I've mentioned my side-project in another thread I think where essentially it's set in modern-day in a world where rather than hide from the eyes of mankind, fantasy and supernatural creatures and mankind have build their own society. There's a task force in the government/police that deal with crimes related to supernatural origins of magic. I've been creating this world's lore and I'm coming to the modern age. My original idea was to have mankind's pursuit of new technologies like gunpowder instead of magic drive the other species (Elves, Dwarves, Ravens ect) away from mankind and eventually go into hiding only to be rediscovered after world war two. My concern was that it seems kinda dumb especially with three of the species being more advanced and the alliance they shared in past wars. That and humanity wouldn't so easily forget about something that was such a big part of it's history, especially if it's the discovery of stuff like gunpowder that creates a divide. The other problem is that I'm establishing the Dwarves as the technologically advanced species. If so, they'd probably discover gunpowder before the humans. In short, the original idea has a lot of problems. My issue is that I don't have much of an alternative. All the inventions of the modern world exist (cars, guns, phones, WIFI ect) but in order for those things to exist a lot of events in human history have to happen (i.e no satellite communications if there isn't a space race/cold war). I need help with an alternative history that would still allow a lot of the events in human history to happen.
