A duergar is relatively similar in appearance to a dwarf, except for the lack of hair on its scalp and its ashen-gray skin.
While many of the dwarves left their ancestral homelands in Nar-Voth in the Quest for Sky, there were many dwarves that refused to leave their long-held homes. These dwarves faced constant harassment and attacks from the other encroaching races of the Darklands. Faced with utter destruction, Droskar offered them a chance for survival. They accepted his deal and then became the Duergar.
