Sunset Shimmer knew she was better than the other ponies around her, even if she didn't have her cutie mark yet. She had to be.

She just needed to find a way to prove it.

Twilight Sparkle: perfect student, lives in Ponyville, has great friends, and the newest princess of Equestria. That was her life before the tragic event happened.
She is transported to a new universe where she never met her friends and lived alone in darkness. Alone in a new universe with some memory problems, Twilight must find out who she is, before losing herself entirely.
...
Life in Equestria was perfect for Rainbow Dash. Her mentor, Princess Celestia, has given her a lovely home in a town called Ponyville. She and her friends helped keep harmony in Equestria by restoring Princess Luna to her rightful place as princess of the night.
There have been no problems in town, until a strange alicorn appears and claims to have no memory of anything but her name before appearing.
Rainbow, along with a strange stallion named Blue, wish to help her, but how can she help somepony who doesn't even know who they are themselves?

Twilight didn't know what came over her. At one point, she was having a wonderful tea party with her friends, and the next thing she knew, she was trying to kill the princesses.
This could have something to do with the fact that nopony would listen to her at her brother's wedding, everypony thinking she is crazy, or even the fact that Discord was set free without anypony noticing.
She finds herself at Celestia's court, facing crimes she didn't commit.
"Twilight Sparkle, for stealing the Elements of Harmony, attempting to kill me and Princess Luna, and Betraying everything you were supposed to protect, you are hereby banished from Equestria, never to return!"
Celestia's words continued to ring in her ears as she followed the road out of Equestria. She would never see her friends again.

This story is a sequel to The Luna Cypher

Twilight sets out to learn more of the ways of the world, and soon decides that the whole planet is disorganized, insanely dangerous, and desperately needs to be fixed. And she's just the mare to do it... with a little help from her friends.

Also, there are sky-pirates!

Book 3 of the Alicorn Adventure series.

A few extra, slice-o-life chapters are here: On the Rocks

After meeting a strange merchant in a convention, I thought my life couldn't get any weirder.

Now I have my favorite video game character's powers and abilities. I have a full powered Varia Suit with all the upgrades from Metroid games without the other appearances. I have combat knowledge I never had before. I even have a talking hunter-class gunship to live in.

Well, I guess I should protect others, not like Equestria needs bounty hunters right?

This story is a sequel to Princess Celestia: The Changeling Queen

This story is a direct sequel to Princess Celestia: The Changeling Queen. Reading that first is necessary to understand any part of this story.

Co-authored by vren55 and Zervziel

Alternia, sister to Chrysalis, ruled Equestria for a thousand years, disguised as Princess Celestia, while the alicorn slumbered in a healing sleep. Now revealed, Alternia prepares to become Equestria’s first changeling princess, and prove herself to the ponies she loves at the side of her co-rulers Luna and the newly-returned Celestia.

But even as the crown descends onto Alternia’s head, something is stirring in the depths of the Eastern Sea, something that will turn the surface world onto its head. Some power that could destroy Alternia, and all that she loves, before she can even regain the approval of her own ponies.

Will Alternia restore the trust her ponies once placed with her? Will she found a hive? Will she find love?

All that is certain is that Equestria, and the world, will never be the same again.

Now with a TV Tropes page.

Crossover tag for The Final Showdown

Were.

Years after the tragic accident that tore them apart, Twilight is determined to move on from her loss, and she sets off on an independent research project to investigate the strange happenings at Canterlot High. Little does she know that she will soon come face to face with what appears to be a literal ghost from her past.
