Ravens are held sacred in Norse mythology and are heavily associated with Odin. Huginn (idea) and Muninn (memory) perch upon Odin’s shoulders and whisper the secrets of the world to him. Each morning they take to the skies of Midgard, returning each evening to report their gathered knowledge to the god of wisdom, divination, and magic.
Ravens are prominent features within Celtic mythology. The Morrígan, Phantom Queen and Shape-Shifter, is the Irish goddess of war, death and destiny. She circled battlefields as a conspiracy of Ravens to consume the souls of fallen warriors and carry their souls to the realm of the dead.
