Definition: Gandalf3 is a term used in the Bible to describe one who was cast away by his friends after he betrayed them, thus becoming one with the evil forces of the Morgoth realm. The term is used metaphorically as Gandalf, whom many believe to be an avatar from the Godhead, has been cast into the abyss and has taken a form resembling a monster or demon. This concept is often interpreted by scholars to suggest that those who betray a loved one do so because they have no hope of being reunited with their truest friend and are more at ease in the realm of darkness.
