Norse mythology refers to the Scandinavian mythological framework that was upheld during and around the time of the Viking Age (c. 790- c. 1100 CE). Before the Norse (a.k.a. the Vikings) converted to Christianity during the Middle Ages, they had their own vibrant native pagan religion that was as harshly beautiful as the Nordic landscape to which it was intimately connected.

An elf (plural: elves) is a type of humanlike supernatural being in Germanic mythology and folklore. In medieval Germanic-speaking cultures, elves seem generally to have been thought of as beings with magical powers and supernatural beauty, ambivalent towards everyday people and capable of either helping or hindering them.
