Hel
The daughter of Loki and a giantess named Angrboda, sister of Fenris and Jormungard (the Midgard serpent).
Troubled by prophecies that Loki's children would bring disaster, Odin ordered them imprisoned. Hel was thrown into Niflheim and ordered to look after those who die of sickness or old age. According to the Prose Edda, translated by Faulks, "Her hall is called Eliudnir, her dish Hunger, her knife Famine, the servant Ganglati, servingmaid Ganglot, her threshold where you enter Stumbling-block, her bed Sick-bed, her curtains Gleaming-bale. She is half black and half flesh-covered."
