In Norse mythology, Valkyries are depicted as warrior maidens who serve Odin. They possess the unique ability to choose those who may die and those who may live in battles. Valkyries are known for their beauty, strength, and courage, often riding on horses and donning armor. Once they select fallen warriors, they escort them to Valhalla, where the chosen fight and dine until the Ragnarok confrontation. Their dual role as both guides and choosers emphasizes the Norse view of fate and honor in battle.
