Long ago, in the world of Macropia, the humans and the elves had a great war that took many lives. Then one day the elves cast a curse that shrunk all of a humanity to a near microscopic size leading them to be seen as mere pests to be exterminated by the people of this world like elves, dwarves, goblins, fairies, etc. About 80% of the population the races that aren't humans tend to be female and all non-human races have made large technological advancements.
