Huginn and Muninn are a pair of giant ravens controlled telepathically by Odin. They were created for him as a gift by Hekate. They are immortal and capable of human speech. They become trapped in a shadowrealm, where they will presumably remain until the end of time.
- The ravens have no concept of boredom.
- Ordinary ravens, similar to parrots, are capable of emulating human speech to some degree (example).
