TGO. Very last entry of the book is one of Akka's dreams. Nayu is led under the IF and it ends with him standing in front of the Carapace. Bakker doesn't get any clearer than that.
This is the scene I was talking about, and it doesn't show the event itself. I did read it as him being put into the Carapace, of course, but my point is, it wasn't shown. I would've been interested in the perspective of an Insertant at the moment of Insertion, however unreliable it may be.
It shows us specifically Kellhus and say he is the end of the world. Yes interpretative. But, he played a part in the rise of the No-God.
I'm completely unsure even about it being Kellhus shown. Without further clarification (or at least corroboration) that whole dream just seems counterproductive to draw conclusions from. I can base hundreds of plausible theories on it, not just one. But the fact remains, the dream doesn't give any evidence, it contradicts the existing body of it.
But, it's not any historical dream or that any other Mandate has dreamed. Its not a usual dream.
We don't know that. The origin of Celmomian prophecy as it's recorded in history is unknown. We also have no idea what Seswatha's Dreams actually are.
whether you find it convienent to clarify these things in the text, imo, is your way of hand waving the proof away.
This works both ways. I don't see any proof, I see something unknown and unexplained with unclear agenda at play here. You have a theory about it, and theories are good, but it's only one theory where hundreds of the same level of plausibility can be offered. Why only focus on this one? I don't offer other theories only because I consider them pure speculation, without a shred of hard evidence behind it, so I can't prove anything, and thus there are no grounds for discussion.
Kellhus wanted to know about the dreams, he didn't do it and Akka denied him and Sacarress out of spite. Yes it's the only neatly tied bow in the whole series, with textual evidence and confirmation to back it up. What more do you want?
Kellhus's perspective on metaphysics, more information about Seswatha's Dreams, and other accounts of said dreams (even normal ones) would be a good start.
Right now it's an unknown of Ajokli's level of importance. And it's quite specifically not elaborated upon in the narrative, just as Ajokli was.
