Twilight isn't having a very good day. An experimental spell blew up in her face, an army of changelings is attacking Canterlot, and she just died. Yet somehow, it looks like it's going to keep going downhill from here.

Given the chance to correct what's gone wrong, Twilight swears she's going to fix all this even if it kills her. Which it will. Frequently.

Note: This story was written during Season Two, so a few small things are out of date.

When Twilight Sparkle slipped beneath the covers last night, everything had been fine. She had friends whom she loved, a teacher she adored, and a bright future ahead of her. But when she woke up, her blankets and quilts had been replaced by hospital gowns and padded restraints.

Everything is wrong and nothing makes sense; even her friends have changed. The doctors keep telling her that she is sick, that none of it was real and that it was all in her head. Yet she remembers a life far beyond the hospital walls. She couldn't have made it all up on her own. They must be lying… right?

My name is Twilight Sparkle, and 350 years ago, Sweetie Belle and I vanished without a trace.
Now here we are, in the future.
Equestria has become a utopia, with everypony living in peace and harmony.
Everything is perfect. All a pony could ever want, and more.
My name is Twilight Sparkle, and I want to go home.

Spanish translation by Spaniard Kiwi

No pony is the same after witnessing a work-related death, no matter who they are. The victim was young, eager, fresh-faced, and recently hired. In his last breaths, he let out a scream so heart-rending that the employees who heard it had difficulty sleeping that night. And Rainbow Dash was no exception.

But she's not losing sleep over that. What disturbs her is something far worse—something she said afterwards.

"We have to be brave now, Scootaloo," Dash said. "Just close your eyes, and it'll be all over by the time you open them again."

When Rainbow Dash makes a startling revelation to Twilight Sparkle, it sparks a serious discussion about painful events in the past, what the future holds, and self-realization and the nature of destiny.

Featured on Equestria Daily on December 14, 2011!

"Equal parts heart-wrenching and beautiful. The author has managed to portray Dash in a way I never thought possible."
- EQD Pre-reader #R107

UPDATE: The final edition is written and published as of October 12, 2015!

The sequel to this story, Scent of Roses, is now complete!

The other sequel (although chronologically a prequel, technically), Born in Equestria, is also now finished.

Though the distance between Pinkie Pie and her five closest friends has grown in the half-century since they claimed their Elements, she does what she can to prevent the others from drifting away. It’s small things, mostly: tea with Rarity, a drink with Rainbow Dash, a few words with each of the others. The friendship still makes each day together magic, and she works as hard as ever to bring cheer to all of her friends. When the smiles come less frequently, that just makes each one that much more precious.

Something is eating at Rainbow Dash. Ever since the Royal Wedding in Canterlot, she's been quiet, aloof, and distracted. After a long day's work of shaping the rainclouds over Ponyville, she can no longer keep the truth bottled in. The only problem is, as a picnic with her close friends looms over the horizon, she's at a loss to find a pony she can comfortably share her thoughts with.

What are the chances your favorite pony was secretly a changeling all along?

Yeah, probably about one in one.
