After a mirror portal field trip being conducted by Luna goes terribly wrong, Ocellus finds herself trapped in a strange palace far from home. That palace, once abandoned, is now infested with a hive of love-starved changelings intent on using her only way home as a means to invade her world.

Otherwise, Ocellus appears to be alone.

At first.

The story is inspired by, and a homage to, my favorite game of the last decade. However, this story is neither a crossover nor AU. This story is set after "The End of the End" (but before "The Last Problem"), and is purely a My Little Pony story. Warning: rudeness and intolerance are not allowed in the comments, but spoilers are. Exercise discretion. Remain polite and on-topic. And please enjoy the story!

Twenty thousand years into Twilight Sparkle's rule, the burden of the countless trillions of ponies killed Equestria. Depleted, polluted, and dead, the planet was abandoned. The Goddess Twilight Sparkle and her alicorn compatriots led the surviving ponies to a new life among the stars.

Ponies advanced. They evolved, and grew. A golden age of peace and prosperity occurred that lasted for thousands of millennia.

But that was long ago. Before evolution turned against them, and before the deadly Mortality Virus raged through their ranks. Now, at the twilight of ponykind, their final hope is for a small crew to return to their long-dead and long-forgotten homeworld one last time.

Clover the Clever never asked for his life to get so complicated.  It was bad enough tricking a drunk Imperatrix Celestia, war goddess of the Three Tribes, out of her accidental coup against Queen Platinum.  But now the most dangerous pony in Equestria has returned to trade her claim on the sun for a chance to woo him.

On top of that, his erstwhile mentor Star Swirl the Bearded has saddled him with a mysterious magical necklace and a uniquely bleak and pointless prophecy: If he's brave enough, and if he's clever enough, he just might survive Celestia for long enough to break her heart.

Now with an audio reading by ScarlettBlade!

Recommended by PresentPerfect! "horizon gave me the story I needed rather than the one I wanted ... along the way we get some very strong lessons about love, and meditations on the value of a lifetime and what one pony can achieve on their own."

"To the top of the ballot with it." –AugieDog
"There’s going to be a lot of tears shed when this one hits publish." –Georg

"I can get behind some historical revisionism for such a brilliant story. The writing is second-to-none … I laughed, I cried, and I felt other things too." –Trick Question

It's not easy to go back to your life after a thousand years of insanity and exile. It's not easy for Luna to even leave her room. All the same, there's a special somepony that Luna desperately wants to get closer to, and that's worth facing the outside for. All she has to do is get up the nerve to talk to her.

The legend is known throughout Equestria, but there are few who believe. Those who claim to have seen the beast are dismissed as crackpots and madponies. Those who bring evidence before the world are dismissed as histrionic deceivers. There are those who have seen, however -- those who know -- and they will forever cry out their warning from the back seats of filthy, old train cars, even to those who dismiss them, who revile them, who ignore their warnings unto their own mortal peril.

"The sasquatch is real!" they will cry forevermore, even as nopony believes.

But from this day forward, Sassy Saddles will believe.

Written on a dare. I apologize for nothing.

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
