In Glæsisvellir could be found a location called Odainsaker, or Údáinsakr(meaning: Deathless Acre). Everyone who went there became healthy and young, and so no one ever died in Odainsaker. The Eireks saga víðförla is about a man who searched for and found Údáinsakr.
In the Hervarar saga, it is the kingdom of Gudmund and his son Höfund. Gudmund was a friendly giant who was popular in later sagas.
