I don't think we heard anything about what happened to Egeanin/Leilwin, or to Baye Domon either. Probably unceremoniously bashed over the head by trollocs while Egwene was busy turning into a pillar of crystal.
The "sheathing the sword" manoeuvre is one that Lan teaches Rand right at the very beginning - I do love how much Robert Jordan plays the long game - you let the enemy stab you in order to get them close with their guard down. The way it was described, it's for situations where it's more important that the enemy die than that you live.
I guess Demandred's one stab was not fatal. (I also assume Lan got magical healing afterwards).
I think Egwene is a crystal pillar too - there was no mention of a body.
I actually quite liked Sanderson's books - they moved a lot faster. I hear there is a lot of material for prequels, but I don't know if it's in good enough shape for someone who is not Robert Jordan to write them.
Actually in my re-read I felt that book 11 was where things started moving again, and that was RJ, so maybe it would have happened anyway.
Okay - Egwene: it was Taim who turned to crystal when she used the opposite to balefire weave. I think she felt Gawaine go and pulled more than she should have using a sa'angreal or angreal and so burnt herself out healing all the balefire cracks.
I don't know about Cadsuane TBH, she strikes me as the type of person so much an Aes Sedai that she'd rather die a couple of hundred years earlier as an Aes Sedai than give that up.
Cadsuane is one of the oldest Aes Sedai in recent times, right? I guess she'll want to live a longer life so maybe she would be keen on the whole release-the-oaths-and-live-a-few-hundred-more-years thing.
I think Nynaeve will be involved in carrying on the kin. Whether Cadsuane is keen or not. Not really sure with Egwene. I've just started a re-read and it's so different with the knowledge of the the last book, I'm amazed at how different the characters are. I kind of wish there was more Mat but didn't like the way Sanderson wrote him. I'm also ebing reminded of what a selfish little shit he could be (despite him being one of my favourite characters)
Only on book one and none of the 'sniffing' etc has started yet
