Vampires, Werewolves, the Old God. Unnoticed by the general public, these three forces prepared for a war of historical proportions. Since the unforeseen resurfacing of a long-forgotten heirloom has renewed their lust for power, their schemes have taken on an unscrupulous nature, eventually making the monarchs of Equestria aware of their ploys.

The need for protection gave birth to a small task force consisting of Sweetie Belle, her older sister, and Twilight Sparkle, accompanied by Spike the Dragon. Together they are under royal order to ensure the safety of the civilians while upholding an absolute degree of discreetness.

Time will tell how these four secret heroes will brave the challenges ahead.
