Halwa was located about 200 miles (320 km) east of Wasat within the desert of the Haunted Lands along Al-Malih River. Its lonely inland position next to the usually dry bed of Wadi Malih gave Halwa the title of City of Solitude.
Despite its location, Halwa was an active trading city, serving as a meeting point between city-dwellers and desert nomads. Livestock and durable goods were important commodities, as was care for caravans on their way to Hiyal and adventurers looking for riches in the desert. More sinister goods were sold in Halwa's underground slave market.
