Princess Celestia is an immortal princess, so it makes sense she has had many students. But when a number of mistakes leads three of them to abandon their studies, Celestia vows to not make the same mistakes with the remaining student. But what lead them to leave anyway?

So my first story. This is a prequel of sorts to the main universe. The universe that is yet to be published. This universe shall be named... The SpoJuverse! All will become clear. Soon.

Soon

EDIT: Oh My GOD. I made it on to the third page of popular stories. That was unexpected. Most unexpected.
