Beowulf

…

… use it properly. In all three battles he was basically without a weapon other than his hands. When Beowulf slays the dragon a curse is laid upon his people for upsetting the flow of nature. This pretty much dooms them for a not at all prosperous future. They were doing fine until that thirteenth thane went and stole the flagon. This is precisely why man should leave nature to flow on its own course.
