This was the animal kingdom rightfully so, there was no other way to call this place. This was the only place Demi humans could proudly call home. Before the day of annihilation happened there were only humans that ruled the world, but after many years a lot of non-humans started appearing all of a sudden. Slowly but surely, humans realized that they were not going to be the most powerful species in the world anymore.
Seeing the growth of foreign species such as Demi-humans, most of the human civilization unanimously decided to welcome other races as allies. But still, there were some countries left that despised them to the core and wanted them dead. So, many groups with ill intentions formed, and many cults were born whose sole goal was to irradicate them from the earth. None of them survived facing the demi-humans, they were inherently more blessed than humans.
