Princess Luna must go on a diplomatic mission to the isolated city of Marem, and is tasked with choosing a suitable traveling partner to accompany her on the way. She does not choose the talented and magically-inclined Twilight Sparkle, nor the quick and loyal Rainbow Dash, nor even the strong and talented Applejack. Instead, she surprises everypony by taking Pinkie Pie with her and leaving without a word. Not even Celestia can guess the reasoning behind her sister's choice.

For whatever reason, Princess Luna and Pinkie Pie set off to find and negotiate an agreement with the mysterious community of unicorns located beyond the borders of Equestria. What they find there will impact not only Equestria's stance on foreign policy, but the very lives of the two ponies at the center of it all.

What if Rainbow Dash had been present when Discord gave the Mane Cast their first shot at him? How could things have gone different? How could this have changed things?How could this have changed Twilight?

Everypony has their secrets. Their own 'guilty pleasures' that they try to hide even from those closest to them. What kind of secret does Twilight Sparkle keep to herself, and can she indulge in it when she has the whole library to herself?

Twilight has issues with the new mare in town. Pinnacle is smarter, prettier, more connected and more talented than everyone combined. Why can't Twi love the gaudy newcomer with the contrived and complicated past? As the lone voice of dissent she finds the only possible solution; a sledgehammer.

Pinkie Pie comes to Rainbow Dash with shocking news; the world is going to end, and they have a million things to do before it does. Although Rainbow Dash agrees to play along, she obviously doesn't take her seriously... but as the day goes by, the true meaning of Pinkie's warning becomes clear.

When the light dims and the flame burns out, the magic inside us all will forever endure.

Ponies are disappearing on suspicious holidays. Pinkie Pie has a new cupcake range. And a cleaver.

Could these things possibly be related? Can Apple Bloom solve the mystery before it is too late? Or is it cupcakes for all?

It's lunchtime in Ponyville, and Twilight Sparkle's stomach is calling for something with a little more flavour than what she usually feeds it. How will she and her friends react, though, when the lavender unicorn discovers that there is no place in Ponyville where a pony can get a decent burrito?

She's clever, musically gifted, and the most talented DJ in all of Equestria. She's Vinyl Scratch and she had it all, anything and everything she's ever wanted. That may be just the problem though: life is boring. With a constant desire for excitement Vinyl finds herself no longer amused with her day-to-day life. That all changes however when she meets a mysterious creature.

It's a microscopic one-shot! This was written for StarmanTheta's weekly writing prompt, this week's prompt being "never enough pie."

It's too tiny to be described without giving up the ending.
