Old legends speak of a select group of ponies, linked by common ancestry and hidden in plain sight. Where they came from is a tale that dates back to before Nightmare Moon, and has its origins in a war beyond most ponies' comprehension. You've probably seen them without even recognizing them, thanks to their unique magic, but rest assured, they're on your side. They are known as the Order of Gallopfrey.

Quiver Quill and Lyra Heartstrings are among those who know of the myth, but the truth behind it is something they could only dare to imagine. But as time and magic shift around them and all of Equestria is threatened, they find themselves forced to grapple with that old mystery. Fortunately, they won't do so alone, as they find themselves dealing with a mad pony with a big blue box. Get ready, Equestria, because the Doctor is in.
