If you'll notice he tries to drain the PC of the Force or life force which ever you wish to call it, during the battle which exhausts him. That is why he is so easy to kill. If you talk to Visas enough she says that when her master killed everything on Katarr, her homeplanet, she was the only one left alive. That is why he didn't kill her. It's obvious to me that he was using her to find force sensitives for him to feed off of with her special gifts. Also Nihilis is a failed experiment of Kriea's I think perhaps either he was at Malachor and the same thing happened to him that happened to the Exile or Kriea attempted to recreate what happened to the exile but failed.
Another of Kriea's failures in the fact that he didn't kill her not once but twice. The reason... he wants to be excepted by Kriea and has failed because he could not kill her. So he falls back into the hole of being her student instead of becoming the master.
Atris... when you first meet her she assumes you are there to kiss her butt and beg for forgiveness. She says she is the last of the Jedi when she knows very well that Vrook, Kavar and company are still alive. Atris also is the one that leaked your name to galaxy that you were the "last" of the Jedi. When you talk to HK-50 at the beginning of the game he mentions that it was him that told everyone that you were a Jedi and had been in Exile. There is a line there that the PC can use that says that that information would not be in the coreward databases but only in the Jedi archives and who is the mistress of the Archives? Atris. In the final battle with Atris she says that she released your name to the public so that you would lure the Sith out of hiding so she could kill them so that she could be the hero of the galaxy this time not you or Revan. Also I have my suspicions that it was Atris that lured Nihilus to Katarr not just the Jedi there. If you tell any of the Jedi Masters that Atris is on Telos they all say they thought she had gone to Katarr.
Actually no. Bao-Dur says if your seeing this we've returned to Malachor V. And askes the remote to activate the mass shadow generator. Obviously you did not gain enough influence with Bao-Dur or did not train him as a Jedi because he tells you he created what destroyed Malachor and that the exile gave to order to use it. As for Go-To and Remote if the Mass shadow generator blow the planet then Remote overroad Go-To reprogramming.
Okay this I have no clue about. The only thing I can think is that she followed me at least to the door and then realized this was out of her league and went back to the Ebon Hawk.
This I think was to show you the Ebon Hawk managed the get free of that crevice it was wedged in.
It's proof of how arrogant the Jedi Masters are and it's a betrayal. Which is a very obvious theme through out this game. Kreia was betrayed by Sion and Nihilus. Atton betrayed the republic by joining with Revan and Malak after the Mandalorian wars, etc. They do not fully understand what happened to the Exile and instead of helping him/her reconnect fully to the Force and understand what happened instead the kick you out a second time. Kriea says you brings truth and they condemn it. They fear you because you lived without the Force which they believe is impossible.
Canderous says that the Sith came to the Mandalorians with an offer to fight a worthy enemy in a battle that would be remembered for ever. These were not Revan and Malak's Sith were talking about here these are the real Sith. Revan and Malak were just Jedi who followed the Sith path. Well no matter what you choose you have to leave Malachor V, don't you?
Kriea talks constantly of manipulation and betrayal. She despises the Force and would like to see it's end. Which is what she sees in the Exile. However, along the way she sees that you have the potential to be greater than her first (who I assume she means Revan). As to the force bond ask anyone, Vrook, Kavar, Disciple and they will tell you that they have never, ever heard of a force bond being lethal. I have also heard that bonds end with some act of betrayal. Which Kriea betrayed you did she not? And I would believe everything that Kreia told Atris because Kreia is a manipulative old witch. It could be she told Atris all those thing just to get you to follow her to Malachor V.
You tried to save the galaxy but for once failed.
