The Valkyrie origin story has roots in Norse mythology. Valkyries were female figures who served Odin. They were often depicted as choosing who would die in battle and who would be taken to Valhalla. They were seen as fierce and powerful, flying over battlefields on their horses.
In most cases, the story of Valkyrie is not real. It typically exists in the realm of fantasy and cultural imagination, with elements drawn from ancient myths and storytelling traditions. These stories are often used to convey symbolic or moral messages rather than representing actual events.
