Is it possible for the trolls to ascend still? (i'm asking because a friend proposed the idea that if a session merged that the other aspects for the other players would show up inside derse and prospit of the game they are joining...)

I mean… Likely not? They’re not part of a Session with Quest Beds and Dreamselves anymore, chances are they won’t be able to but honestly who knows, there may be a Third Bed at Earth’s Core for all we know.
