Dear Princess Celestia,
I guess I've been addressing you as Princess again because I don't deserve what you've given me. It won't matter soon, anyway. The bleeding makes it difficult to concentrate. It's funny, I fought so hard to stop her from doing this to me or anypony else. But a life for a life is fair, right?
By this point, you probably already tried teleporting into my castle and bounced off the wards. I'm sorry, Princess, I just can't deal with this anymore, and soon enough you'll understand too. It's a fair price and one I can't make anypony else pay.
I guess you won't understand immediately, but it's best for Equestria if ponies didn't have a Princess who might kill them. I've reviewed seventeen different points of failure in how I became a murderer. This is the only way.
I'm so sorry.
Your faithful st
