It shouldn't have been a big deal. Celestia was kidnapped or knocked out or just generally made to seem powerless by whatever idiot with ill intent decided to show up on a nearly weekly basis. As the mighty and immortal Sun Princess, she could escape at any time, but she was happy to play these little games. The daring rescues and bloodless battles gave her ponies such a sense of confidence and purpose!
But this one didn't go as planned. One small, stupid mistake got her thrown to the twisted reaches of the world-prison, Tartarus. Now alone, unarmed, and barely more than mortal, Celestia wakes in a living landscape where everything has every reason to hate her.
And, far worse, she has accidentally picked up a passenger.

Sidenote: This a repost (I tried to go through official channels, I promise!) of a story I wrote long, long ago on an account I foolishly deleted. Back in those days, Tartarus hadn't shown up in an actual episode yet. It's not exactly an alternate universe situation, but it has nothing to do with the canon portrayal of the place.

Rainbow Dash didn’t know she’d be on the precipice of the biggest change in her life when she nonchalantly agreed to help Pinkie Pie. Throw a party, make a lot of foals happy, go home. That was the plan.

So…why does she keep going back? Why does home…feel so empty?

Unable to shake the one foal that refuses to leave her head, Rainbow Dash is ready to jump into the greatest change—and greatest challenge—of her life.

And that, my friends, is only the beginning.

The Multiverse. It is a strange place in which there are worlds where things taste like purple and two plus two equals fish and if you divide that by three you get salmon... truly a weird place.

My memory is awful, but after moving around so much in the Multiverse, I had thought I had pretty much done it all.

At least, I thought I had. You see, the Multiverse is like that. It will lull you into a false sense of security, make you think you know what to expect and BAM! You’re a black kitten in a world full of ponies that are every color of the rainbow and the pet of a baby dragon...

Honestly though, this isn’t even on the top ten of the weirdest lives I’ve ever lead... I think.

Cover art was found on google, who ever made it is amazing and completely deserves all the credit. That person is not me, this is that person.

Discord is brought to Ponyville to be reformed. As a safety precaution, he is deprived of his magic before his release. Naturally, he is upset by this, but...
No one thought that the powerless spirit of chaos would actually run away! Twilight Sparkle won't let him get a way with it!

A word of warning: If you read for the Twilight x Discord, be aware that the buildup to actual romance in this story is extremely long. You will have to read for a long time before receiving gratification romance-wise. However, once it is established, the romance will be ongoing from then on.

My name is Twilight Sparkle, and I am a wraith.

A comment driven story following an alternate universe where Twilight is hundreds of years old, Sunset stayed Celestia's pupil, and everyone has the hots for Twaith. Okay, almost everyone. Lets see where this goes!

Thank you to TheStarsOfPines for the current cover art.

Here is the original, confusing, cover art.
Here is the second cover art that had been used.
The third! Done by the same as the current.

Ever since the Twilight Time incident, Twilight has wondered why the foals in Ponyville would be hesitant to approach her without an introduction, and learning that she is apparently the most popular princess from Sassy Saddles - despite not having seen evidence of it herself - only served to reinforce her concern that ponies were avoiding her due to her status. Her suspicions are confirmed when she attends a royal function and notices guests getting nervous as she draws near.

Twilight decides this needs to be addressed. Wacky hijinks ensue.

(Inspired by Appellation Mountains and Twilight Verbs Article Nouns. The concept could almost be considered a mashup of the two.)
