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
"One of my all-time favorite pieces of fanfiction." –brokenimage321
"My favorite EQG fic of absolute all." -Skywriter

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

Probably the best thing to happen in Discord's long life was finding the magic of friendship. As much as the old Chaos Lord might complain, without it he would never have found so many that were dear to his heart.

When that heart finds itself empty, he comes to the Princess to ask a favor: allow him the opportunity to bring friendship to other dark hearts. All she has to do is lend him a statue.

The rest is in his chaotic claws.

Death tag - no horrible murder, just a few mentions and the natural consequences of time.

Pinkie Pie is visited by a strange customer whilst working at Sugarcube Corner. Hilarity ensues.

Twilight Sparkle has been living a lie. Everypony told her what a beautiful and accomplished mare she was. Everypony thought she was a responsible adult. They were wrong. She was still just a filly trying to stumble her way through life.

My name is Lottie.

When my Grandpa died, I never expected any more really drastic changes in my life. Maybe I would've been more prepared.

Clues and whispers aren't going to be enough on their own. Sometimes you just have to get your hands dirty, set things in motion yourself, no matter how weird they get.

And boy, do things get weird.

And on a completely unrelated note, word on the street in Ponyville is that there's something in the woods.

Takes place between seasons 3 and 4. I starting writing this a long time ago.

Strongly Recommended Stories:
The Brightest and the Best by Pineta - The events in this story are considered to be completely canon to this timeline and explain Twilight's entrance exam to Celestia's School for Gifted Unicorns. I cannot recommend this story enough.
MLP Annual 2013 - "The Fall of Sunset Shimmer" - As above, the 8-page short comic in the beginning of the Annual is also considered to be canon, though with some major variations.

Version 3.0 Edit: Extensive grammatical and mechanics changes. Adjustment to timeline of Sunset's second mirror experience.

Bon Bon's voice is funny, and that's about all that anypony who meets her notices, as her marefriend Lyra soon steals the spotlight with her explosive personality, strange obsessions, and curious beliefs. And why not? Bon Bon is, after all, a perfectly ordinary, boring pony in every way but two: her voice, and the carefully kept secret that she isn't really a pony.

(Edit:) Now with an annotated version, courtesy of the incomparable Shoggoth Lord!

Idol Hooves holds a special place in Equestria. He's probably the only exiled changeling to serve in the Royal Guard, or at least, that's what he expects, as exiles don't really broadcast that fact. However, it's well known that Princess Celestia loves all of her little ponies, and her guards perhaps more so, and that makes it one of the best ways for a changeling to discreetly feed.

But how does a changeling even get there, let alone get exiled in the first place? For that matter, why would it ever go to Canterlot? Set a number of years before the series proper, before Luna’s redemption, Idol details how he was exiled, the ponies he’s met, and the series of misadventures that led him to joining the Royal Guard, and should continue a good ways into the series, as something of an alternate perspective.

Soon, he’ll have to deal with a boisterous new princess to serve and a royal wedding in the works bringing a third to power. Will his old instincts bring this new life crashing down around him? What precipitates Chrysalis’s ill-fated assault on Canterlot? Is it really so wrong for a changeling to enjoy good craftsmanship to an obsessive degree?

This story is a sequel to Twilight gets a Puppy

Meet Rahs Sparkle, Moon Dog, Thespian, unexpected brother of Twilight and Spike Sparkle, even more unexpected grand pup of Princess Luna, and current target of the pink boat horse's nautical nonsense.

Join the Sparkle siblings as they deal with Chaos, live through Nightmare Night , survive the CMC, deal with charlatans, giants, dating, and the wedding of the century.

All somehow without strangling each other, or their friends.

[ Despite having to tag the story with Gore it is light on that. It is however somewhat heavy on innuendo and lewdness, but there's still no tag for that.]

[ It would also be good if you read the first book as it ties directly into this one.]

[ LINK TO SEASON 3 ]

When Twilight Sparkle had the magical surge that cemented her place as Celestia's student, the amount of power she released not only hatched a baby Dragon, it brought forth something else. Something that shouldn't exist any more.
Something that has Celestia worried.

A fluffy puppy.

[Despite the gore tag it's rather light on that, and they have yet to make a lewd tag and there's a bit of that.]
