Uldaman is an ancient Titan vault that has laid buried within the earth since the world's creation. Dwarven excavations of the city have recently released the Titans' first failed creations: the troggs. Legends say that when the Titans deemed the trogg experiment a failure they tried again, resulting in the creation of the dwarven race. These secrets are recorded on the fabled Discs of Norgannon - massive artifacts that lie at the bottom of the ancient city, protected by giant constructs of living stone.
