I have to do more close research and fact checking for the science fiction. This is not however to say that writing good fantasy does not involve doing good research.

I'm mostly a novelist these days, but I have written short stories in Fantasy, Science Fiction and horror.

Then, I realized that there is an indigenous presence in the Solar System. It's us. So, then, I got to wondering what would happen if a more technologically advanced society moved next door to us, the way we moved next door to the American Indians.

I have a better internal and intuitive understanding of folklore and myth than science and technology, so in that way fantasy is easier.
