Seven thousand years before the current events within Equestria, a great betrayal occurred.

Humanity was on the verge of devastation, as was their foe, the Vampires. With the assistance of a rogue Vampire House's Patriarch, an Omega Level Vampire by the name of "Maximillian Adelhelm Fremont", Humanity managed to genetically engineer three equine-like races to combat the Vampire threat without risk of their own forces. Through the Patriarch's blood, they also engineered two surviving Test Subjects that had all three's traits and could control them. However, after discovering that his legitimate children and heirs were to be used as nothing but breeders... The Omega Level Vampire made a decision that forever damned his entire House. He freed every Test Subject, and his two daughters, from Humanity's hold.

Now, seven thousand years after the "Forgotten Ones" destroyed themselves, the Vampire Curse has risen again within Pony Kind. A beloved DJ holds the dreaded secret of being one of these terrible nightstalkers, but sworn to hunt down the one that had cursed her to such a fate. But, after having a bad run in with over zealous Vampire Hunters, she finds herself within Castle Fremont and at the mercy of the ancient House's Vampire King.

Will Maximillian Adelhelm Fremont assist in her endeavors? Does he have some other ulterior motive for helping her? What shall the Royal Sisters think of the newest addition to their Royal House? And if Maximillian did not bring back the Vampire's Curse... Who did?
