Eight hundred years ago.
The Barren Mountain Tribe ruled over the barren mountain region, subjugating numerous tribes and wielding immense power.
However, strength did not guarantee safety.
The barren mountain area was filled with numerous mountains and forests, inhabited by fierce beasts and many supernatural creatures of immense power, beyond the capabilities of ordinary people to handle.
To protect their people, the Barren Mountain Tribe began campaigns against these supernatural creatures.
Faced with the overwhelming numbers of humans, many supernatural beings had to retreat, either into the Blue Sea or remote uninhabited areas.
This victorious defense enhanced the reputation of the Barren Mountain Tribe.
That asserted humans as the masters of the world.
