You've said you lifted the Shattered Plains from Dragonsteel, what would Kaladin have been doing if not running bridges and what will happen to Dragonsteel without the Plains?
Both good questions. I've spoken before of the big changes that happened when I wrote The Way of Kings 2.0. One of them was bringing in the Shattered Plains. The problem was that there was a big hole in Kaladin's storyline, because in the original manuscript of The Way of Kings (major spoiler), he accepted the Shardblade. That was the prologue of the book; Kaladin—then known as Merin—saved Elhokar's life. They tried to take the Shardblade away from him, and Dalinar insisted that he be given it. So Merin was made a Shardbearer in the very first scenes of the book. And from that point, his character never worked. So in doing the second version of the book, I decided that no, we've got to build more into this, we've got to dig deeper, and he has to make the opposite decision, which is where the entire framework of him turning down the Shardblade and then being betrayed all came from. The problem was then what was he going to do? I knew I wanted him to have therefore ended up sold into slavery and have terrible things happen to him, but I couldn't figure out what Kaladin was going to do and was unable to write the book until I mashed in the Shattered Plains and said, "Ah, that was what he needed to be doing all along."
I really don't know what I'll do in Dragonsteel without that now. The problem is that it was the part of Dragonsteel that worked, but it was the part that was most at odds with the story in Dragonsteel. The story that I wanted to tell was the first half of the book, which is the more boring part. Hopefully as a better writer now I can make that part more interesting, but that was the core of what Dragonsteel was. The Shattered Plains was always just going to be a small diversion, but when I wrote it it was fascinating, and I ended up pouring tons of effort and time into it. In many ways it was a distraction, a deviation, a beautiful darling. So for a long time I've been thinking, "I can't kill my darling, because that's the most exciting part of the book." Yet it was at odds with what the story of the book was originally intended to be. I wasn't as good at controlling my stories back then, making them come out to have the tone I wanted. Anyway, we'll have to approach that when I actually write Dragonsteel.
