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.

Super amazing cover art by Cold In Gardez.

Have you ever seen a pony that just seemed out of place? Perhaps some mannerism, some behaviour that just struck you as odd? Some piece of clothing that didn't seem quite right? perhaps a coat or mane whose colour just seemed flat-out weird. A strange build, a strange voice, or maybe they were perfectly normal, except that you swear you just saw the exact same pony not five seconds ago somewhere completely different?

Of course you have. Everypony has encountered an Outsider at some point. But never up close, it's always at a distance, and they're always gone before you have the chance to challenge them.

But sometimes the rules get broken. Sometimes fate gets distracted for a moment, and a lone unicorn mare gets to see something that she was never meant to see.

Twilight Sparkle's day is about to get very weird.

Special Thanks go to Horizon for initial proof-reading, editing, and signal-boosting, provided as a prize for spotting an Easter egg in his story Hard Reset II. Seriously, it's an awesome, brain-warping story and you should go read it right now.

Thanks also go to my editors for putting up with my atrocious grammar and spelling errors - Ganelon, Ephraim Blue, BronyWhooves, Commonancestry, Princess Autumn Forest, and Morning Sun
