Man this was a fun journey, but it's kind of sad that I caught up so quickly having started stormlight only a few months ago. That said I love it, it's my favorite sanderson series and I look forward to book 5 immensely. I read the audiobooks, listening to them at work. I think Michael Kramer is absolutely killing it, I understand some people love him and others don't like him but I really like him, although it always feels weird to hear him voicing characters Kate Reading normally voices, such as pattern. Kate's pattern voice is just perfect, sells the comedy of the character a lot.
Here's some wild shot predictions:
Prediction 1: Shallan
I don't know how, I don't know what caused it, but somehow Shallan has been invested with breaths of life from warbreaker. There was a scene, I think it was in either RoW or Oathbringer, where Veil notes that Shallan sees colors with more detail than her, and the way it was phrased was exactly like the warbreaker breaths. There's also the way that Shallan's drawing powers only work for her and not her other personalities, as well as the similar ways that her drawing power works to things like perfect pitch or sight from warbreaker, makes me so confident this is the case. It also explains why a cryptic like pattern was willing to bond with her, even though she'd already killed her previous cryptic. It makes the fact that Wit reacted so strongly as soon as he saw her as a child make more sense as well.
It makes me wonder if maybe Shallan's whole family isn't actually from Roshar, and maybe they were brought there from the Warbreaker world after some big conflict there. My gut feeling is that they may in fact be a royal family from there, just because Shallan's father reminds me of Siri's father for some reason. This would also explain why BS has said he can't write the Warbreaker sequel until after stormlight book 5.
I think Shallan's Mother was almost certainly a member of the ghostbloods, and tried to kill Shallan, after which Shallan responded by summoning Testament to defend herself. There's still a lot about Shallan that doesn't add up and after the Testament reveal I want to re-read way of kings because there's a lot about what happens to her in that book that still doesn't make sense to me. In particular the line "what are you" that I believe one of the cryptic spren said to her back then feels off now.
Prediction 2: Kaladin
I think we'll definitely go to the horneater peaks in book 5 for sure. I don't know how book 5 is going to end, or how different "part 2" of stormlight archive is going to be from "part 1," but BS has been promising the horneater peaks since book 1, it's clear that whatever's going on with Rock is a BIG deal in the narrative and I am certain Kal hasn't seen the last of Rock yet, despite what was said in RoW.
Kal has come a long way in swearing the 4th ideal, and while I once thought he would swear the 5th for sure in book 5 after finishing RoW I no longer think this. The 5th ideal definitely needs to span at least 2 books of buildup because otherwise it wouldn't feel like as big and important a deal as the 4th.
As for bridge 4, I don't know where they stand to go as characters. It feels sad how lately a lot of them seemed to be killed off in order to help kal come to terms with the 4th ideal, maybe now we won't have to worry about so many of them dying off since he's come to terms with it, as unrealistic as that sounds. I really just want a scene of the remaining members of bridge 4 getting together and hanging out, having fun. They deserve it.
Prediction 3: Dalinar
I have a feeling, a sinking feeling, that Dalinar is going to lose the contest of champions. It just doesn't feel right, it wouldn't work for a big climax for this massive story with so many key characters to be a battle between only two, especially when one of the champions was only introduced at the end of book 4. I think he'll fully realize his powers as a bondsmith but lose the contest somehow.
Anyways, those are my predictions! I don't know if the community as a whole has already predicted similar things, or if people feel I am wayyyy off base with these, just wanted to get my thoughts out since the story is fresh out of my mind. really glad I can finally discuss this series now that I've hit the current end.
