Hel was the goddess of the underworlds, Helheim and Niflheim, in Norse mythology. Odin threw Hel there and gave her authority over those who do not die gloriously in battle but of sickness or of old age. She has a body which is half black, half flesh-covered, and appears downcast yet fierce, according to Snorri Sturluson in Gylfaginning. Her dwelling place is the hall Eliudnir. Her servants were Ganglati and Ganglot.
