Notes

Ragnarok, in Norse mythology, marks the end of the old world, and the beginning of the new, current world. One of the many signs of ragnarock was a three-year winter which had no summer after each winter. This eventually led to a final battle on the Vigrid Plain, where the gods and the frost giants along with the undead fought the epic final battle.

Odin, who had previously attempted to prevent Ragnarok from occuring ( as he was most afraid of the world ending), led the gods. They were assisted by the heroic dead, those who had died in glorious battle who had been specifically chosen by Odin. They had been taken to live in Valhalla and await the final battle. The frost giants were led by the fire god Loki and assisted by the unworthy dead and other monsters who all came from the underworld also known as hell because the ruler was loki's daughter who was called hel.

Two humans, Lif and Lifthrasir, hid in a sacred tree called Yggdrasil during the battle and didn't return until after the battle. When they emerged, they repopulated the Earth. Other survivors of Ragnarok included some of the gods, particularly Odin's brother Honir, Odin's sons Vidar and Vali, Thor's sons Modi and Magni. Another of Odin's sons, Balder, was revived from the dead
