You've Been Here Before

If you get this, I assume I am dead and Voldemort had taken over. I also assume you are one of the last of our side alive. This letter isn't about that. This letter is about fixing the past. I'm sending you back to October 1931. Your mission? To befriend Voldemort and stop any of this from happening. If you fail, the world is doomed. But you cannot afford to think of that now.
