Höðr, or Hod, was the god of winter and the blind son of Odin and Frigg who was tricked by Loki into killing his twin brother Baldr with a dart made of mistletoe, as it was the only thing which could kill him. This was because Baldr's mother, Frigg, made everything in existence swear never to harm Baldr, except for the mistletoe, which she found too unimportant to ask. He was later killed by Vali, his half-brother, born specifically for this task. Though Höðr died, he and Baldr were in the world created after Ragnarok.
