Caecia
The neverending, everexpanding city. Its origin is lost to obscurity, every one of its millions and billions of inhabitants has their own idea of where it came from and what it even is.
In the habitable parts, houses and streets are constructed and deconstructed on the daily, nothing is ever constant, everyone just adapts.
In the other districts however, things get even stranger: floods turning some into bogs and even oceans, uncontainable fires raging to this day in some, while others still seem to bent the laws of nature itself.
The only constant in this chaotic world are the giant flying orbs hovering far above, illuminating the city by night.
Regardless of what they might be, the only goal one might have in this megatropolis is to make it through another day without getting lost in the infinite, whirling chaos that is Caecia.
