You spent your whole life in service to the gods of Asgard. You died an honorable death. You earned your place in the halls of Valhalla. But when you knocked on its gates to receive your final reward, none answered. Odin has turned his back on your people. He underestimates the Viking spirit. He underestimates you.
Force their hand as you lead your people past the dangers waiting on Valhalla Hills and fight to prove your honor, your strength, your worthiness. Look after your Vikings, gathering food, chopping wood, and mastering the complex economics of wilderness survival. Reach the portal at the top of each mountain, and shout your battle cry loud enough for the gods to hear.
If they will not give your people the reward you all deserve, then by your axe, you will take it from them.
