Solar calendar year 561.
According to historical records, in this year, red rain fell from the sky, demons appeared on the ground, natural disasters occurred frequently, and civil strife continued. The invasion of the orc empire and the threat of the dragon have made mankind besieged from both sides and plunged into a desperate situation on the verge of destruction.
In order to survive, humans and spiritual beasts, the two weakest races, signed a contract. This day was called the "Day of Recovery" by later generations - the beginning of the recovery of human hope and the beginning of human counterattack.
They are called "Spirit Envoys".
