In Norse mythology, the afterlife is viewed through the lens of various realms, including Valhalla and Hel. Valhalla is depicted as a glorious hall for those who die in battle, where they feast and prepare for Ragnarök. In contrast, Hel is associated with those who die of illness or old age, embodying a more neutral, less heroic afterlife. These concepts reflect the Norse belief in valor and honor in life and death.
