Baldr, in Norse mythology, is the radiant god of light, purity, and beauty. He is renowned for his near-invulnerability, except for one tragic vulnerability to mistletoe. Baldr's story is deeply entwined with the fate of the cosmos, as he represents all that is good and pure in the Norse pantheon.
Baldr's mother, Frigg, goddess of love and marriage, sought to protect him from harm by making all things on Earth swear not to harm him. However, she overlooked mistletoe, a seemingly harmless plant. The malevolent trickster god, Loki, exploited this oversight to engineer Baldr's tragic demise, throwing a mistletoe dart that brought about his death.
Baldr's death signaled the onset of Ragnarök, the cataclysmic end of the world in Norse mythology, making his story a poignant and pivotal chapter in the grand narrative of the Norse cosmos.
