How do you come up with and create the maps for your novels? Is it a process of thought while creating the story itself or does it come later once you've written the story as a means to depict the places you've written about? Also do you scetch [sic] them yourself before having them drawn or is the process usually entirely done by a separate artist?

I usually sketch myself out something vague to use as reference, then make it more and more detailed as I work through the book. At that point, I approach and artist and have them help me come up with a good visual style for the book and the map. If it's an artist I know well, I can sometimes let them do more of the work—the Mistborn maps, for instance, were developed by Isaac with very little input from me beyond the text and some basic instructions.
