Helvegen means The Way To Hel.
People who die in battle can hope to go either to Odin in Valhalla, or Freyja in Fólkvangr.
Most folk will end up with Hel in some part of Helheim (Home of Hel). Live an honorable life and keep your oaths or you may be sent to the nasty part of Hel called Náströnd (Corpse Shore).
