The duergar are the deep dwarves, solid, well muscled, and sinister beings who dwell in the bowels of the earth where even true dwarves fear to travel in small numbers. Pale skinned from aeons spent away from the light of the sun, duergar have rough craggy faces and jewel-hard eyes. Their skills at metallurgy and other crafts of metal and stone are exceptional, and their fierce strength has made it easy to conquer the tunnels where their cities are built. Other beings who dwell in these dark places must be ever-vigilant against the assault of their dark dwarf neighbors, for their might is incredible.
