Twilight's life is changing very quickly and there is nothing she can do to stop it. Will Princess Celestia still look at her the same way? Will any of her friends? Is the pain worth it if they cannot accept her changes, or is it better to just join the starving?

A thousand years ago in Equestria, Luna's frustration and desperation has been building for years and years as her social and political isolation grows, but just before Luna's jealousy and resentment can turn into murderous hatred against her sister, a new event triggars Luna's mental collapse and pushes her over the edge. When Luna by circumstance finds herself alone in Celestia's room she reads her sister's diary out of curiosity and discovers all of the disparaging criticism that Celestia has leveled at her over the years about how much of a nuisance Luna has been to her, but has been too polite to say directly to Luna's face.

Luna and Celestia had always supported and stuck with each other all their lives. Even when the common-ponies critisism and shunning of her was at its worst, the knowledge that her sister loved her kept Luna going. The realization that nopony, not even her own sister valued her or thought she was fit for the throne completely shattered whatever remained of her fragile psyche.

And so Luna just gave up...

She gave in...

If no one wanted her there...

Then she wouldn't stay there...

She would leave.

Twilight Sparkle discovers that the alternate timelines created by Starlight Glimmer in her misguided attempt at revenge did not, in fact, disappear when the original timeline was restored. Instead, they persisted as separate, parallel universes.

Never one to leave a job unfinished, she decides to employ the magic of friendship to restore those universes to a more harmonious state.

She begins with Nightmare Moon.

What is friendship?

Is it a term or something so much more?

And can you be a friend to something so different but so similar to you?

Something that I'm sure has been done to death but, since reading East of Eden, I wanted to do something a little more thought provoking. I got the idea while I was alone in my house, with just the sound of a clock ticking to keep me company.

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."

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

This story is a sequel to Inexcusable

She looked just like Princess Celestia, except marred and broken. Her ceremonial barding had rusted slightly, and dirt matted her coat. Most noticeable was her hair; black streaks accompanied its usual multicolored luster. They looked like discolorations in an old photograph.

Worst was the scar across her chest. Her armor covered it, but nothing could hide what it meant.

The tarnished Celestia smiled at Luna. "H-hello, monster. I would say I am glad to see you, but that w-w-wouldn’t be quite accurate."

Out of sadness and betrayal, Amber Night flies off not caring where she was going until she eventually comes across the Castle of the Two Sisters and meets Nightmare Moon

(Featured on May 13, yay.)

If called upon by a ritual -
most demonic beings follow the call.
And on the other side of the magic stands -
a human being, in a trance.
Their wish will be heard and fulfilled for a price -
in exchange for a soul, demons play nice.

When a desperate person calls out into the void - what happens when the void stares back?
Lily Potter is a strong woman, but in the face of almost certain death, even someone like her can come to the conclusion to fight fire with fire, and call upon a demon to fight the inhuman Dark Lord tearing down her home.

Once called, Nightmare takes on Harry as her child... this doesn't bode well for the sanity of everyone else involved, especially once she finds a very special letter addressed at herself years later.

Disclaimer:
The Nightmare in this story is a (far) future version of the Nightmare found in my other story.
The 'Sex' tag is for roughly two sentences implying it in a chapter near the middle (hence this story's rating).
The 'Death' tag is for, well, the death of Harry's parents.

Whenever Luna asked Celestia to build a snowmare with her, they never seemed to have the time.

And then their time together was lost for a thousand years.
