Rock

The Rock is an outcropping in Lower Istanople, and one of the only active mines in the Lower Kingdom. Free Dwarves mine gemstones there, including (on the third and lowest level) diamonds and ghost amethysts, the latter being a necessary component of arcane locks. Though immeasurably better off than their enslaved brethren in the north, dwarf miners at the Rock are still subjected to nasty conditions for little pay.
