 A prose introduction in the poem "Völundarkviða" relates that the brothers Slagfiðr, Egil and Völund dwelt in a house sited in a location called Úlfdalir ("wolf dales").There, early one morning, the brothers find three women spinning linen on the shore of the lake Úlfsjár ("wolf lake"), and "near them were their swan's garments; they were valkyries".Two daughters of King Hlödvér are named Hlaðguðr svanhvít ("swan-white") and Hervör alvitr (possibly meaning "all-wise" or "strange creature"); the third, daughter of Kjárr of Valland, is named Ölrún (possibly meaning "beer rune").
