In Norse mythology, Ragnarök is a series of major events, including a great battle foretold to ultimately result in the death of a number of major figures (including the gods Odin, Thor, Freyr, Heimdall, and the jötunn Loki), the occurrence of various natural disasters, and the subsequent submersion of the world in water. Afterward, the world resurfaces anew and fertile, the surviving gods meet, and the world is repopulated by two human survivors. Ragnarök is an important event in the Norse canon, and has been the subject of scholarly discourse and theory.
