Okay, as I've said many times, I'm not a fantasy writer. I'm a crime/historical/sci-fi writer, but all my work includes aspects of spec fic. I'm currently writing a sequel to a sci-fi novel and what I most want to convey is a very different atmosphere to what we earthlings are used to... So what are we used to? And how would an alien world feel? It's very simple to describe an alien world where green little bastards zap ray guns and get about in anti-grav sleds, but what about the way it feels? This applies as much to fantasy worlds as sci-fi worlds. What do you do to make it feel real? Because if it doesn't feel real, it won't work.
