Twilight questions who's journal she's reading and ends up having a talk with Sunset Shimmer.

After that, Sunset and 'Twilight', become friends.

When Sunset Shimmer left Celestia's tutelage, she entered the magic mirror that had shown her dreams coming true, but instead of ending up in a simian mirror-version of Canterlot, she ended up in a strange school of magic, an esoteric, arcane, and clumsy kind of magic, but a potent one nonetheless.

Disoriented, and her mission somewhat derailed, Sunset is nonetheless determined to become an alicorn. She has glimpsed eternity, and will continue to pursue it. Whether the magics of the school of Hogwarts will aid her or not remains to be seen.

Put simply, this is my attempt at making a power fantasy entertaining. Read more about it here.

Thanks to ssokolow for his help with the story.

Principal Celestia always has wings in her dreams.

They got her into trouble, once. She let herself believe that they meant she was an angel. Then she grew up, and learned some hard lessons about what being an angel really required.

Now six magical girls have just fought a demon in front of her school. And her phantom wings are itching.

Her life is turning upside down ... and she hasn't even heard about Equestria yet.

Rated Highly Recommended (Top 15 Stories Sitewide) by Present Perfect! "It's f**king flawless, you guys. … The first [6]00-word chapter by itself is a masterpiece."

"Literally the single best EqG story on the site." —Professor Plum
"[One] of the best stories on the site, period." —Pearple Prose

Rated Why Haven't You Read This Yet? by PaulAsaran! "I might have been skeptical going in, but horizon knocked it out of the park."

Rated 5/5 by csquared08! "The opening chapter here was truly something else. ... Then I hit the end of chapter 3. holy crap."

Rated ★★★★ by Louder Yay! "A lesser writer might have made a horrible, cliché-ridden mess of this story, but fortunately horizon is not a lesser writer. For a start, it's by some distance the best portrayal of the human world's Celestia I've read."

Third place in the "Under the Sun" June 2017 Writeoff!  (That first draft has been revised and expanded for FIMFiction.) Praise for the Writeoff version:

"Holy cow ... That's how you write an EqG fanfic! You captured the heart and SOUL of this/your version of Principal Celestia, wrapped it up in bi-universal consistency, and sold me on an idea of redemption I didn't even know I needed." —Xepher

"This is gorgeous. A thorough, exhaustive, incredibly moving portrait of a character who I don't think I've ever seen get quite this much development or attention." —Posh

"This is actually, after all these years, an original take on a story on Luna's banishment. If that's not something to be celebrated I don't know what is." —Quill Scratch, Radio Writeoff

Sunset Shimmer is having the worst day of her life. She used to be important. She was the personal student of Princess Celestia. She was a future leader of Equestria. She was the kind of mare that everypony envied.

Today, it's all crashing down around her.

Alternate Universe: What if Sunset Shimmer hadn't gone through the mirror?

Losing a child is the most terrifying thing that can happen to a parent.

Sunset Shimmer had been gone for years. Celestia had never really given up hope that she would see her again, but the doubt had always been in the back of her mind: what if she never returns? The echoes of their last fight followed her all those years.

And now that Sunset Shimmer has returned, Celestia wants to see her again. She has an offer to make, to a filly she raised as a daughter.

Everyone knows that Russia is shifty at best and about as reliable as back alley surgery. I mean, that's been a given in our world since Ivan the Terrible was around. Unfortunately, the Princesses of Equestria haven't exactly learned this lesson, and have left themselves terribly open to a cyber attack launched by the Russian Federation.

But what exactly is Putin after?

Currently relevant, absurd pony political satire. Teen for hidden innuendos.
A number of links are provided in-story at relevant points. Be warned, a significant amount of political flaming (biased against everyone equally) within.

EDIT: Featured 1/2/17! Thanks so much!

After sacrificing her life for another, Trixie was meant to receive admission into the shining golden fields and silver city of Elysium. Instead, she was waylaid while crossing the river of Oblivion by Rarity Belle, her promised after-life wrenched from her hooves, tossed in front of a pair of unsympathetic gods, and summarily dismissed. Now trapped in the fabled City of the Dead of Tartarus, Trixie will need all her wits and skills to find a way to escape.

Even greater trials await Rarity. Mind fractured by the nature of her death at the hooves of a fallen goddess, and then eroded further by the river's waters, she wages a war within as well as without. To return home she will have to first reforge herself.

Former enemies, they will need to learn reliance on each other to cross the myriad worlds, from Tartarus, to Gaea, and realms between and beyond, in order to return home.

A Myths and Birthrights side story.

Tirek had returned and this time there was nothing that could be done to stop him. The Elements of Harmony had been defeated, the Tree of Harmony had been ripped from the ground, and every spell that was thrown at Tirek was useless. It was only a matter of time before he found the alicorns and then all would be lost.

What happened next though, nopony saw coming.

Now with a Russian translation, which can be found here.
Big thanks to Armorer.

Luna discovers a lone member of the Royal Night Guard stationed beneath her private balcony. As a question becomes a conversation, as an evening becomes a week, and as an annoyance becomes a friendship, an unfortunate truth looms large in her mind: nothing is ever as it seems, neither in dreams nor reality.

She really, really is.

And Twilight has to deal with it.
