As the title asks. Anything related to the question is what I meant, but I meant a bit more concrete, like how George used A Song of Ice and Fire = War of Roses. Of course it can be just minor inspiration to specific people or whatever. I have one character that is not so much in the story, but is leading an enormous war on the other side of the world. He is a conqueror and believed unstoppable. My historic relation would be Genghis Khan. (Of course since this character won't be a PoV, nor seen by another PoV (as of now) there is not that much development on his front, except that he is taking over the entire eastern continent.) I also have a fantasy like version of the black plague, still pretty early thinking because it won't happen till at least the second or third novel. And I have been meddling on nordic story, for example like with Loki , Hel and Fenrir. Of course non-godlike and realistic-like. What about you?
