Uldaman is an ancient titan vault that has laid buried deep within the earth since ancient times. Dwarven excavations have penetrated this forgotten city, releasing the titans' first failed creations: the troggs. Legends say that the titans created troggs from stone. When they deemed the experiment a failure, the titans locked the troggs away and tried to create a new race - ultimately leading to the existence of dwarves as they're known today. The secrets of the dwarves' creation are recorded on the fabled Discs of Norgannon - massive titan artifacts that lie at the very bottom of the ancient city.

The Dark Iron dwarves have launched a series of incursions into Uldaman, hoping to claim the discs for their fiery master, Ragnaros. However, protecting the buried city are several guardians - giant constructs of living stone that crush any hapless intruders they find. The discs themselves are guarded by a massive, sentient Stonekeeper called Archaedas. Some rumors even suggest that the dwarves' stone-skinned ancestors, the earthen, still dwell deep within the city's hidden recesses.
