Ragnarok is a term from Norse mythology that refers to the end of the world. According to legend, Ragnarok is a final battle between the gods and giants, where most of the major gods and goddesses, including Odin, Thor, and Loki, are killed. The event marks the destruction and rebirth of the world, where a new world rises from the ashes of the old one.
The legend of Ragnarok is told in several different sources, including the Poetic Edda, the Prose Edda, and the Heimskringla. In these sources, the events leading up to Ragnarok are described, including the rise of evil and the breaking of alliances among the gods. The actual battle of Ragnarok involves many terrible events, such as the death of the god Baldr, the unleashing of the wolf Fenrir, and the swallowing of the sun and moon by the wolf Skoll and the giantess Hati.
After the battle, the world is reborn, with a new generation of gods and a new era of peace and prosperity. The surviving gods gather at the newly created Idavoll plain, where they build a new, golden hall called Gimli. This new world is free from evil, and the gods are able to live in peace and harmony.
Ragnarok has been a popular theme in modern media, including movies, video games, and books, and is often used to symbolize the end of an era or a major change in the world.
