In Scandinavian mythology, Huld is only referenced by völva or seiðkona, that is a woman who practiced the seiðr. She is mentioned in the Ynglinga saga, Sturlunga saga and a late medieval Icelandic tale. In the latter source, she is Odin's mistress and the mother of the demi-goddesses Þorgerðr and Irpa. As her name suggests, Huld may be in origin the same being as the Huldra and the German Holda.
In the Ynglinga saga it is related that she was first hired to kill the Swedish king Vanlade, by his wife Drífa. She "hag-rode" him to death.
Vanlandi hét son Svegðis, er ríki tók eptir hann ok réð fyrir Uppsala auð; hann var hermaðr mikill, ok hann fór víða um lönd. Hann þá vetrvist á Finnlandi með Snjá hinum gamla, ok fékk þar dóttur hans Drífu. En at vári fór hann á brott, en Drífa var eptir, ok hét hann at koma aptr á þriggja vetra fresti; en hann kom eigi á 10 vetrum. Þá sendi Drífa eptir Huld seiðkonu, en sendi Vísbur, son þeirra Vanlanda, til Svíþjóðar. Drífa keypti at Huld seiðkonu, at hon skyldi síða Vanlanda til Finnlands, eða deyða hann at öðrum kosti. En er seiðr var framiðr, þá var Vanlandi at Uppsölum; þá gerði hann fúsan at fara til Finnlands, en vinir hans ok ráðamenn bönnuðu honum, ok sögðu at vera mundi fjölkyngi Finna í farfýsi hans. Þá gerðist honum svefnhöfugt, ok lagðist hann till svefns. En er hann hafði lítt sofnat, kallaði hann ok sagði, at mara trað hann. Menn hans fóru til ok vildu hjálpa honum; en er þeir tóku uppi til höfuðsins, þá trað hon fótleggina, svá at nær brotnuðu; þá tóku þeir til fótanna, þá kafði hon höfuðit, svá at þar dó hann. Svíar tóku lík hans, ok var hann brendr við á þá er Skúta heitir. Þar váru settir bautasteinar hans.
Vanlande, Swegde's son, succeeded his father, and ruled over the Upsal domain. He was a great warrior, and went far around in different lands. Once he took up his winter abode in Lapland with Snae the Old, and got his daughter Driva in marriage; but in spring he set out leaving Driva behind, and although he had promised to return within three years he did not come back for ten. Then Driva sent a message to the witch Huld; and sent Visbur, her son by Vanlande, to Sweden. Driva bribed the witch-wife Huld, either that she should bewitch Vanlande to return to Finland, or kill him. When this witch-work was going on Vanlande was at Upsal, and a great desire came over him to go to Finland; but his friends and counsellors advised him against it, and said the witchcraft of the Finn people showed itself in this desire of his to go there. He then became very drowsy, and laid himself down to sleep; but when he had slept but a little while he cried out, saying that the Mara was treading upon him. His men hastened to him to help him; but when they took hold of his head she trod on his legs, and when they laid hold of his legs she pressed upon his head; and it was his death. The Swedes took his body and burnt it at a river called Skytaa, where a standing stone was raised over him.
