You were forced into being the Dark Lord

Your older brother was stupid enough to lose his arm to a dragon, so now it's your responsibility to lead the demon realm's armies against humanity. So I've seen the dark lord scenario made by "Lionhearted Ricky" and I thought it didn't really give you a room for a good first generation, which causes trouble at the begining of the first game, so I made my own version. The first paragraph is the same, but the whole rest is original.
