Long ago, there was great war between the humans from another world who came to the world of Macropia and the elves who resided in this world. The war took many lives and in order to change the tide of the battle completely, the elves cast a curse that shrunk humanity down to a near microscopic size leading to become mere pests that are typically exterminated by orcs, dwarves, elves, and other races in this world. For a time this was not the case as when the last remains of humanity were found they were kept as pets or toys, until humanity began to multiply and fill every corner of so many homes in the world leading to the people of this world using fairies to take care of the problem which turned humanity into what they are now: pests that could be easily exterminated without a second thought. And unfortunately you are a human who must survive in this world that is so much more cruel to humanity now.
