Laughing Hairfoot is an ancient mine of the Armânuk hills. The mine is sited fifteen miles due north of Maurkac. Over the past one thousand years, it grew to be a vast labyrinth of tunnels and chambers. The lower reaches of the mine lead into Faeglor. At the point where the tunnels meet the caverns of Sigan-Kûn, is an Underdark citadel turned town. This once served as a defensive area between the mines and the Underdark. In the centuries after the Khazarkar Empire claimed Gholompotl, this area became more secure and the citadel became more like a town than a fortress.
The Laughing Hairfoot mine has passed through three great families. It was first mined by the a halfling house named Haog. As a result of this one mine, the Haogs became a noble family of Maurkac. They held the mine for 16 years. They lost the mine as a result of a very large gambling debt to the Hannanâthas. House Hannanâtha came to prominence during the Nermanis Syndicate. They got their wealth from ore coming out of the Laughing Hairfoot and other mines.
The Hannanâthas lost the deed to the mine when they experienced a period of bad luck at the gambling tables of Nirzanâth. The Urkuzîr took control of the mine and worked it into the 1700s.
When the mine had finally been expended, after nearly a millennia of digging, it spread across hundreds of miles of tunnels. In 1719, the Urkuzîrs sold the deed to a wealthy Svirfneblin family by the name of Shinszelmoggit. The Shinszelmoggits took claim of the tunnels and an Underdark citadel. This citadel once served as the living quarters for the former Underdark workforce of the Urkuzîr. The place was turned into a trading post and town. It serves as a trade center between the surface and the Underdark and between traders of the Underdark. The citadel was renamed Fermin and has since expanded into a sizeable town of 5,000 souls.
In the deepest reaches of Laughing Hairfoot are portals to Granitoid. These portals lead to a continuation of the mining passages on this world, mines called the Laughing Pipes.
