Angrboða

Angrboða is a jötunn in Norse mythology. She is the mate of Loki and the mother of monsters. She is only mentioned once in the Poetic Edda as the mother of Fenrir by Loki. The Prose Edda (Gylfaginning) describes her as "a giantess in Jötunheimar" and as the mother of three monsters: the wolf Fenrir, the Midgard serpent Jörmungandr, and the ruler of the dead Hel.
