A normal day in Ponyville is about to be disturbed when a strange creature comes from out of nowhere. At first he seems to be friendly and can be trusted, but something is bothering him. The death of someone close or somepony.
Celestia sense a new threat from an ancient enemy, something Luna isn't aware off.
Is the arrival of this unknow creature a coincidence with this new threat or not? But one thing is certain, he's the only one who can save Equestria... or destroys it.
