This is a peculiar world. The only history anyone can find here covers the past ten thousand years; what happened before that is unknown. Since time immemorial, beasts have ruled this vast world, establishing a hierarchy of the survival of the fittest through generation after generation. But one day, this order was disrupted. A group of humans of unknown origin arrived from beyond the heavens and found the once-weak human tribes. From then on, humanity began its rise to power.
