There are a number of things that I'm trying to get into the books. There's a meta-fictional aspect, if I may use that pretentious word, to writing anything. You're writing in the shadow of all the people that have gone before and, in a way, you're having a dialogue with them. As someone who's read J.R. Tolkien and Robert E. Howard and all the great fantasists before, this is almost my answer to them.
