Undermoor was established around −3900 DR and dwarven miners first dug the tunnels and chambers that would eventually become known as Undermoor. The dwarves found unusual veins of magical ore, but in their digging, they encountered the slumbering primordial. After that disastrous encounter, the dwarves sealed the tunnels and focused finding a new home. It has only recently been opened to visitors, withe the construction of newer external buildings, which prevent guests from entering the forge.

The city was built on a massive scale, with many doorways large enough that even dragons could pass through them. Doorways were constructed from iron, mithral and stone. These doors were designed to be opened only by a citizen of Undermoor. They were both magically sealed and tremendously heavy. The city was adorned with icons to the Morndinsamman, the dwarven pantheon, and other dwarven heroes.

Millennia later, the primordial was rediscovered by the arcanist Maerin of Illusk. He convinced the dwarves to build a city around the mines of Undermoor in order to harness the power of the primordial to create exceptional pieces of metalwork.

By, 1484 DR, the drow had secured the area around the forge and some of the lower mining tunnels, where they forced slaves to work. That year, House Xorlarrin received official approval to leave Plague Citadel for the new settlement, which was named Q’Xorlarrin. Not long before the Drow Matron was set to arrive, drow troops captured Artemis Entreri and his companions and tortured them or set them to work. The reborn Companions of the Hall, who entered Undermoor to free Thibbledorf Pwent from his vampiric curse, learned about Entreri’s captivity and set out to rescue him. In the ensuing fight, the drow were forced to retreat temporarily and many of the settlement’s rooms were destroyed. However, The dwarves moved quickly to rebuild the city.

In the upper levels and around the Iron Tabernacle and Vault of Kings, Undermoor is brightly lit. Driftglobes, phosphorescent fungi, and huge braziers and troughs of burning coals fill most hallways and chambers. Lights in many parts of the city are dimmed somewhat during the nighttime hours, so that its residents can mark the passage of time on the surface world. In the lower reaches, around the Great Forge, light isn’t as ubiquitous. Farther down, and in parts of the city yet to be reclaimed from the ruins of the past, there is no light other than whatever visitors bring with them.
