Britain. AD632.
Penda, a warrior of immense renown, has much to prove if he's to rule the Mercian kingdom and prevent the neighbouring king of Northumbria from claiming it.
Unexpectedly allying with the British kings, Penda races to battle the alliance of the Northumbrian king, unsure if his brother stands with him, or against him as they seek battle glory for themselves, and the right to rule gained through bloody conquest.
There will be a victor and a bloody loser and a king will rise from the ashes of the great and terrible battle of Hædfeld.
