In a time unknown, before Equestria, the princesses, and the Elements of Harmony, before the War of Three Powers, there existed a fair kingdom, ruled over by the wise King Guardia.

Within his court was one equine that had abilities beyond what others had. He had risen to the appointment of the court's Royal Apothecary.

But when he discovers the root of it all, will he be prepared to handle it?
