In Norse mythology, Hel is a being who presides over a realm of the same name, where she receives a portion of the dead.
In the Poetic Edda, Prose Edda, and Heimskringla, Hel is referred to as a daughter of Loki, and to "go to Hel" is to die. In the Prose Edda book Gylfaginning, Hel is described as having been appointed by the god Odin as ruler of a realm of the same name, located in Niflheim. In the same source, her appearance is described as half blue and half flesh-coloured and further as having a gloomy, downcast appearance. The Prose Edda details that Hel rules over vast mansions with many servants in her underworld realm and plays a key role in the attempted resurrection of the god Baldr.
