In Norse tales, Hel is the goddess of the underworld, and she is the daughter of Loki, the trickster god. Hel oversees those who did not die a hero's death and governs the realm of the dead. Her relationship with Loki emphasizes the theme of duality within Norse mythology, as Loki embodies chaos while Hel represents the inevitability of death. Together, they demonstrate how familial ties can reflect the broader struggles between fate, chaos, and the afterlife.
