S1, E6: Norse religion was integral to Scandinavian life. A creation myth tells of primeval frozen wastes and sacred trees. The pantheon contained gods of war (Odin), sky (Thor), and fertility (Frey and Freya). The afterlife in Valhalla and other great halls was a reward for great deeds. Worship of these gods, and veneration of their ancestors, united communities and separated them from Christendom.
