Madness, I hadn't really thought about the ratio of deaths in Ishual and the Bakker-Moria. The dunyain would have to work overtime to catch up with that and I don't know what purpose it would serve to characterize Ishual as a topoi-lite. I don't know if Kellhus would have noticed dunyain in atrithau because I think they would be the ones with the puppet strings in that set up - remain hidden while he's in town, play on some blindness they've conditioned him to have.
I can't shake the idea that Moe could have been in contact with Ishual all along, everything Kellhus reminices is deception on their part, he's the only one who got the dream, none of the old dunyain died for impurities, he was set in a group of young-uns where he would already start to feel a little special (answers the tree/war question right), manipulated by psuhke ALL ALONG. Nother Ishual revelation: the entire breeding stock is descended from the the Anasurimbor line! Kellhus is the only one told that his surname is Anasurimbor to give him that special, chosen feeling.
Atrithau has got to be something good, but I have no idea why it's status as 'anarcane' would have saved it in the first apocalypse. Isn't the NG supposed to be unsorcery in some sense? Must have been a weird place for a Mandate mission.
