The most important gods of the Viking Age are Odin, representing war, magic and poetry, Thor, the god of growth and cosmic order, and the siblings Freyr and Freyja who represent fertility.

Besides the gods, there are giants, elves and dwarves. The gods live in a separate world (Asgard). They symbolize a higher cosmological order which they defend against giants and beasts that threaten to drag the world into chaos. At the end of time, they perish in the final battle Ragnarök. For some gods, like Tyr, the Old Germanic god of the sky, or mother deities, a much older age is assumed.
