In Norse mythology, Éljúðnir is the hall where Hel receives the dead.
The name appears in the Prose Edda’s description of Hel’s realm. Hel is both the ruler of that realm and, in many modern discussions, the name used for the destination itself. Éljúðnir is specifically presented as her hall, making it a more precise answer than simply saying “Hel.”
This distinction matters because Norse afterlife traditions describe several destinations rather than one universal heaven or hell. Warriors selected in battle may be associated with Valhalla or Fólkvangr, while many others go to Hel. The surviving sources do not provide a single systematic theology for every death, and later popular culture often simplifies these different places into a neat good-versus-bad division that the medieval texts do not consistently establish.
