Grey Dwarf

After rising up against their mind flayer enslavers, the gray dwarves, or duergar, emerged as a new subrace of dwarf with limited mental powers. Duergar on the whole are evil, but some turn their backs on their fellows and seek a different sort of life. Male and female duergar are bald, and women do not grow beards. They are much thinner than other dwarves, with severe facial expressions, gray hair, and gray skin.
