In Norse tales, the goddess associated with the underworld is Hel, who rules over those who did not die a heroic death. She represents realms of the dead, depicted with half of her face as living and the other as decayed, symbolizing the balance between life and death. Hel’s realm, also named Hel, is where souls go to find peace, albeit not the honored afterlife of Valhalla. Her character emphasizes the regenerative aspects of death and the acceptance of mortality in Norse beliefs, highlighting a different dimension of existence beyond the physical world.
