Leave it to Twilight Sparkle to create the greatest spell of the past century – and then want to destroy it.

It's too dangerous to use, she says. It's too tempting. It can't help you the way you think it can.

Well, Starlight Glimmer knows a thing or three about temptation. She'll prove to Twilight that this spell – this magnificent book – is too important to destroy. That it can help ponies.

She just has to survive using it, first.

Second place in the May 2018 WriteOff.

Cover art is "Reformed" by Okaces.

There are a number of compounds the human body is incapable of synthesizing; these are found only in red meat. To save a dying human, Twilight asks her friends - except for Fluttershy - for advice.

My name is Twilight Sprinkle, and my passion is donuts—from the delicate morsels I serve at elegant cocktail parties to the hearty pastries enjoyed by hard-working ponies who get up early. I don’t have friends, I don’t have books, and I sure as the sun don’t have any wings. I don’t care whether you’re here for revenge, for romance, or for a favor. My name is Twilight Sprinkle and I’m not who you think I am, so either buy a donut or get the hay out of my store!

(Edited by the mysterious the masked ferret.)

We all know the story of how the Princess’ young student and five friends defeated Nightmare Moon and brought Princess Luna back to our lands. But what if the tale were false? What if the young Twilight Sparkle on the event of her entrance exam had not been rescued by Princess Celestia, but instead lost her mind among the power of her youthful surge and had to be sent away, far away before she could destroy all of Canterlot with her newfound power. Now the feral unicorn prowling the Everfree Forest only vaguely remembers her past, slipping away from constant terrifying attempts to capture her.

And she is beginning to remember what true power felt like.

Floydien remembers.

Twilight Sparkle is returning to the Crystal Empire for the one-year anniversary of Sombra's defeat. The whole kingdom is preparing to celebrate.

But four crystal ponies are preparing a different celebration. The pieces are moving, and their plot is almost complete – Lord Sombra's last, most faithful servants will have their revenge. Twilight Sparkle and all her filthy kin will die.

Now, in the final hours of their plan, something has gone terribly wrong. One of the four is a traitor. Everything is in jeopardy. And once again, the fate of an empire will be decided at the Gate of Heavenly Peace.

North of Canterlot, in the far marches of Equestria near the border with the Griffon tribes, there is a mountain that flies.

West of Canterlot, beyond the Galloping Mountains and a desert painted in the pastel hues of a faded rainbow, a tower sits at the edge of the world.

South of Canterlot, past the Everfree forest and the desolate badlands, a city of gardens waits to be born.

Buried beneath the Dragon Lands, there is a city. It rots, and it bleeds.

And it breathes.

A writing exercise inspired by the magnificent Lost Cities, written by Cold in Gardez.

Enormous thanks to Undome Tinwe, without whom this story would probably not exist.

How do you kill a pegasus's soul? Put her in charge of the town's weather, then only let her schedule sunny days and gentle evening showers. Not thunderstorms, not blizzards, certainly not hail or tornadoes.

Nothing fun, in other words. Celestia forbid the weather team make some real weather, the kind Rainbow Dash dreams about. The farmers would never stand for that.

Well, screw the farmers. Screw the fashionistas and screw the library princess too if she complains. Rainbow Dash has a dream and she's going to share it with the world, whether the world wants it or not.

A story dedicated to anyone who's ever been passionate about something.
