Two years have passed since Alfred the Great successfully defeated Guthrum, King of the Vikings. The fair land of England is at peace. That is, until the harmony is threatened by Guthrum's angry, vengeful, illegitimate son, Rigr, who is hell-bent on usurping his father's throne. Rigr demands his Birthright - an acknowledgement that he is the sole heir to the Danelaw, but his father refuses his claim. Rigr assembles his army; a motley, but formidable, cohort of disenchanted warriors. Fearsome Guthrum, ruler of everything from Kent to Northumbria, is made aware of the threat and conjures his forces, meeting the rebellious host on the field at Thetford. Thousands upon thousands of bloodthirsty warriors confront each other on the sunlit, windless plains of East Anglia. The victors will rewrite the course of history, and the fate of England is in the hands of the gods of war.
