At what point did you go, "Elantris was good, Mistborn was good, now let's do 40 more books"?
So, a brief, brief history (writer's side, not the in-world side) of the Cosmere is this. So, Elantris was written without the cosmere in mind. This was-- Elantris was the first, kind of, book in my--
So, the way my history works, I was told early on that your first five books are generally terrible. And this was actually really relieving to me, because I'm like "Oh, I don't have to be good until book six." So I wrote five books as, just, lots of experimenting. Lots of different types of stories. And I didn't really even try, I sent one or two of them out, but I didn't really aggressively try to publish them. They were White Sand--not White Sand that you can get from my newsletter signup, an earlier version--which is my first book. And then Star's End, which was a little science fiction book, and then a sequel to White Sand, and something called Knight Life, which was a comedy. Yes. But bits of that got repurposed into Alcatraz. And then The Sixth Incarnation of Pandora, which was a weird cyberpunk, far-future thing. And I got done with all of those, and I'm like, "All right. I kind of know what I want to do. I thought it was epic fantasy. I now know it's epic fantasy." And then I wrote Elantris. My next books were Elantris, a rewrite of White Sand, and Dragonsteel. And this was kind of me exploring "What do I want to do? How do I want to-- What is my-- What do I want to add to this genre?"
But the idea of the interconnected universe grew out of doing these things, writing these books. I started planning The Way of Kings then, I started planning the book that became Warbreaker then. It was called Mythwalker at the time. And I wrote a book called The Final Empire and a another one called Mistborn, which are neither of the ones that you guys actually have read. What eventually happened, is when I sold Elantris, this whole thing of the cosmere had really come together, this is what I wanted to do, I was really excited by it.
And so, the first book that I wrote knowing about the cosmere was Mistborn. And Elantris got retrofitted into this as I was writing the Mistborn trilogy. And it was while I was working on the Mistborn trilogy that I made the nine book arc that is kind of the core, though-line of the Cosmere, the past/present/future Mistborn. I called my editor in... 2005 with a really big, exciting, sort of huge outline for 40 books (it was 32 back then), I'm like, "It's gonna be this, it's gonna be this, it connects here, and all this stuff--" That's when it all kind of happened, and I built that all out. It was the process of working on the Mistborn original trilogy and building out the nine book arc for those that really solidified a lot of these ideas. By then, I had written Dragonsteel, so I knew--- Dragonsteel was book number seven, so I knew about Adonalsium and all of this stuff, but it was really kind of in Mistborn where I decided how I was gonna incorporate all of that. And even then, even in Mistborn, there are still things that I was still putting together.
So, yeah. There's a brief history of it. By the time I had those three books done, 'cause I wrote them in a row, I was pretty solid on how all of this was gonna come together.
