Ragnarök is a Norse term that describes the end times when the universe is destroyed, along with all life in each of the nine worlds. The term Ragnarök is derived from an Old Norse word meaning "fate of the gods" or "twilight of the gods." The story of Ragnarök existed long before the spread of Christianity to Europe.

Valhalla , is the anglicised name for  Valhǫll ("hall of the slain").It is described as a majestic hall located in Asgard and presided over by the god Odin. Half of those who die in combat enter Valhalla, while the other half are chosen by the goddess Frejya to reside in Fólkvangr.The masses of those killed in combat (known as the Eingerjar ) , live in Valhalla until Ragnőrok when they will march out of its many doors to fight in aid of Odin against the jőtnar.
