Ysgard
This plane is Valhalla, the Viking plane of the afterlife. People who come here drink all night and fight all day. At the end of the day, the plane's magic resurrects those slain in the day's fighting, and they all go in to get drunk and tell stories. Those slain outside the plane will NOT come back if their corpses are taken there.
The people who populate this plane are valiant warriors who liked battle so much they never wanted to stop doing it, but didn't want to feel bad about killing people and also didn't want to live forever.
