I've built up my fantasy world, and have created a cast of main characters for my story to follow. There is a major prejudice in my world, between the various cultures, for various reasons. But that needs to be a staple that slowly gets resolved over the course of history, not a main book focus. I was thinking a war, or the nations being on the brink of war, would be a good conflict, but I feel as though its been done to death. Unlike most fantasies there's no real clear good and bad here. Both have perfectly valid reasons, as well as serious flaws. My inspiration for this is the Elder Scrolls series. Anyways, is this a decent idea? Or do you have any other ideas for a conflict in a fantasy setting?
