We had liberated Luna from the darkness known as Nightmare Moon, just as Celestia had asked of us, even if we all did it for the good of Equestria.

Just as we set Discord in stone, although we later liberated him and helped him back to a life worth living with friends. Celestia had entrusted the second part of this in Flutter Shy's capable hands, apparently she knew.

That is in the past, things has happened since.

Now I am a Queen in my own right. I have Chysalis by my side. She proved to be both nice and helpful, when you got to know her. We never did know her back then.
