In Norse myths, the end of days for gods and men is foretold by the prophetess Völva during Ragnarök. This apocalyptic event entails a great battle where gods like Odin and Thor face off against the forces of chaos. It signifies not only destruction but also transformation, leading to a rebirth of the world. The concept emphasizes themes of inevitability and the cyclical nature of existence, illustrating how endings often pave the way for new beginnings.
