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.

Tragedy strikes the Sparkle estate one winter evening and Twilight finds herself cold, alone, and far from home.

Fortunately she stumbles across two fillies who may have more in common with her than she realizes. With no place else to go, nopony else to turn to, and no clear way back home, Twilight decides to stay with the fillies and their caretaker while she tries to piece together the mysteries of what happened to her family and why.

Bonds will be forged.

Secrets will be unraveled.

And a great journey will be undertaken.

Additional tags: Sad, Slice of Life (I don't care if it contradicts the Adventure tag, things are gonna get Slice-of-Life-y)

AU in where Twilight is a dragon but still is Princess Celestia's student. Twilight has a more logical head on her shoulders and takes her job as a caretaker to Spike more seriously than canon.

motherly!Twilight, manipulative!Celestia

Idea sparked from Winter Quill's stories Growing Up With Scales and Sparkles and Scales

This story is a sequel to Fecundity

Mount Everhoof. Tallest peak in the world, jutting up to stab the sky like a tall, cruel fang. The mountain’s western slope has held a secret since before the three tribes were founded, but few who seek it ever return. Those that do always speak of a foul magic that attacks the mind—horrors brought to life, paranoia unending, and a blind, murderous rage that sets even family against each other.

In olden times, Princess Celestia and Princess Luna heeded their elders and forbade access to the western slope. That forbiddance continued after the rise of Nightmare Moon, for Celestia realized even alicorns can go mad. The last ones allowed passage were a team of ponies sent by Princess Cadance and Prince Shining Armor two years ago, and of the seven that set out… only one came back.

But the mystery may be on the verge of being solved. The defeat of Tirek has awakened a new power in the Elements of Harmony, one that can resist Mount Everhoof’s empathic magics. With the aid of Maud Pie’s expertise in geomancy, Twilight Sparkle and her friends now venture up Mount Everhoof in search of an artifact belonging to the late King Sombra. They’ve yet to learn what connections the Mad King had with the mountain, but they know they must locate the cursed artifact and destroy it…

...before it can cause any more harm.

Warning: The following story is currently unedited and contains some M/M shipping. If you don't like one or both of these, you know where the exit button is. This is an experimental piece that I'm working with.

Prince Blueblood's newest guards want to humiliate the Prince at the gala by slipping a love poison in his drink. After he consumed it, the Prince spontaneously falls in love with the first pony he sees. Unfortunately, it's Spike the Dragon.

A Metroid Crossover

A meteor, resistant to magical manipulation, crashes in Equestria, Planet Equis, and soon spreads an unknown poison throughout the land. Containment is all but failing and the Princesses have little power to stop the spread of the Great Poison. The Elements of Harmony are of little use as no knowledge exists of this threat that consumes all life. Help comes from a certain Hunter, clad in metal.

Samus Aran will not only fight for her life as always, but her own sanity as well as these ponies that she begrudgingly starts seeing as allies. New horrors and abilities await her as a reason to fight slowly festers within her, possibly unlocking something she had been denied for so long: Friendship.

Notes and Resources:

This takes place after Echoes. The events of Corruption will have not happened yet. In terms of MLP, consider everything up to and including the Crystal Empire. Princess Twilight does not exist here, etc. The official Metroid Timeline can be found here.

As well, this story references the manga in many places. Reading of it is not required and I try my best to explain the context, but if you're interested, both volumes can be found here.

EDIT: This story was written over two and a half years, beginning in 2013. You'll probably notice the difference in writing as the chapters progress.

The SCP Foundation, an organization that has existed for thousands of years, an organization that survived the near extinction of their species, an organization that has always been in the shadows, but will one slip-up bring them into the light?

What if someone wanted it to happen?
