The Chronicles of Etinerra
Dwarfs were once the vassals of the Dark Ones in ages past. Freed by Man and Elves, Dwarfs retreated out of sight of the other races, content to live their lives in peace and away from civilization. It is said that Dwarfs became one with the lands and weather that they lived in, becoming almost barbaric and nomadic in their Northern retreats, and known for periodic outbreaks of attacks and looting upon the civilized worlds. Those same stories spoke of mobile tent cities with wondrous things beyond mortal comprehension and of wealth in trading with these Dwarfs.
Yet since the Doom of Man, little has been seen or heard from the Dwarfs. It is wondered aloud if they have disappeared in the cataclysm that has shaken the lands.
