Intersting bit there, but I dont agree with that conclusions. It is, I think, an after effect of the Cants of Compulsion. She felt that Aurang's thoughts where her own, his desires her, and so when she remembers the incident it appears that his soul inhabited hers, whereas it was really just his memories and passions.
As for chorae, we know there is something more to them when Mimara wields then through the Judging Eye. She did something, as far as Akka knew, that was entirely impossible, i.e unique and unprecedented. Not something other's could accomplish - especially someone like Moenghus so deeply rooted in reality, and also not having the JE.
Yea, I understand its a result of the cants of compulsion. But, doesn't Kellhus say that Aurang didn't want to posses Esme any longer than need be, because more of his memories would have went to Esme (or something like that).
As for the chorae, remeber when Cnaüir touches Moe with it, he says it seems as if the God is loooking at him through Moe's eyes. Mimara sees that it is try a Tear of God. I just believe there is more there. Can I give you a explanation of why? No. But, man I really like @the merchant's idea that the creation of chorae might involve a soul, and would really make sense, since as he said the each have different flavors. We don't know how a soul is trapped in a Waathi Doll, but if souls are connected to chorae that would seem very plausible way to make a Waathi Doll.
As for Kellhus extracting info from skin-spies, I don't remeber him getting any useful info from them. If someone could quote that for me, I'd appreciate it. Because, I can't recall that to be the case.
I reread that bit about Moe and Cnauir at the end of TTT the other day and that stuck out to me too. I think this is the only time we have read a description of someone choraed up close, and I assume that this is just a description of the process as seen from a foot away. I think the bit about a "god" is just how Cnauir, who is completely obsessed with Moe (and I daresay worships him in some way) would think about it. I think it was poetic license on Bakker's part and not meant as some sort of clue.
As for Kellhus interrogating skin spies, MSJ was right and I was wrong in our earlier posts. I found a part in TJE where they have captured the black-skinned skin spy, and it is mentioned that without Kellhus there, they wouldn't be able to get anything useful out of it. Since Maithanet is standing right beside Esmi when she thinks this, then the implication is that Kellhus CAN get information from them and Maithanet cannot. Therefore, it seems unlikely that Maithanet was able to find out on his own that Simas was a skin spy at the end of TTT. However, there is always the possibility that this was a mistake by Bakker.
