All the ones after the novel are Voices, but after the Wrath and the Hero kill his Voices on Voss and Kaas respectively, he returns to his original body which was clearly on Yavin IV in one of the temples. Vitiate himself went there to scout the temples out, it is highly likely that this was the place the Hands referred to when they said he had returned to original form and was recuperating.
Well, we know for a fact Revan plans to put Vitiate back into a body. If Vitiate is already in a body on Yavin IV at this time, then it must have been destroyed, presumably by Revan. Every time a Voice dies, Vitiate's overall strength is depleted. Revan wanting to bring back Vitiate again indicates that, if Vitiate were to die again, he would be too weak to take another host and thus would fall into the void. My only issue, though, is that there's no indication Revan (or anyone on Yavin IV) ever killed a Voice, so I'm rather confused here. I assumed that it was the defeat by the Hero of Tython that pushed Vitiate to the final straw, not another Voice down.
Which temple? The Temple of Sacrifice or the Emperor's Sanctuary?
If the former, then what did Revan plan to do in the Emperor's Sanctuary after the Temple of Sacrifice was destroyed?
If the later, how would that work out? The Emperor reawakes on another side of Yavin IV and Revan teleports to the location to fight him?
I finished the expansion finally. I thought it was pretty great throughout. The final confrontation with Valkorion is perhaps the high-point of the entire game and is very satisfying. I liked that you can essentially just tell him "Oh, whatever gramps. Shut up." in the end. Also liked everyones disgust when he says he has no family.
Kind of wish there was a neutral option to become Empress but not be a dick about it. It feels odd that everyone was saying I should be Empress and looking forward to it and talking about how great and worthy of being Empress I was and then the only option to do it involved me dunking on everyone while people grimace.
Vaylin, Arcann, Senya and the Outlander come out looking very strong in this. Still need to figure things out but all their stock got raised, some considerably.
Valkorion is still godlike and is certainly the strongest Force User in history up to Luke imo.
Spoiler:
When he dies the shockwave through the Force is so strong Satele almost blacks out all the way on Coruscant.
After watching all the cutscenes, light and dark, I haven't seen Revan Ant.
It's a shame after all the whispers of originality, they went the predictable route and had Valkorion try to set the Outlander up to be his meatsuit.
All they would have needed to do to make it better was have that be the option only if the Outlander refused to take the throne as Valkorion's chosen heir.
