In Norse mythology, the term "valkyrie" refers to warrior maidens serving the god Odin. Their primary role is to select those who may die and those who may live in battles. Valkyries guide the souls of fallen warriors to Valhalla, Odin’s hall, where the warriors prepare for Ragnarok. They symbolize strength, honor, and the revered status of warriors in Norse culture, reflecting the values of bravery and sacrifice.
