Valhalla means the "hall of the slain" in ancient Norse language. It is a majestic hall in Norse mythology located in Asgard and ruled by the god Odin. Valhalla is where the bravest warriors who died in battle, known as the slain or einherjar, are taken by Valkyries to live gloriously. They spend their afterlife preparing for the final battle of Ragnarok, feasting and fighting daily, but healed every evening to fight again. It symbolizes honor, eternal glory, and the highest reward for warrior valor in Viking culture.
