Zeirulious Klien Makavar, a mysterious pony who appeared out of the blue. To start the RavenWood Academy, in what would eventually be known as Equestria. In this time, so far past and forgotten. Even the Changelings wandered the halls of RavenWood, with out fear.
But something is happening within the walls. Ponies are vanishing into thin air, to resurface days later mauled to death by an unknown source. The only question is, what is doing it?

(Changeling Tag due to there being Changelings later on in the story.)
