The Stone Chambers are the headquarters of the Hand of Stone. Hulidar Stonefist can be found here. It is located somewhere in Ironforge, no-one knows exactly where. Kagrim Thunderstone runs the actual area while Hulidar runs the guild itself. The building is rectangular with 4 floors.
Floor one is the defense base where Cyliann runs the guards of the base. Here is highly restricted and requires a seal of proof to enter. Many guards patrol this area and the tools are kept here.
Floor two is the Mechanics Quarters where Calank Fizzbolt and his Engineers design mining and scanning equipment. It is more metal than wood unlike the rest of the building. There are many machines here. All the Engineers are Gnomes, there are no Goblins, Calank only trusts Humans, Dwarves and Gnomes as Engineers.
Floor three is where Hulidar and Kagrim run the guild. Many high ranking officers report their finds here. The walls contain Mithril and Gold. A sample of an extremely rare, unknown metal is here. This floor has as many guards as Floor 1. Three guards are standing around the metal.
The large fourth floor holds the library, the largest section of the whole building. Aranor can be found here most of the time, reading, editing and maintaining the whole library. This is one of the most important facilities in the whole guild due to the fact that it stores all the knowledge gathered on metals.
