DC: Yes, I do. Part of creating a world that will serve as a setting for a book or series of books, is coming up with history for the world, a religion or set of religions, and a culture and sustainable society. It would be impossible to do these things without founding them on a series of myths and legends, just as the history, religious traditions, and cultures in our own world are based on mythologies and legends. So in creating these myths, I first have to be familiar with the ones in our own world. Prior to beginning the first book, I spent a good deal of time rereading the Greek myths, reading Celtic and Nordic mythology and even looking at some more esoteric sources, like Native American legends and Basque mythology. I learned a tremendous amount and had a good deal of fun in the process.
DL: What do you think is the important function of Fantasy?
I believe that fantasy -- and science fiction as well -- offers us an opportunity to look at important issues in our own world through a lens that grants us the freedom to look at things in a new light. For instance, as I mentioned before, my new series has a magic system that is racially based. Hence it deals with racial conflict. Well, writing about racial conflict (or cultural conflict or religious conflict, etc.) in mainstream literature is hard to do without offending one group or another. But by creating new worlds and thus changing the lexicon of the discussion, fantasy gives us the freedom to look at these issues without all the baggage we carry. There are no Eandi or Qirsi in our world -- the issues might be similar to racial issues in our world, but I'm not going to anger anyone as I point out injustices.
That, I believe, is one of the great values of all speculative fiction. Remember the so-called "Gay Episode" that was on "Star Trek: The Next Generation" several years ago. It dealt with homophobia in a direct, compelling way, but did so with a new vocabulary that perhaps allowed people to see the issue in ways they never had before.
