In Scandinavian myths, the event that marks the end of the world is known as Ragnarök. This cataclysmic series of events involves a great battle between gods, giants, and various beasts, leading to the deaths of key figures such as Odin, Thor, and Freyja. Ragnarök brings about the destruction of the world, but it also signifies rebirth, as it is believed new lands will emerge and surviving gods will repopulate the earth. This cycle of destruction and renewal reflects deep themes in mythology regarding fate, mortality, and the resilience of life.
