The Oneironaut's Odyssey

KOTOR2 = Star Wars Knights of the Old Republic II: Sith Lords

Dream - KOTOR2
The start is a bit fuzzy, kind of resembles the forest world from Star Wars 7. I recall running onto a large ship as a battle was taking place. Later on I'm on Peragus II mining facility from the Star Wars game KOTOR2 (google it) and I've just beaten the bad guy leader. There was some dream-forged history about how this bad guy had been beaten before and had been rescued (like Palpatine rescue Anakin style or something) and he'd come back to get revenge. We're in the mining tunnels which are really hot and I've just cleaved him in two (possibly with a lightsaber?). I look at his body and see the modifications made to his brain, there's mechanical implants used to enhance his memory capability (some similarity to the protocol assassin droid in KOTOR2) and another implant which can control him. From this I gather that there has to be someone who was control the Sith but I don't know who.

I probably shouldn't have stayed up so late playing KOTOR2
