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"). The brothers take the three women back to their hall with them—Egil takes Ölrún, Slagfiðr takes Hlaðguðr svanhvít and Völund takes Hervör alvitr. They live together for seven winters, until the women fly off to go to a battle and do not return. Egil goes off in snow-shoes to look for Ölrún, Slagfiðr goes searching for Hlaðguðr svanhvít and Völund sits in Úlfdalir.
