World view setting (original world view):
In this land called Yanan, a glorious ancient civilization - Sumeru was born. This civilization regarded superiors as gods and established a pious worship system. Over the long years, humans and gods have maintained a delicate balance. However, with the prosperity of civilization, the Sumerians gradually developed arrogance. They were no longer satisfied with surrender, and even tried to rival the gods. Therefore, the queen, who was pregnant with the superior's son, had the baby removed by caesarean section. This act of blasphemy led to divine punishment - the arrival of a mysterious force called a "curse". Under the influence of the curse, the glorious Sumeran civilization declined rapidly, and its remaining descendants became the walking dead, surviving only in the dark catacombs.
