In Viking lore, the deity that oversees the dead in Valhalla is Odin. Valhalla is depicted as a grand hall where warriors who died valorously in battle are welcomed, and Odin decides the fate of the souls. He is often associated with wisdom and poetry, and his role as the ruler of the slain emphasizes his connection to heroic ideals. Those chosen by the Valkyries to enter Valhalla are said to prepare for the final battle, or Ragnarök, showcasing the importance of bravery and valor in Viking culture.
