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