Duergar
The gray dwarves, or duergar, live deep in the Underdark. After delving deeper than any other dwarves, they were enslaved by mind flayers for eons. Although they eventually won their freedom, these grim, ashen-skinned dwarves now take slaves of their own and are as tyrannical as their former masters.
Physically similar to other dwarves in some ways, duergar are wiry and lean, with black eyes and bald heads, with the males growing long, unkempt, gray beards.
Duergar value toil above all else. Showing emotions other than grim determination or wrath is frowned on in their culture, but they can sometimes seem joyful when at work. They have the typical dwarven appreciation for order, tradition, and impeccable craftsmanship, but their goods are purely utilitarian, disdaining aesthetic or artistic value.
Few duergar become adventurers, fewer still on the surface world, because they are a hidebound and suspicious race. Those who leave their subterranean cities are usually exiles. Check with your Dungeon Master to see if you can play a gray dwarf character.
Duergar see themselves as the true manifestation of dwarven ideals, clever enough not to be taken in by the treacherous deceptions of Ctenmillar and his false promises. Their period of enslavement and the revolt against the mind flayers led by their god, Laduguer, purged the influence of the other dwarven gods from their souls and thus made them into the superior race.
Duergar have no appreciation for beauty, that ability having been erased from their minds by the mind flayers long ago and any thought of recapturing it obliterated by Ctenmillar’s betrayal. The duergar lead bleak, grim lives devoid of happiness or satisfaction, but they see that as their defining strength — the root of duergar pride, as it were — rather than a drawback to be corrected.
