I posted this in another thread but got no answer so I guess it can go here.

But I saw the last area as 5 Stages of Grief? (Just not in order.)

The Dragons: Depression. They sought reason to no longer go on, give up, and die as there was no star that would have them and they couldn't continue on in that place.
The Ea: Acceptance (Futility?) Full out wanted to die because they saw what the future would bring for the universe itself, accepted there was nothing that could be done and wanted you to accept it to.
Omicrons: I want to say Denial, as they were in denial that they could ever find purpose again, or a reason to live, and thus would stagnate until death.

The last two I'm unsure. I think with the gone civilization it was Bargaining, since you're meant to argue with Meteion.

For Anger though, I'm lost unless it was Emet and Hyth's anger in the last area. But that's a stretch. I may have them mixed, but there was definitely the 5 stages there in places.
