Assignment: Turn this Annal into a history. Write a no more than three page history of this world, based on this one source.

One rule: you can make things up, but you can’t get more information. Don’t go to Wikipedia and look up Duke Gottfried or Blessed Bede, the presbyter. How can you make sense of this simply from this extremely limited source?

You can write it as fiction if you like. But at the end you have to write a conclusion saying how you did it. What did it take to make this into a history?
