Princess Twilight Sparkle has granted her student, Starlight Glimmer, a few extra days in the mirror world to get to know everyone – and hopefully learn a couple lessons of her own along the way. With newfound friends like Sunset Shimmer by her side, she’ll have nothing to worry about while she explores the strange sights that await her.
...Right?

Takes place directly after "Mirror Magic", but viewing that isn't required to properly follow what happens here.

Proofread and Edited by ChudoJogurt.

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

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 isn't exactly fitting in at Canterlot High, but she's changed her ways and is slowly making amends for her past behavior, but she still hasn't grasped all the differences between pony society and human society--a point pressed home when another thing she's taken for granted changes in front of her very eyes.

Set between Equestria Girls and Rainbow Rocks

This story is a sequel to Expulsion

Sonata Dusk, once lost and unsure, is living proof that people can change. When she realizes how hard it is to make amends and regain the respect of her peers, she will make an attempt to do some good, so the students of Canterlot High could see who she really is.

Setting up a café sounds like a great start.

With the upcoming Friendship Games, Sunset Shimmer has been understandably distracted. That is until she spots Aria pass her by in the street. Curious to know what happened to her and the other sirens after the Battle of the Bands, Sunset follows Aria to an unusual destination, and has an equally strange conversation.

This is an interquel of 7DSJ Book I

Sunset Shimmer wants to be seen as your average teen girl. One who goes through extraordinary events rather often compared to most normal girls, but otherwise totally isn't secretly a magical unicorn from another dimension.

However, this image of normality she projects gets called into question when one of her adoptive parents happens to witness her buying...horse shampoo.

How will she get out of this hairy situation?

This story is a sequel to Foreign Nationals of Unusual Importance

A Twin Canterlots story—second in the Cook’s Tour series

What’s the reward for a job well done? Another job. Cookie Pusher, the junior diplomat keeping an eye on Sunset Shimmer and her friends, has pleased his superiors with his diligence and competence. Deciding he’s ready for bigger and better things—and not wanting to brief in yet more people about the portal—they assign him a new task: travel through the portal as chargé d’affaires en pied to open diplomatic relations with Equestria.

Takes place about twelve months after “Through the Mirror” and six months after “Rainbow Rocks”—early in season six.

Magic has slowly been flowing into the world. Ever since the appearance of Twilight Sparkle's crown in Canterlot High, more and more magical incidents have occurred. So far the Mane Seven has done their best to keep this contained but sometimes they are simply not available. Sometimes they can't be reached.

When an artifact is found by a student which has pony symbols and strange writing on it, its origin is obvious. Remembering whats happened before, the quick thinking student brings the item to Principal Celestia, and now its up to her to decide, how to handle this.

Sunset Shimmer has lost everything. All her so-called friends have turned their backs on her thanks to the machinations of Anon-A-Miss, and she's abandoned and alone. About to step out into a cold winter afternoon, she hears a voice she didn't expect calling her back...

Written because of my own temper and sense of righteousness has fouled my thoughts before. Written because we can see the truth of things even through our anger. And written because I'd like to believe that individuals can think beyond the baying of the mob.

Rated T for swearing, discussions of violence, and some other PG-13 scenes.

9/18/17- Featured. For a minute. A little stunned.
9/26/17- Featured. Again. Let's see if it will last...
10/2/17- Featured for a few hours this time. Thank you all!

Sunset Shimmer has been attacked and lies comatose in the hospital. All evidence points to someone who has access to magic. Led by Rarity, the rest of Sunset's friends begin to search for who did it and why.

But the answers may not give them the comfort they seek. And unknown to them, Sunset is having struggles of her own.
Part 1 of The Repercussions Trilogy.
