Khagh Uluhm

 Red Jaw Mountain formerly known as Khagh Uluhm is a massive fortress-city of the Night Goblins of the Red Eye Tribe, which was conquered during the Goblin Wars. At the Dwarfs' height during the Golden Age, Khagh Uluhm boasted one of the deepest and richest mines in all of Dawi Und. As the ore and mineral deposits were finally dug out completely, the Dwarfs simply abandoned the tunnels, never expecting the consequences. During this time, the War of Elves was nearing its end and the Elves were a spent force, the Greenskins still kept to the Dark Lands, and the Vermin were still unknown. The occasional Troll wandering through the mines was seen as the only threat to the dominion of the Dwarfs.
