Duergar

Long ago, as the humanoid races were beginning to chafe under the yoke of Chromatic Dragons' slavery, one group of Dwarves overthrew their dragon overlords and escaped by fleeing deeper underground. For millennia, these dwarves have kept mostly to themselves, living deep underground, seldom venturing above ground.
They soon encountered another danger when some of them breached a hidden laboratory belonging to the goddess Rivy/Liadi. Those who couldn't escape became Derro, and the rest fled, abandoning their brethren and collapsing the tunnels behind them.

Basic Information

Anatomy

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.

Civilization and Culture

Beauty Ideals

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.
