The Norse have folklore with mistletoe as well. According to mythology, Odin's son Baldr was prophesied to die. His mother, Frigg, went to all the plants and animals of the world securing an oath that they would not harm him. She overlooked and neglected to speak with the mistletoe, so Loki, a mischievous, shape-shifting god, made an arrow from mistletoe that was used to kill him.
