From the introduction: The Molten City was long ago built by the warrior king Kharg the Fiery, carved into the side of the great mountains they harness the power of the fiery below to power the city. The city covers many levels, walkways connecting each other them above the molten magma bubbling below. The streets are much like those you’d see in any city apart from the walkways that allow access from district to district. Taverns and stores of all kinds are very common, dealing easily with the influx of visitors that come here for it’s master crafted weapons and armor. Even purchasing exotic magical goods or rare ores is possible in the Molten City. It also houses many temples for the worship of the gods and accommodation in surplus.
