Man, had to dig deep to find this wildly-off-track thread.

I've been wondering about the possibility of the WLW, at some point in the future, taking Sorweel's place, the way he took the assassin's place. It's said that Yatwer is
"positioning" him. I could see this as literally creating a position which the WLW could fill.
My first minor hold up here is whether or not Sorweel will ever even see Kell again. My theory there is that after they take Dagliash, the Niom will be fulfilled and the three will ride with the nonmen to the Ordeal. I don't know if there's anything that necessarily precludes this. Except for whatever crazy shit is actually going on in Ishterebinth.
My
main hold up here is that Kellhus knows what Sorweel looks like, and knew this before Porsparian blessed Sorweel. So there's no fooling him there.
He does not know what the WLW looks like, nor do we know what his and Yatwer's powers are in regards to shaping his face or creating an illusion (point against: he certainly made no effort to look like the assassin, even though his hair was radically different from those kinds of assassins and could have alerted Esmenet). Not that Kellhus is the type to 'let down his guard', but if he were, it might be while meeting with or individually greeting the Believer Kings, perhaps after a long and arduous battle.
Am I missing anything that makes this impossible or unlikely? Honestly I can barely even get behind the idea of someone
killing Kell, surprise sword-breaking or not, but the WLW is 1 for 1 on the amazingly smooth killing of a half Dunyain at least.
