This is a place of questionable labor and of unknown treachery.
At this location most if not all do not return. There are heavily armed guards along with other unmentionable things that go bump in the utter darkness. To be sent here is to receive a almost certain death sentence.
This place is also where the power crystals are mined. You will see them in staffs, hats or other places. The crystals are primarily used by wizards and sorceresses to enhance their power.
