Did a search for a similar topic, didn't find one. Thought it might be fun to place our bets. I figure we'll at least attempt to restrict it to just the really essential characters. Have at it.
Live:
Kellhus -- This one's weird. Even though I don't really think he'll technically live through TUC, I also don't believe that will be the end of the character either, per se (becoming a god or something, etc.).
Achamian -- I think he's destined to make it until the end of the series.
Proyas -- Much like Akka, I think he's going to see it mostly through to the end.
Sorweel -- A tough one for me. I could easily see him dying in some significant way in TUC, but at the same time it would also be great to see him fifteen or twenty years from now, and he has a lot of potential to grow as a character. It's a tough call though, because his story could really go anywhere at this point.
Kelmomas -- I think this little rascal's going to make it out just fine, and likely end up becoming one hell of a villainous adult in the final series.
Die:
Esmi -- I personally think the WLW "predictions" are mostly true, so I think she'll be done for by the end of TUC. I'm not really sure where else her character has to go beyond that anyway.
Serwa & Moenghus -- Even if Sorweel survives, something tells me these two are doomed. Though I'd sooner bet Serwa making it out alive than I would Little Moe (and I'd like Serwa to live if only to have a strong female character that isn't a whore, slave, or concubine).
Mimara -- Another tough one. I definitely don't want her to die, but I do feel like there's a possibility of her perishing in childbirth (or soon after), forcing Akka to raise the child alone, thus becoming the sort of ultimate teacher: a parent. The only thing holding me back is what exactly the Judging-Eye's purpose in the story is. It seems like something that could become very integral to the end of the series, but it's also possible she may pass her gift on to the baby.
Fanayal -- I think he'll go down in TUC, with his power-base being taken over by Psatma, and thus Yatwer (and possibly Meppa).
I feel like I'm missing a big player or two, but I'm sure you guys will point them out.
