Yeah... i can't stand being a Consular anymore.... its just too damn easy, i really prefer being able to get up close and personal with a lightsaber and chop the shizz out of people.
Zayne Carrick could easily be Nihilus from his prophecy as the "World-Destroyer." Although I do find it doubtful, I think he would be better set as the Exile. He was said to be reckless and always leaving a destruction in his wake.
But unfortunately the Exile is supposed to be a female in the EU continuity. Read part 4.1 at http://starwars.wikia.com/wiki/The_Exile
Well.... technically Nihilus shouldnt have ever died, he could have just kept feeding on your companions... but nvm.... Carrick could easily be him... and Kreia could be that one Jedi Master Arren Kae... Kae+Traya=Kreia... and lots of other stuff, let me post a link about it.... its the Behind the Scenes part http://starwars.wikia.com/wiki/Arren_Kae
HOwever looking again...
Evidence put forward by supporters of this theory includes:
The fact that both Kae and Kreia are referenced as being Revan's first and last master.
Both are said to have been sought out by Revan before he left known space for the same last knowledge to be imparted.
Atris's exclamation of "Kreia? That is not her name".
The odd, almost coy, way in which Kreia speaks of her.
The fact that the Jedi Exile has no knowledge of her at all, despite her being a prominent Jedi Knight/Master who was sentenced to exile and fought in the Mandalorian Wars, hints that Kreia might also be causing her to forget as she is the other Jedi Masters she comes across.
Atton says that Kreia was once beautiful, and hard living creates a face like hers and Kreia herself says that Kae was beautiful and strong in the Force.
Kreia's name is pronounced as if it were a portmanteau of the names "Kae" and "Traya." This is possibly in keeping with the character's personality. Given that she turned her back on both the Jedi Council and the Sith; and combining her name as a Jedi (Kae) with her name as a Sith (Traya), instead embracing the Grey Philosophy.
If your character follows the light side, you will meet Zez-Kai Ell, Vrook and Kavar. Before they try to strip you from the Force, Kreia storms in, and with shock Master Kavar says, "I thought you died in the Mandalorian Wars." Kae also fought in the Mandalorian Wars and it was believed that she had died.
There are cutscenes with Mical and Kreia where she reveals herself to him, and he recognizes her, then she makes him forget it.
