Hel is a figure from Norse mythology, known as the goddess of the underworld. She is the daughter of the trickster god Loki and the giantess Angerboda. Hel rules over the realm also called Hel, where those who did not die a heroic death go after they pass away. In appearance, Hel is often described as having a half-living and half-dead visage, symbolizing her dominion over life and death. Her domain is a place of rest for the souls of the deceased, contrasting with the fiery realm of Niflheim and the glorious hall of Valhalla.
