Finally finished the book last night!
The chapter arches slowly degrading really freaked me out, tbh. Although it was really cool seeing the Kaladin Herald icon at the end amid the rubble.
I was very surprised when Todium destroyed Kharbranth, for obvious reasons. I kept coming back to that and wondering whether Taravangian had truly given up on the only thing he truly wanted to be preserved. Well, he didn't, he put them in the Spiritual Realm, which I feel like I should have expected.
Kaladin and Szeth's entire story was the most wholesome thing in the entire book. When everyone else was dying and failing miserably at everything they did, going back to Kaladin, Szeth, and company was really a relief. I loved Kaladin playing the flute and just being happy, the little tidbit in the in-world text mentioning that Szeth got married and started a new life in Shinovar was super cute, and I got attached to 12124 incredibly fast, which makes sense considering he meets Sigzil (holding the Dawnshard) in Shadesmar, meaning he's almost certainly going to become Aux! Unfortunately, Kaladin's body is technically dead now, but personally I don't think it counts since he's a Herald now.
Jasnah really had it coming in Thaylen City. Don't get me wrong, I like Jasnah, but I do believe she needed that failure, and Taravangian was absolutely right about her. Hopefully she can reform her philosophy and hopefully all the suspicious things she did in the past won't harm her in the present any more than they already did.
It's a shame that Moash isn't dead yet, although I would have been fine with something like redemption, too. Unfortunately he barely appears, only doing to to kill poor Leyten and to force Sigzil to abandon his Windrunner oaths.
Venli winning back the Shattered Plains for the Listeners was a very good play on her part and a very awesome part in the book, especially with how calm El is about giving it up to her after spending so many Fused and resources trying to take it. And, EL HAS A SHARDBLADE? Anyway, I was pretty worried that Todium would have a complete victory over all three battlegrounds, but he only actually won Thaylenah. Speaking of the other battleground...
Adolin and the Azir plotline was epic, especially the end where he becomes Unoathed. It's sad that he's isolated from literally everyone now, and that he's going to have to wait a loooong time (if not forever) to get his leg back, but if Shallan is able to send a seon back to him, maybe they can communicate. I really loved Yanagawn's character growth, and learning more about how Towers works was pretty neat too.
After Mraize said his babsk wouldn't let him visit other planets, I was kind of hoping he could survive and become an actual Worldhopper, but his final confrontation and death by Shallan was very cool to watch. It pains me that if Shallan had run a little faster she wouldn't be stuck in the Cognitive Realm, but here she is, I guess. Pregnant, too. And after her conversation with Kelsier, I don't think she's going to try and visit other worlds with the risk of becoming too disconnected from her friends on Roshar due to the time dilation.
Oh, yeah, the time dilation. And all the other off-world shenanigans. I wasn't worried in the least when Wit got vaporized, and there was never a reason to worry anyway because he wakes up... in Elendel Basin!?!?!? And meets Ulaam and Miss Grimes?!?!? If anything, THAT was the biggest twist in the book. I know it might alienate readers who don't know Mistborn, but I would love to see more blatant crossovers like this. That's also why I'm excited for Isles of The Emberdark, simply because of the Rosharan-Scadrian interactions shown there.
Gavinor as Odium's Champion was expected, but still a little disappointing. At least he survives, although Dalinar is worse off. Technically it's not actually Dalinar who is in command of Retribution's armies (the actual Dalinar died), but the Blackthorn wreaking havoc across the Cosmere is a nightmare to consider.
Ba-Ado-Mishram was cool, Renarin and Rlain were cool, and yeah that's just the tip of the iceberg in thoughts I have on this book.
