–from Norse Mythology for Smart People by Daniel McCoy
Norse mythology includes several places where the dead go. Odin’s hall, Valhalla (Hall of the Fallen), and Hel’s underground domain, Hel (the Hidden), are the most well known, but perhaps that is more due to the influence of Christianity which introduced heaven and hell as the reward and punishment meted out according to how humans lived during their lifetimes.
There are also Freya’s hall, Folkvang (Field of the People), and the underwater abode of the giantess, Ran, where those who drowned were sometimes gathered.
More is known about Valhalla than the other places. Valhalla is where Odin chooses the best of the fallen warriors, brought to him by the valkyries, to live with him until Ragnarok. Once there, they become einherjar, those who fight alone. While there, the einherjar do what warriors do best–they fight. Each evening their wounds and injuries are healed, and they feast and drink. And so life-after-death goes on.
