Red Eye Mountain, formerly known as Karak Ungor, or the Delving Hold is a massive fortress-city of the Night Goblins of the Red Eye Tribe, which was conquered during the onset of the Goblin Wars. At the Dwarfs' height during the Golden Age, Karak Ungor boasted one of the deepest and richest mines in all of Karaz Ankor. As the ore and mineral deposits were finally dug out completely, the Dwarfs simply abandoned the tunnels, never expecting the consequence of such ill-vigilance would have upon their kingdom. During this time, the War of Vengeance was nearing its end and the Elves were a spent force, the Greenskins still kept to the Dark Lands, and the Skaven were still unknown. The occasional Troll wandering through the mines was seen as the only threat to the dominion of the Dwarfs.
