Dvergs are touched by the element of earth, and most have a metallic appearance in some way or other; skin the color of iron or copper, and eyes like molten metal. Their hair can be silvery, dark, or coppery, with dark being the most common. Dvergs are, like the earth which changed their nature, very stolid both emotionally and physically. This mostly means that they tend to be stronger, hardier and more stubborn than most; set in their ways, indifferent to others, unwilling to change their mind or their course unless forced, and more isolationist than any other of the elemental races. It's not clear where they originally came from, as there aren't large concentrations of them anywhere, except maybe the Valade Holds, where surturs, sylphs, dvergs and tritons have all congregated together to practice a strange form of elemental magic, but they are spread thinly across the continent, and are one of the least common races. Many of them will marry humans, and their children will usually be dvergs themselves; it is unusual to see large enough populations of dvergs that they marry each other and breed true. 

A dverg adds +1 to armor class and +1 to Constitution as a racial trait.
