I've gone through the game twice, once as darkside, witch left me with nothing but unanswerd questions and once as lightsided, witch made me aware off some strange remarks made by Kreia and the Jedi Council.
1. This new 'sith' threat does only exist since you are responsible for it (Malchor V destruction and sofort)
2. According to the council you are the cause of a new threat who absorbs the force from all living beings... so you must be killed to end this threat!! This makes you no different from what Darth Nihilus is !?
3. SPECULATION , you lose you're connection to the force on Malachor V, though you're forcepowers are not lost and start to live a life of their own as this darksided character Darth Nihilus (Nihil is latin for nothing). This could explain why you were the only jedi that did not turn darkside after the Mandolorian wars, you just casted it away from you physical body. Furthermore, this Darth Nihilus does not have a voice, does not have a face (even when you ask Visas to remove the facemask and ask her what she saw she gives a very cryptic answer, witch could mean there is no face beyond the mask)
4. Since most of us now allready know there has been some serious cutting in the end levels (about everything after final meeting on Dantooine) it seems to me that the only way that this Darth Nihilus seems to fit in the story, since now he does not have the smallest part in it, if not to give you some sort of extra battle, is that HE IS YOU and YOU ARE HIM, BOUNDED trough the FORCE.
THIS WOULD MAKE THAT THEY CREATE A SURPRISE AS BIG AS IN KOTOR ONE WHERE YOU FIND OUT THAT YOU ARE REVAN !! Sadly enough due to lack of time, Nihilus turend out to be nihil.....
Would this not explain why he is central to all promotion they made around the game??? BOXART, POSTERS, WALLPAPERS, etc......
