The sky here is forever unseen, only an endless expanse of smog and light pollution.
The air always hangs heavy with the pungent smell of engine oil, or the strange odor wafting from decomposing "biological waste."
Whir, whir, whir...
One day.
A disc-shaped spacecraft, approximately ten kilometers in diameter, tore through the smog and arrived here. Before the disc-shaped craft hovered over the waste processing station in Zone 11, it seemed like an alien object, forcefully pushing aside the densely particulate smog overhead. White, green, and red beams of light refracted through the smog, forming a spectacular "rainbow cloud," as if conveying some kind of signal.
In traditional terms, the image of an "unidentified flying object" in fantasy books is not much different from that gigantic object in the sky.
Buzz.
