For 10 points, identify this deity whose golden hair was remade by dwarves who also forged Mjolnir and Gungnir, the wife of Thor.
In some sources, this goddess is used to fill in for Nerthus and is a patroness of harvests, and she is also equivalent to the Lapp goddess Ravdna. The mother of an archer-god, she is able to take the form of a swan. Once married to Orvandil, she is portrayed in one legend as a "man hating woman" by a god who tells her how she cuckolded her husband after being presented a cup of mead and suggested the seeking of a woman without fault. A wager which resulted from an assault upon this deity led to Eitri's awl being used in an attempt to sew shut the lips of another figure. Through her first husband, she bore the god of winter and skiing, and became the stepmother of Magni and Modi, before Loki cut off her hair.
