I have two queries about the ending, I understand most now but I have a couple of questions left.
1. As you have a force bond with Kreia you must go to malachor or she will kill herself and you will die, however how come when you eventualy kill her at the end you survive.
2. I got Kreia's vision of her betrayel by Sion and Nihluswith a planet or two to go, I was playing as LS so how come, if Kreia was admitting to being a sith lord could I not challenge her to a duel. All you could do was carry on, trying to save the galaxy with a sith lord as your master.
