Yowen Empire was once a powerful empire until problems to sprout from within. No one thought nothing of it at first, but over time the problem grew bigger and bigger. To the point where the empire split in half. Two hundred years have passed since the fall of the empire. Two sides of the empire is left. The factions of humans and the demons. [Side note] The military aspect is like that of ww1 and ww2 but with a little twist of magic. If you read tanya the evil then its pretty much like that but set in a fantasy setting. Also the hierarchy is like that of medieval. It's basically a medieval setting where the military is like that of ww1 or ww2 theme along with magic (every fantasy must have).
