the City of Glass is a very ancient underground city made of golden tinted glass lined tunnels and chambers. Its smooth rounded walls were fused from the sand using magical techniques and contain embedded light sources which glow when living beings are in proximity. Furniture is limited to pillows (now turned to dust), standing wood & stone workbenches, and built-in wooden & glass shelving, typically ornately carved.

the city of glass connects to the westwood scarp caverns and the Prince's Crossing underground. An entry is also accessible via the cemetery by way of a greider tunnel.
