The lands of Equestria are harsh and often violent as the dangers surrounding the young country play their games. Celestia and Luna do their best, but sometimes its not enough to deal with every little detail that pops up from time to time.

That's when she comes into play.

A strange creature with familiar powers was brought forth to this world, and by luck was bound to Celestia's will. As the summoner of this strange, but powerful creature, Celestia wasted no time using her to tip the scale into Equestria's favor.

The only problem is Luna doesn't know about this dangerous pact, and the creature hates everything the Sun touches. Sooner or later, the boundaries that held her in check will shift, and than the Nightmare will be free.
