Forum:KB:about the Sith Empire

In the events of Kotor 2, surely the Sith Emperor must have sensed Darth Nihilus through the Force. If Darth Nihilus had succeeded in eliminating the last remaining Jedi he would have then turned on his own Sith and fed on them, and then he would have traveled to Dromuund Kaas and fed on the thousands of Sith force-sentients that lived there?

Was Vitiate worried about this? Was he interested in acquiring Nihilus' power? How would have he defended himself if Darth Nihilus had shown up at his gate and decided to devour al life in the "true" Sith Empire"?

Thank you very much, dear Wookieepedians
