In Norse mythology, Valkyries are warrior maidens serving Odin, tasked with selecting those who may die or live in battles. They escort the souls of slain warriors to Valhalla, the hall of the slain, where these heroes prepare for the final conflict at Ragnarok. Valkyries symbolize strength, bravery, and the warrior spirit, embodying ideals of honor and valor. Their involvement in choosing the fates of men highlights themes of destiny and mortality in Norse culture. They also represent the connection between life, death, and the afterlife, reinforcing the cyclical nature of existence.
