 years before the rise of darth vader. Does someone see a link here? Cause i do!
