Description: The story follows Doctor Whoof as he embarks on an adventure to save Equestria from the evil which he accidentally summoned there when he crossed the gap between realities in his TARDIS. Along his journey he acquires the aid of each one of the mane six characters. They each become a Doctor's so called companion, but for only a brief period of time. As the story progresses, more and more is learned about an ancient artifact that every civilization has to call 'The Source'. With the help of our pastel colored equines, the Doctor will not only protect 'The Source' from those who wish to use its powers for evil, but learn more about what kind of a role the object played in the history of Equestria.
