No one knows when it began—
But the world was split in two.
Those in the Upper City live in the sunlight, on vast lands, warm and free.
Those in the Lower City survive in a cramped, suffocating underground where no light ever reaches—even the air is lethal.
In a dark alley, a crazed old man laughs madly as he gulps down cheap liquor and howls at the sky:
“Oh, noble masters of the Upper City! In your eyes, do we people of the Lower City…
count as human at all?”
