Angor Fortress is the main site of operations of the Dark Iron dwarves in the Badlands. Here, they organize their exploration for exploiting Uldaman. An agent of Ragnaros, Ambassador Infernus, also resides in this keep.
In the RPG
Angor Fotress is controlled by Dark Iron dwarves. Ragnaros' fire elemental lieutenant, Ambassador Infernus, stays in Angor and keeps tabs on the Dark Irons who work for his master. The fortress' Dark Irons are concerned with the new dwarven dig site of Uldaman. They believe ancient Titan secrets hide within Uldaman — secrets that could help their fiery lord in his personal war. The Dark Irons are Ragnaros' thralls and they probably don't know of their Titan ancestry. If they do, their long association with dark powers has denied them Titan-born abilities. Brann Bronzebeard once fought one patrol of Dark Irons and immediately caused his flesh to harden: the Dark Irons seemed surprised at this ability.
