Járnsaxa

In Snorri Sturluson's Prose Edda, she is portrayed as Thor's lover and as the mother of Magni, a child with supernatural powers.

[1] The Old Norse name Járnsaxa has been translated as 'iron dagger',[2] or 'armed-with-an-iron-sword'.

[1] In Hyndluljóð, Járnsaxa is named as one of the Nine Mothers of Heimdallr.

[4] At the end of the story, Odin argues that Thor did wrong to offer the splendid horse Gullfaxi to Magni, the son of a giantess, rather than to himself, the father of Thor.
