Setup: Divide players into two equal teams. One the "English" the other "The Normans". The English appoint a Crown.
Play
The Normans invade the English with the intent to kill the English Crown. If the Crown is killed the Norman responsible becomes the new English Crown. If the Crown is not killed, the Normans pick from the dead of the English for reinforcements.
The game is finished when there are no Normans left to invade or the English are eliminated. This can take a very long time and may in fact never happen. Play ends when players request a new game or the marshals get bored.
