To outsiders, the Netherworld has only seven layers, separated by seven stone gates sealed with divine curses.
In reality, however, there is an eighth layer to the Netherworld.
The reason why this place is unknown is that it houses the remains of the Divine Ancestor, Apsu. It is filled with highly corrosive black sludge, emanating the densest aura of death, making it the most dangerous place.
A soft sensation comes from beneath the feet, endless yellow-green plants sway in the dim light. This place is never illuminated by the sun, always resembling dusk or night, with no lamps around. White flowers sense the passing visitor, swaying in the breeze, appearing and disappearing like specters, emitting a faint glow.
The Golden Grain Flower, this is the unique plant, mentioned by the Shepherd God, capable of growing in the Netherworld and bringing vitality to it.
He spoke of it and succeeded in achieving it.
In fact, it turned out even more perfect than anticipated.
