A mysterious shadow of the past and future is haunting the Doctor, using ponies as puppets to menace the time pony and impose its will upon Equestria. Weilding the lost chaos magic of Discord in six Elements of evil, will the Mane Six be able to defeat this new evil and its minions? Or will a dark and endless night cover the land forever? The story may be a touch confusing for non-Doctor Who fans, but I've put story notes in a points where the references get a little thick, but not where they'll spoil dramatic tension. A great deal of death occurs, but nothing of an overly gory sort.
