How do the characters come to be? I think one of the most interesting, my favorite character is probably Kaladin. How does Kaladin...
Brandon Sanderson
So, Kaladin had an interesting story behind him. I had originally wrote Way of Kings in 2002, and one of the things that didn't work with that draft was that Kaladin's character didn't work. He was called Merin back then. And it's just, personality didn't work. I'd written him too much like a classic apprentice kid on the battlefield who distinguishes himself, it was just too standard of a kind of fantasy storyline. And so I'm like, "Who is this person?" I needed more depth for him, so I added the whole "His father's a surgeon, he's trained as a surgeon" thing. That was one of the first big pillar I added to add more depth to Kaladin, was "All right, he's a surgeon, but he's been forced to go to war." The kind of field medic who also learns he's really good at killing people. That was, like, the first big thing that I got for Kaladin.
The other thing was the big tragedy that happened in his past, followed by the big tragedy involving the Shardblade led me down that path. And the last thing I added was the depression. This was, like, seven years of evolving this character before he actually came together. Characters are hard for me to put a finger on, because I usually write them by instinct. I'll write a chapter from their viewpoint, see how they see the world, step back. And I'll usually throw that chapter away and try it several times until I get the right... soul, cast in the role, if that makes sense. I can talk a lot more about other things, but character is trial and error until someone feels right.
The more distinctive you can make a character's viewpoint, the stronger, I feel, it will come across. When I feel like it's really working for me is when I can write a few paragraphs and say, "No other character that I've ever written could have written those paragraphs, just in how they describe the world."
