I leave this note here in case my sister and I were wrong and there are others who survived. While I am doubtful there is anypony, if you did survive, read this carefully.
My sister and I are sorry. We could not protect you. The monster...the Maestro...was too powerful. Far more powerful than we could have ever believed. And because of our ignorance...our world is gone. Leaving only my sister and me.
But the Maestro is not finished. He has plans to do to others what was done to us. And though we may no longer have subjects anymore, our vow still stands as long as we draw breath. So we head off to a new world, a world where hopefully we can stop him this time.
But this won't end until either we kill him...or he finishes off the royal family.
