For 10 points, name this Norse goddess, the wife of Thor who was known for her golden hair.
In the 48th stanza of Harbard's song, this figure's reputation is assailed for supposedly having a lover at home. While not Freyr, this figure's only recorded sons are a forefather of Norse rulers who is only mentioned once in the Prose Edda and a god of hunting and archery who appropriately lives in a dwelling named after the yew tree, Ydalir. This figure was once married to the giant Orvandil, who is thought to have fathered her son Ullr. Sometimes associated with the Valkerie Hildr, this goddess has the ability to transform into a swan and is considered to be the rival of the giantess Jarnsaxa, with whom this goddess' husband fathered Magni. The ship Skidbladnir and the spear Gugnir were created along with an item that would later belong to this goddess; that item was created after this figure's husband threatened Loki to replace her hair, which Loki cut off.
