The dagger of stamford

Those timelords wanted me to see the battle of hastings, so i went. Everytime i travel in time, it feels like a part of me is always left behind. The butterfly effect always takes its prize no matter how small and significant.. I saw Harold, one of the most feared warriors ever lived just to become an outcast of a witch spell..
If people only knew it was my dagger that ended a war that never should have taken place.. I saw into Harolds soul and took a glimpse of the future if he would have won, so i did my bid.. And ended it with a sharp blade to his heart..
He looked into my eyes and said;" I never thought it would be you"
