Kingdoms rich in ancient grandeur, halls carved into the roots of mountains, the echoing of picks and hammers in deep mines and blazing forges, a commitment to clan and tradition, and a burning hatred of goblins and orcs—these common threads unite all dwarves.   Bold and hardy, dwarves are known as skilled warriors, miners, and workers of stone and metal. Though they stand well under 5 feet tall, dwarves are so broad and compact that they can weigh as much as a human standing nearly two feet taller. Their courage and endurance are also easily a match for any of the larger folk.   Dwarven skin ranges from deep brown to a paler hue tinged with red, but the most common shades are light brown or deep tan, like certain tones of earth. Their hair, worn long but in simple styles, is usually black, gray, or brown, though paler dwarves often have red hair. Male dwarves value their beards highly and groom them carefully.   Dwarves can live to be more than 400 years old, so the oldest living dwarves often remember a very different world. For example, some of the oldest dwarves living in Citadel Felbarr (in the world of the Forgotten Realms) can recall the day, more than three centuries ago, when orcs conquered the fortress and drove them into an exile that lasted over 250 years. This longevity grants them a perspective on the world that shorter-lived races such as humans and halflings lack.   Dwarves are solid and enduring like the mountains they love, weathering the passage of centuries with stoic endurance and little change. They respect the traditions of their clans, tracing their ancestry back to the founding of their most ancient strongholds in the youth of the world, and don’t abandon those traditions lightly. Part of those traditions is devotion to the gods of the dwarves, who uphold the dwarven ideals of industrious labor, skill in battle, and devotion to the forge.   Individual dwarves are determined and loyal, true to their word and decisive in action, sometimes to the point of stubbornness. Many dwarves have a strong sense of justice, and they are slow to forget wrongs they have suffered. A wrong done to one dwarf is a wrong done to the dwarf’s entire clan, so what begins as one dwarf’s hunt for vengeance can become a full-blown clan feud.   Dwarven kingdoms stretch deep beneath the mountains where the dwarves mine gems and precious metals and forge items of wonder. They love the beauty and artistry of precious metals and fine jewelry, and in some dwarves this love festers into avarice. Whatever wealth they can’t find in their mountains, they gain through trade. They dislike boats, so enterprising humans and halflings frequently handle trade in dwarven goods along water routes. Trustworthy members of other races are welcome in dwarf settlements, though some areas are off limits even to them.   The chief unit of dwarven society is the clan, and dwarves highly value social standing. Even dwarves who live far from their own kingdoms cherish their clan identities and affiliations, recognize related dwarves, and invoke their ancestors’ names in oaths and curses. To be clanless is the worst fate that can befall a dwarf.   Dwarves in other lands are typically artisans, especially weaponsmiths, armorers, and jewelers. Some become mercenaries or bodyguards, highly sought after for their courage and loyalty.   Dwarves who take up the adventuring life might be motivated by a desire for treasure—for its own sake, for a specific purpose, or even out of an altruistic desire to help others. Other dwarves are driven by the command or inspiration of a deity, a direct calling or simply a desire to bring glory to one of the dwarf gods. Clan and ancestry are also important motivators. A dwarf might seek to restore a clan’s lost honor, avenge an ancient wrong the clan suffered, or earn a new place within the clan after having been exiled. Or a dwarf might search for the axe wielded by a mighty ancestor, lost on the field of battle centuries ago.   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 Moradin 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 Moradin’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.
