Raven is considered one of the oldest and wisest of animals. Raven is a contrary spirit. On the negative side, Raven represents the profane, the devil, evil spirits, the trickster and thief, war and destruction, death and doom, the void.
Yet in many cultures Raven also represents deep magic, the mystery of the unknown, death and transformation, creation, healing, wisdom, protection, and prophecy.
...and its tar.
