[Norse] The black elves of Norse mythology who grew from the maggots of Ymir's flesh. They live in the earth and in stones. Although they have the shape of men, they are often misshapen. Their home is Svartalfheim, which lies under the earth, and here they stay during daylight on pain of being turned to stone. The Svartalfar are often identified with the dvergar (dwarfs) and are hard to distinguish from the Döckálfar (the earth-dwelling ones).
