The Dwarves 
The Shaper's Sons, Born of Stone

The Sons of Stone are unlike any other people in our World, for they alone neither age nor breed. Legends say that Dwarves are not born, but rather that their entire race was molded by the hand of Thurin the Strong, the truest of the All-Father's great Companions. Crafted from the Stone of the Earth, the Dwarves were charged by their maker to tend to the Great Fires that boil in the belly of the World. For most of recorded history the Dwarves worked in secret, delving vast halls, building wondrous citadels, and mastering the arts of mining and forgecraft. In the days since the Turning, the mysterious Dwarves have finally returned to the surface World, and the peoples of the World have come in contact with their mysterious ways for the first time in Ages. There are no females among their kind, and they produce no offspring. Dwarves do not seem to die of old age, and it may be that all of them have existed since the day of Creation. When a dwarf dies, the entire race mourns… for that is one less dwarf that our World shall ever know.
