The center of the world.
In a towering structure of metallic grey and black.
In the town of Greyprohibition, some passing adventurers arrived here to explore.
"Why is there a city here?"
The adventurers asked.
The leader among them was a scarlet gold-grade adventurer, a figure standing at the pinnacle of the mortal world, one of the legends of today's Adventurer Guild.
And the indigenous inhabitants here informed them thusly: "Here is imprisoned a unique entity in the world, Celestial Will."
"They are the will of heaven and earth, the embodiment of all things."
"And our race has been tasked by the gods to guard the Celestial Will; this is our destiny."
The residents here are born with a mission, to guard this place for generations.
This caused some adventurers to marvel.
This world is truly magical and spectacular; even a remote town like this can be a place akin to the mythical stories where a Demon King is sealed.
Of course.
