TrueSith

Imho it is quite evident that this game is missing quite some content originaly planned. Too many loose/rushed ends. Basicly everything is explained, but I was not satisfied. What are Nihilus exact origins (Malakor I know...), did he share his fate with the exile but turned? This is implied but never really revealed. Where does the undead Sith Lord come from? He once was Kreias apprentice, like Revan.... What is Kreias whole story? Who send the assasin droids? What is Go-To
