"I've got a solid grounding in history, sociology, anthropology, philosophy, etc etc. That means I actually have a good idea about how societies change and evolve. I know how a lot of them have actually functioned through the years. I can put together a culture that's cool and different, while still being logically consistent, so that it feels real. So many fantasy worlds are either implausible, cookie-cutter, or both. Mine aren't."
