Much of the English language fantasy genre is very loosely based on a northern European medieval European vibe. This isn't surprising; the English language genre is largely derived from the mythology, folklore and medieval romances that predated fantasy per se. I've obviously gone in some different directions--on purpose, in an attempt to create a different feel. While the Crown of Aragon and a kind of Latin Mediterranean vibe is a huge part of the DARK•HERITAGE setting, at least culturally, and I've got a nation that is clearly modelled somewhat transparently on some aspects of the Moorish caliphate combined with Ottoman Barbary pirates. I also see certain aspects of my setting as specifically trying to model other historical scenarios, perhaps transparently, and perhaps not. I've got an Old West of sorts. I've got a Caribbean from the Golden Age of Piracy. I've got Cajuns. I've got South Pacific natives here and there.
I've also got stuff borrowed from fiction. I've got plenty of Lovecraftiana. I've got my take on Bael Turath, from the Dungeons & Dragons 4e points of light setting.
Not that the northern European stuff isn't part of my heritage too--I just think that aspect of my heritage is already adequately covered in the modern fantasty genre, and it's past time to explore more. I'm also part Mediterranean, via a Portuguese great-great grandfather, and of course, after many generations, I'm really much more American than I am European anyway. America is my home. I love it. I want that to be reflected in my fantasy.
