Alluvia

A city state that is built in the recesses of an ancient sand river delta. The different stone types in the ground here have been differently affected by the harsh erosion of sand, and a winding network of narrow passages has been formed with colourful walls of layered sandstone.. Due to the heavy nature of the sand, the sand now still only flows through the deepest and biggest tranches, leaving the smaller and higher ravines open. This proved an effective hiding place from the punishing sandstorms, and had a built-in drainage system for the sands. Now, it is a sprawling city, with meandering streets filled with merchants, craftsmen and even the occasional poorer noble.

As the city expanded and prime location property increased in value, slums started to appear around the trenches in various sized holes and craters in the surrounding landscape. These would house the poorest of the Alluvians, dubbed the "Mold" by upper-class society, who thought of themselves as being the only ones fit to own walled property.
