Duergar

The Duergar were the gray Dwarves that lived in the mountains of Thol Moldir. Because they were the children of Ogun(God of Earth), they were created a short time before their cousins, the Hill Dwarves, children of Rapel(God of Magnetism) and Epona(Goddess of Knowledge). They were responsible for some of the greatest feats of architecture and craftsmanship that the world has seen, for they were given magic as a consolation for their shorter life spans when compared to the elves.
