The cave entrance is a long tunnel, riddled with defensive works, that opens up into the hillside. A walled outpost has been built, which is used by the Dwarves as a trading hub where they sell and trade all their goods with merchants from the kingdom.
Further into the excavated cave, past the residential area, which can house close to 500 Dwarves, are additional tunnels and caverns that lead to the Dwarven forges and workplaces. The network of tunnels eventually leads to the Iron mines. The Dwarves found large deposits of iron ore during their excavations, which they now use to make their high quality steel and supply forges all over the kingdom.
