Questioner
How do you build all your characters?
Brandon Sanderson
Characters are the hardest for me to explain. The answer I can give you is, I usually try writing and just experiment with the viewpoint and voice, and see if that works. And if it does, then I start working them into the book. But often, I'll do freewrites. I'm looking for conflict, looking for an interesting perspective of seeing the world. I'm just looking for something different about them.
Questioner
So, like, in Mistborn, do you create your characters individually, and then you add them to the story?
Brandon Sanderson
A lot of times. Like, Kelsier was created before I started writing Mistborn. Vin was also, but Vin changed a whole bunch, to the point that, really, I started writing the book, experimented with different voices, and found the one I wanted for her.
Questioner
How were you able to diversify the amount of characters you have? Like, Shallan, she had such a dark past. How do you get that so accurately?
Brandon Sanderson
I've had some help on Shallan. I've got some friends who have dealt with similar issues that I interview, I get notes from, and I have read the books and tell me where am I going wrong, where am I going right. That's really handy. Listening to people, interviewing people, using primary sources. Invaluable when doing characters. Even the newest book I'm working on, Skyward... Like, in that one, it's nothing about a deep, dark past, but the main character's a fighter pilot. And I got a ton of stuff wrong. But fortunately, I found some fighter pilots to read the book and tell me where I was going wrong. So it got right.
