A Valkyrie is a figure from Norse mythology, often depicted as a warrior maiden who serves the god Odin. Their primary role is to choose those who may die and those who may live in battles. The chosen warriors are taken to Valhalla, Odin's hall, where they prepare for the events of Ragnarok. Valkyries are typically portrayed as strong and noble, riding on horseback and wearing armor. They are associated with fate and destiny, guiding the souls of fallen heroes. In modern culture, Valkyries have appeared in various forms of media, including literature, films, and video games, often symbolizing strength and bravery.
