Dug out by Crystal Dwarves surviving in the plane, opposed by the horrors within the plane and their own evil infighting.
Level Design: Area near entrance compact and well structured rooms, as prepared by the dwarves. as you move south and to the left around a large bend and back north, the level falls apart as the dwarves foothold on that section is weak. The upper left will be open to the void of the plane, the right sealed.
