Thousand-Year War
The Thousand-Year War was a great war between the jotnarr and the gods. The world of Midgard collapsed under the destructive force of the fire giants from the world of Muspelheim, under the command of the jotunn Satan Morroc. They were confronted by the king of the gods, Odin, and were eventually defeated. Satan Morroc was cast back to Muspelheim, only to emerge 1,080 years later.
The war was supposed to culminate into the cataclysm known as Ragnarok, ending the age of the gods.
