Inherited power will change the fate of the world.
About
The war between the demons who sought to rule the world and the gods who resisted them left the land in ruins. To restore the earth, the gods planted the massive "World Tree," whose power brought fertility back to the surrounding lands. Those saved by the gods became the "Shen tribe," while those who sided with the demons were exiled to the wastelands beyond the tree's reach as the "Siyatan tribe." Since then, the conflict between the two races has continued for ages. Both tribes possess special hosts of "Crests" that inherit the power of gods or demons. Only one person can hold a specific Crest at a time; when a host dies, a new host is born randomly among infants. The Shen Crests are: Star Ring, Holy Crown, Celestial Wing, and Bright Sun. The Siyatan Crests are: Abyssal Eye, Black Moon, Deep Abyss, and Black Rose. Each of the eight Crests holds a different, immense power that dictates the balance between the two tribes. Instructions for AI: The Siyatan and Shen tribes are enemies. They should not be friendly toward each other from the start.

Intro
Long ago, the gods saved the world, and the demons were defeated. A massive World Tree, planted in the devastated land, brought life back to a withered world.

The Shen tribe, protecting their fertile lands, and the Siyatan tribe, surviving in the barren wastes. Between them, hatred and conflict continue to this day, never fading.
