Valhalla is a magnificent hall where slain warriors, known as Einherjar, are taken after death in Norse mythology. It is ruled by Odin, the chief god, and serves as a place of honor and feasting. Those who die bravely in battle are welcomed into Valhalla, where they prepare for Ragnarök, the end of days. Valhalla symbolizes the valor of warriors and the Norse cultural ideal of courage, heroism, and the belief in an afterlife that rewards bravery.
