It was a night that will forever be burned into the memories of everypony. One fateful night in Equestria everything changed. The princesses who had ruled over the world with kindness and heart were gone, and a new ruler had taken their place.
Years have passed since that event. Ponies have grown up, aged, and moved on with their lives. Equestria has become a very different place over the span of these years.
Our story begins when a face resurfaces in Equestria. When a weathered, scarred, but familiar face steps into the light.

This is the fanfic based on Astringe's Bad Future series on DeviantART. He did some great designs of the characters, so make sure you give that gallery a peruse before you read the fic.

Also worth mentioning, he's been nice enough to plop any pics he does based on chapters I've written into this separate gallery, so there will be less spoilers for readers just jumping in to the story.

NOTE: The canon of my story picks up at the start of Season 3, where it begins to diverge away from the canon of the show. I've never read the IDW comics nor have I seen Equestria Girls, so the events of my story aren't canon at all with them.

Traveling between parallel universes is impossible, especially during the process of regeneration, but the Tenth Doctor doesn't have time to question the facts. He's just been thrust through a tear in the fabric of reality, gotten a new body, and landed on a planet called Equestria. Specifically, he's landed in the worst possible place in all Equestria – somewhere that's ready to unleash a “big ol' storm of chaos”.

That's just the beginning of the Doctor's strange new lease on life: there's a whole host of mysteries to explore. Who is Derpy Hooves, the gray pegasus who understands more about him than even she knows how to explain? How does Princess Celestia already know him? And what's the truth behind the Order?

Above all, the Doctor needs to discover if this new universe can heal the wounds he suffered in the last. Only one thing is certain: there's an awful lot of running left to do.

(Warning: For those of you who haven't watched up to the Doctor Who episode 'The End of Time'... spoilers. Also, this story begins between Seasons 2 and 3 of FiM, and things start to... diverge from there.)

Side stories can be found at The Merely Mundane Tales (of a Mad-Pony in a Box).

Death. When one is faced with the idea of it, it both terrifies and allures us. But in the case of one Grape Vine a corrupted lawyer who meets her end she meets death and has been chosen for some reason to take up the mantle of the grim reaper. See through the eyes and feelings of her as she deals with both her new job and what its means to be death.

Trees shorter than they should be, buildings smaller than preferred, a world filled with creatures bigger than him, yet others are near microscopic from his perspective.

Trying to find out where he should fit in is hard, because he is not too small, but most definitely bigger than most. Once he connects to the dominant civilization, a whole new world of opportunities is revealed before him.

He will walk as a giant. He will walk with giants. He will walk alone.

After thousands of years of ruling over Equestria and the umpteen amount of changes in social structure over that time, Celestia and Luna discover that they do not understand their subjects as well as they used to. After all, it's been several millennia since they were like every other average pony.

However, that's about to change when an eavesdropping Discord comes up with a "brilliant" idea.

How will the lives of the two sisters change? Will the lives of their new personas "Color Craft" and "Lyrical Rhapsody" be better than their old ones? Will the friends they meet along the way be too good to leave? And most importantly, will Discord ever be pretty?! No, probably not.

She snaps hard.

Princess. Alicorn. The pillar of all ponykind, against which so many ponies often judged themselves. Celestia hates having to constantly be these things, and it's past time for a break. Luna will watch over Equestria while her sister is gone, but taking a break from your duties and taking a break from how the world sees you are two very different matters. Enter Prominence, a quiet pony who nopony really pays much mind to. Perhaps because she doesn't exist.

Aided by this disguise, Celestia will find her peace and relaxation in the home of one of the few ponies who know Prominence's true identity: Princess Twilight Sparkle. But when Twilight begins to see Celestia as a pony, and not a princess, can she deal with the feelings that arise? And are the feelings for Celestia, or for a pony she knows is not actually real?

EDIT: I've been featured, July 19th, 2014. I have no words to express how terrified and humbled and terrified and proud and happy and terrified this makes me.

This story is a sequel to Project: Sunflower

After the events of Project: Sunflower, Erin Olsen has returned to Ponyville, happy to pursue her studies in magic. After everything that happened the year before, she's looking forward to spending her days studying and having fun with her friends.

Meanwhile, on the newly discovered world of Harmony, humans and ponies work together to study this strange new world. However, their arrival causes something ancient to begin stirring. Something that may end up changing everything.

Erin will need all of her courage, all of her cleverness and, of course, all of her friends to see herself through what happens next.

As a result of this, Button's greatest secret comes to light — but it's not the one the Crusaders were expecting to hear...
