Ragnarök

Ragnarök is an ancient belief from the Norse culture. It means the end of the world. It is said that all the gods and goddesses will fight each other in a big battle and the world will be destroyed by fire. After that, the world will be reborn with some of the gods and goddesses surviving. Ragnarok is like a big reset button for the world.
