Selenian dwarves' aetherial power allows them to survive the thin atmosphere of the Grey Moon, shape stone, and see in the dark. They also gain other powers from their work with lunar stone and soil, often gaining powers such as having reflective eyes that reveal supernatural energies, bringing light from stone, and imbuing stone with lightness.

All dwarves are known for their steady feet, their inborn toughness, and their shrewdness.

Selenian dwarves live in cities that are built half in the side of lunar mountains and half in the caves within them. They spend the bright hours inside and the dark ones outside, in order to survive the changes in atmosphere. Outside the cities, they have small communities run by councils of three. Inside the cities, larger councils (always of multiples of three) run things, and all councils answer to a thane. The thane changes every three hundred years, selected by the councils.

Selenian dwarven families are made up of three generations. After three generations, a new generation starts a new family with other families. These families build into large communities that chose members of the councils from their elders.

The craftsfolk in their societies range from masons to miners to smiths, using lunar materials to gain earthpower and lunar aether, and pot-makers, who gather the moonbeams with lunar aether. They have schools and guilds for every craft and more.
