So, Kellhus's sword has indeed been ensorcelled, right? How else does he cut of Malowebi's head and manage to keep him alive? So Malowebi is destined to watch. Watch what exactly? When reading and Pstama said that was his destiny, I figured he would just switch sides to Kellhus and document the SA, like Akka did the First Holy War. Not the case. The head on a pole behind you is the best explanation I've heard so far. Or, he's just gonna be some dread standard that Kellhus keep with him at all times. I don't see that though, too easy, too cheap, to be something Bakker would do. I think you guys have hit the nail on the head with the head on a pole behind you.
So, Zuem is gonna come right over to Kellhus now, I would imagine. I figure in seeing Zuem sending ships to aid the Ordeal, as others have suggested. So, after the Ciphrang goes to Zuem to end the line of Zsoronga's family, do you think we'll see it go after Zsoronga himself? Interestingly enough, we didn't see him at all. And remember, he has Sorweel's chorae, and I have to believe that it will come into play at some point. Has to.
I don't think it's ensorcelled. I think this is the original sword he has always carried, in which case, it is Dunyain steel and the Dunyain had no knowledge of sorcery. I read the whole thing as something to do with the soul sticking with the body for a little while after death. It's really his soul that is seeing the transformation.
As far as the head on the pole, Malowebi is as good an explanation as any I have heard (and we have seen that time is note necessarily a set thing in Earwa). I can't see him heading up to Golgotterath to go after Zsoronga, but maybe he will. If anything could make it through the sranc-infested wilderness alone, it's an M type Ciphrang.
