Fenrir, in Norse mythology, is a monstrous wolf born of the god Loki and is prophesied to play a central role during Ragnarok. As he grows, Fenrir becomes increasingly feared by the gods, who bind him to prevent the foretold destruction. He symbolizes chaos and disruption, challenging the established order of the cosmic world. During Ragnarok, Fenrir breaks free and is destined to confront Odin, representing the inevitability of conflict and the cyclical nature of existence. His story underscores themes of fate, fear, and the struggle against chaos in Norse thought.
