We have added the Wow in-game lore: Lorekeeper of Norgannon given when you defeat the Norgannon watcher in the instance of Uldaman. At the end, you get access to the Uldaman Discs which tell a lot of lore about the origin of the Dwarves and Troggs, and the bases of the Titans. Besides Uldaman there are two other Titan bases in Azeroth: Ulduar in Northrend and Uldum in Tanaris, Kalimdor. You can find out more about Uldum and Ulduar here.
