In a world just like Earth, there are animals, plants, and humans. Even with humanity's advanced technology, humans are not the undisputed rulers of the world, because there are creatures even stronger than humans: the Qi.
The Qi are like humans, yet different. They feed on people! Since the Qi live for a very long time and are all emotionless creatures, they can go their whole lives without taking a mate. So there are very few of them, but they remain a great threat to humanity.
