The Map Chamber is located inside Uldaman, past the Hall of the Keepers. Like many other parts of the dungeon, it is crawling with troggs. The hall leads into a series of rough tunnels to the northwest, that eventually end up in Echomok Cavern, Dig Three, Temple Hall, or the Stone Vault, depending on which route is picked.
The main feature of the Map Chamber is a large model map of Uldaman in all its former glory embedded in the floor. By combining the and (Gni'kiv Tsol spells 'Lost Viking' backwards, a reference to an early Blizzard game), and creating the , one can insert the latter into the model map and open the door to a hidden chamber featuring Ironaya.
The layout of Uldaman on the floor, and the use of a staff, created from a medallion and a "shaft, to create a beam to show the opening to a hidden chamber are most likely a reference to Indiana Jones and the Raiders of the Lost Ark; more specifically, to the map chamber that showed the way to the Well of Souls, where the Ark of the Covenant was held in the film. Like Tanis in the film, which was buried under the sand in a sandstorm that lasted a whole year, Uldaman was buried beneath the earth (presumably due to the Great Sundering) and is being excavated for its powerful contents.
