What is the eschatology in Norse mythology?

In Norse mythology, eschatology is primarily encapsulated in the concept of Ragnarök, a series of events leading to the end of the world. This cataclysm involves a great battle between gods, giants, and various creatures, resulting in the death of many major deities, including Odin and Thor. Following this destruction, the world is foretold to be reborn, purified, and inhabited by surviving gods and humans. This cyclical view of creation and destruction reflects the Norse belief in the impermanence of life and the inevitability of change.
