Baldr, who is portrayed as being a charming, beloved, innocent sufferer, had dreams that foretold his imminent death. His mother, Frigg, went around and obtained oaths from everything in the world that they would not harm her son. The only being she omitted was the mistletoe, as she thought it to be too small and harmless a thing to be of any real consequence in this matter. When the wily trickster Loki discovered this oversight, he fashioned a mistletoe spear.
While all the gods were amusing themselves by throwing every available projectile at Baldr and laughing as the things bounced off of their unharmed companion, Loki approached Hodr, portrayed as blind and rather gullible, with the mistletoe spear. He convinced Hodr to throw the spear at Baldr to contribute to the game and to honor the strength of his brother. With Loki guiding his hand, Hodr launched the spear at Baldr. The weapon pierced him, and, to the shock and horror of all present, he fell down dead on the spot.
In reaction to this, Odin and the giantess Rindr gave birth to Váli, who grew to adulthood within a day and slew the blind god. The death of Bladr, however, consequently set a chain of events as prophesied that with his death, Ragnarok will come to pass.
