Huginn

Huginn (Old Norse: Huginn, "thought") is one of Odin's two ravens. Each day Huginn and his companion Muninn fly out over Midgard and the other worlds, returning in the evening to perch on Odin's shoulders and report what they have seen. Huginn represents thought and reason. In Grímnismál, Odin says he fears that Huginn may not return — but fears even more for Muninn.
