Valkyries are like superheroes from Norse mythology. They are warrior goddesses who live in the heavens and fly around on winged horses. When brave warriors die in battle, the Valkyries choose which ones to take up to join Odin, the god of war, in his heavenly kingdom.
But the Valkyries don't just pick anyone. They look for the bravest, most honorable warriors who fought and died with courage and strength. These are the ones who get to go to Valhalla, a sort of Viking heaven, where they get to fight and feast all day.
So when Vikings went off to battle, they would pray to the Valkyries to choose them if they died. And if they were brave enough, these warrior goddesses might just come swooping in to take them up to the heavens.
In modern times, Valkyries are often depicted as fierce, powerful heroines in movies, TV shows, and video games. But their roots go back to ancient mythology and the idea that even in death, a warrior's bravery can earn them a place among the gods.
