When Kowal was built, the rulers hired dworvs to help design the town. These dworvs were recently expelled from the Kingdom of Greyhelm for their “heretical beliefs” (they would later be known as the Free Dworvs as they had escaped the strict religious culture of Greyhelm).
When they set up their construction camp for Kowal, the speicfically built it in a chaotic fashion as a complete rejection of the Greyhelm organizational building style. As the tents became shacks, and shacks became buildings, Dworvtown stayed one of the most randomly designed wards of Kowal.
These days, Dworvtown is compromised of many squat square buildings, mostly one or two stories. The people here are of varied heritage, but the dworvs still make up the highest population in this area.
