The map is based on the information in the book and critrolewiki. There isnt that much explicit information about its exact buildup, so i made some guesses with that.

One of the most prominent things is the "rainbow vineyard" and Kamordah has a famous wine making industry, so i made huge vineyards with colorful plants to reflect the effect of the strange soil in the area. Kamordah is close to the mountains, so i made it close to the foothills of Mt. Mentiri. Kamordah is surrounded by the Bromkin Hills, so i also showed them on the map around the town.

Because of this soil making normal water resources not possible i put a lot of water towers all over the city, fetching the rain for later use. Another feature described are the central mudfields harboring greenhouses. I put a small lake with some of the undrinkable water in the middle to reflect that and a lot of strange looking houses doing research on that and the soil.

The southern part of Kamordah houses more shackles and smaller houses for the lower working class, while the north is for the rich merchants and other people. Kamordah is also know to not have a dedicated church or temple. It seems that the Dwendalian Empire razed those (mostly now forbidden gods) temples from Kamordah. A huge temple area with a lot of ruins is in the south.
