(sigh) The True Sith are not in K2. They weren't meant to be. You get vague references to them in conversation, mostly in the end. That's it. They were meant to be the central focus in K3 (if it ever comes out). The only reason the True Sith were mentioned was so that they would have something to focus K3 on and allow for a continuation of the current story. And the True Sith are beyond the outer rim in the "unkown regions", but you get no specific location. I guess you have to find them in K3.
