Geri and Freki
In Norse mythology, Geri and Freki (Old Norse: "the ravenous" and "greedy one") are two wolves who are said to accompany the god Odin. The two are most often seen at Odin's side when he is in Valhalla, feasting with the warriors who dwell in its numerous halls. They are said to devour those who would present false information to or otherwise lie to Odin.
