Question
What is the nature of No-God? What is contained in the Carapace?
Prediction
No-God is re-animated head of Cu'jara-Cinmoi, probably with his soul bound to it, in a confused returned-from-the-dead state, hence the WHAT AM I? question No-God always asks. TTT Glossary description of Cu'jara-Cinmoi death "... fought his way to Cu'jara-Cinmoi's position, but found only his headless body." was a giant Chekhov's Head (heh) for me - why mention such a specific detail, if it's irrelevant? And the recent excerpt from Grimdark Magazine also mentions "There is a head on a pole behind you." - as it describes Kellhus visiting Outside.
Prediction
Moenghus the Elder didn't die at the end of TTT. Rather he spoke to Kellhus from a secure undisclosed location, remotely controlling another Cishaurim's body made to look similar to his own as a precaution. It was mentioned previously that Moenghus was bad at most Psukhe practices requiring faith & passion, but very good at those requiring subtlety and intellect - such as his ability to send dreams to Dunyain at Ishual or to have Skauras speak with Xerius via his own body. After Kellhus left, and his sorcerous puppet died at the hand of Cnaiur, Moegnhus suffered a profound feedback shock, but also came to believe Kellhus's arguments and gained tremendous amount of faith becoming Meppa.
