In ancient times, a divine spirit nourished by all creation was born into the mortal realm. This spirit split into two halves—one good and one evil. Should the evil half devour the remaining part, it would become the supreme ruler of heaven and earth, plunging the three realms into hellish torment. The only solution lies in its other half, which exists in mutual generation and restriction with it.

However, this also requires a person of unique bloodline. The tavern that Vyara Moonfell runs in the city of Shadowspire exists solely to await this destined one.
