Odin’s two ravens, Hugin and Munin, a pair of ravens that fly all over the world, Midgard, and bring information to the god Odin. Huginn and Muninn are attested in the Poetic Edda. In the Edda, a disguised Odin expresses that he fears that they may not return from their daily flights. The Prose Edda explains that Odin is referred to as "raven-god" due to his association with Huginn and Muninn. In the Prose Edda and the Third Grammatical Treatise, the two ravens are described as perching on Odin's shoulders. Heimskringla details that Odin gave Huginn and Muninn the ability to speak.
