A few weeks ago, I got curious about this term, as someone mentioned it somewhere. I google it, and find the trope entry here, and, as it turns out, my own story fits nicely with my own work in progress.
The basic story concept is this; what if there were 3 planets in 3 paralell universes that had humans look Negroid on one, Caucasoid on the other, and Mongoloid on the last? And what if each seperate universe had an overarching theological "truth" that was irrefutably true in their own universe, but totally false on the others? And what if there were dimensional gates that connected these three worlds?
My story fits, as the worlds have human dominated societies, human conflicts, Grey and Grey morality, a slighty cynical tone, a serious plot with a small bit of dark humor. The only exceptions are the inclusion of different magic systems, which is actually quite high for a low fantasy, and the science fiction elements mixed in there.
So, what's your story about, and how does it fit (or not fit) into low fantasy?
