What is "laufey"

Laufey or Nál is a figure from Norse mythology, the mother of Loki and consort of Fárbauti. Eddic poetry refers to Loki by the matronym Loki Laufeyjarson ( Old Norse 'Loki Laufey's son') rather than with a patronymic.

Laufey is a fictional supervillain appearing in American comic books published by Marvel Comics. The character is depicted usually as an enemy of the Asgardian king Odin, father of Thor. He is the King of the Frost Giants, the biological father of Thor's adopted brother and archenemy, Loki. Created by writer Stan Lee and artist Jack Kirby, he first appeared in Journey into Mystery #112 (Jan. 1965), and was based on the frost giantess of the same name who, in Norse mythology was actually the mother of Loki.
