The world is divided into four parts: the Wilds Continent to the south, humanity to the east, the Phantom Beasts to the west, and, towering in the north, a tall tower that gives off a faint pressure. Every living thing that passes nearby takes a detour.
The Wilds Continent itself is divided into two regions: the Primeval Forest and the Wilds Plains.
Countless creatures live and multiply across that continent. Over the ages, they gradually formed countless races, among which the four greatest are the Peng Clan, the Ape Clan, the Otherworldly Clan, and the Mechanical Clan. The Peng and Ape Clans rule the Primeval Forest together, while the Otherworldly and Mechanical Clans jointly rule the plains.
The Wilds Continent and the other three regions all connect to a single continent: the Primeval Continent. We call the passage from each region to the Primeval Continent the Sacred Path!
Note: In everyday life, members of every race take human form because it's more convenient. They only reveal their true forms at certain times.
