Uldaman

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.
