You have managed to invent time travel!
And your first trip takes you back to Anglo Saxon times, more specifically 1066, when the Normans have invaded. Whose side are you on, The Anglo-Saxon King Harold or William of Normandy? What do each of them stand for and why would you choose them? You can present this how you would like, could be a diary entry, a newspaper report, or just a piece of writing. Don't forget your punctuation (Capital Letters Nightingales!) and to check your spelling using a dictionary (such as https://dictionary.cambridge.org/).
