There's an old book that's falling apart. Twilight wants to copy it down to preserve it. But it needs to be as accurate and precise as possible, to preserve the state of the original. That shouldn't be too hard. After all, it's not like the text will change whenever she looks away.

Right?

Daring Do cannot believe her luck when she is asked to help explore the most ancient tomb known to ponykind. But terrible danger awaits her, for beneath the earth rests something beyond equine understanding.

It’s been a long millennium, and the Princess of the Night is picking herself up off the ground. She’s been getting closer with Celestia, and she’s finally learning to rely on her emotional support. They are able to talk more openly than they have in centuries.
But a feeling of sadness remains that Luna hasn’t mentioned, one that’s haunted her since her foalhood. She denies its existence as best she can, and certainly won’t talk to Celestia about it. She doesn’t know what it is or why it’s there. Perhaps the time has come to find out.
A transgender narrative. Contains depictions of dysphoria; I tried to be as true as possible to my own experience, but some may find it upsetting.
It has been a long time since I have creatively written like this. So, I'm rusty. Please criticize my work if there is something about my writing that you don't like, and don't worry about sparing my feelings. I want to improve and, if you'll pardon the pun, get back on the horse.

It was incredibly rare to find a pony so pathetic and deprived of love and affection that they’d turn to somepony like him for comfort. Love, Stygian realised, and everypony’s selfish desire for it, had bestowed him with a sense of normalcy.

Note: In this story, a little bit of darkness is still in Stygian, becoming some sort of a negative second personality that influences him.

Twilight Sparkle's Harmony Project is the culmination of her life's work. The only thing left is for everyone to be gathered, so that all of Equestria can join together in Harmony.

But now that success is staring her in the face, Twilight begins to have doubts. Fortunately, she has a friend like Discord, who is only too happy to lend a paw to a friend in need...

Twilight Sparkle has walked the wastelands for a very long time, but now, at last, he has reached the end of his journey. He only hopes now that the gods will listen to his prayers, and finally allow him a good place to die.

(Please read the story before commenting on the description)

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.

Before she left, Twilight told Applejack not to open the door. But when leaving the door shut means compromising her values, how long can Applejack hold out?

Written for the December 2014 writeoff: "Behind Closed Doors"

Side note: I've done some general edits and (hopefully) improved the ending. [26/02/2015]

After recovering from a perilous fall off of a building, a stallion is reunited with his best friend from his foalhood.

After a magical mishap renders Rarity temporarily blind, Twilight Sparkle agrees to help her around the Boutique, utilizing a fancy spell that allows Rarity to see a simple outline of the world around them. It's just a gesture of good friendship; absolutely nothing more.

Nothing more whatsoever.
