There are only two worlds - your world, which is the real world, and other worlds, the fantasy. Worlds like this are worlds of the human imagination: their reality, or lack of reality, is not important. What is important is that they are there. these worlds provide an alternative. Provide an escape. Provide a threat. Provide a dream, and power; provide refuge, and pain. They give your world meaning. They do not exist; and thus they are all that matters.
Neil Gaiman"Only write what you know" is very good advice. I do my best to stick to it. I wrote about gods and dreams and America because I knew about them. And I wrote about what it's like to wander into Faerie because I knew about that. I wrote about living underneath London because I knew about that too. And I put people into the stories because I knew them: the ones with pumpkins for heads, and the serial killers with eyes for teeth, and the little chocolate people filled with raspberry cream and the rest of them.
Neil GaimanWhereas there are lots of good novels out there; there are a few good movies out there. People have been writing great poems for years, but there aren't a lot of good comics. I like trying to write them.
