Of all the possible dimensions, planets, and places the Doctor had explored throughout his years of existence, none were quite like the pony-populated Equestria. A world of peace, harmony, friendship, and so much more. Long-since adapted into his equine-shaped twelfth incarnation, the Time Lord has come to accept this pony-filled land as a second home. And as such, he has sworn to protect it from whatever danger may occur.

However, trouble is beginning to brew on the horizon. The TARDIS is damaged after a rough voyage, and an attempt by Twilight to fix it only results in more problems for the Doctor to solve. Not only that, but it would seem that the TARDIS has had a few curious pony stowaways. But rather than throw them out, (or letting them simply leave) the Doctor decides to bring them all along as his new companions. And not a moment too soon, as a new danger from beyond threatens to uproot the very foundations of Equestria... that is, the foundations of its past!

Can the Doctor and his 'crew' stop the alien threat? But how can they do that if the enemy can bend even reality itself to their will? Should everypony have just stayed in bed today? The answers lie beyond the mysterious Nth Dimension...

On-hiatus until further notice, unfortunately. As one of my earliest stories, it's in serious need of some fixes, anyway.
