Sepia Tock is an artisan, friend, and citizen of Ponyville. He is not, however, Doctor Whoof.
This is his story

Nightmare Moon may have been defeated, but Princess Luna still struggles with her inner nightmares. It was so easy to give into the temptations of power the first time, now that she had a taste of it, can she give it up for good? Or will she return to her old ways and have to be banished again, this time forever?

Twilight Sparkle wakes from a coma after being cursed by a stallion she doesn't remember ever meeting. Princess Celestia and Spike have been taking care of her while she was sleeping. But something is wrong, and Twilight’s memories don’t match up with anypony else's.

This is an AU story of my own twisted imagination. Set after “Games Ponies Play” but before “Magical Mystery Cure” timeline wise (sort of, you'll see). So no Alicorn Twilight here. Tagged Twilight and Celestia as they are the main characters, but other characters do appear in the story.

Descriptions are hard. Big thanks to my Pre-Readers Nakrab and Dumbgamer99!

-- Soft Story

Celestia decides that Big Mac's barn is an excellent place to sneak off to, to take naps on her days off.
Big Mac decides that Celestia is a welcome guest.
Neither Princess nor farmer ever speak to one another, but the silence sings between them.

What would you do if you woke up one day to find an Alicorn Princess Goddess passed out drunk on your doorstep, unable to be awoken? Rainbow Dash certainly has her hooves full with this one. How is she going to handle this??

For most of Applejack's life, she didn't know what she was. True, she understood who she was well enough.
But ponies don't change shapes, nor do they get strength from love.
Applejack never thought too hard on it... until the events of a certain wedding brought about some harsh realizations.
Now, with Equestria still reeling from the surprise attack, will Applejack manage to come to terms with what she is? Will she even be able to keep her secret safe?
For if the royal guards don't get her first, the conspirators in the shadows just might...

This story is a sequel to Princess Celestia The Changeling Queen: Stories Behind the Mask

At the Royal Wedding, Chrysalis and the Changelings were revealed to all of Equestria.

But another mask was torn away that day. A mask born for a thousand years. A mask created on one promise. A mask, that has become synonymous, fused, to its bearer.

A mask that when ripped off, causes Twilight, her friends and Luna to question everything they ever knew about the one pony, one very important pony.

At the Royal Wedding, the meaning of the phrase 'Princess Celestia' changes forever.

NOTE: Chrysalis is NOT Celestia!!! That'd be impossible to pull off.

Now with a reading by Goombasa!

When facing Twilight Sparkle, Nightmare Moon was given a choice: redemption or revenge. What if she had chosen the latter? A grim fate awaits Equestria, but in a time of greater strife and conflict, Discord's return is accelerated. While he expected to bring chaos, he did not anticipate that he would end the Longest Night and bring hope and joy back to the land.

Discord struggles to reconcile his nature with his desire for admiration. While Twilight's friends strive to carve a new life in the ever-shifting Equestria, she searches for Celestia, the only one who can bring harmony back to her lands. But Nightmare Moon also seeks her sister in a desperate attempt to find her place in the world. New dangers lurk in the wild and more threaten to fall over Equestria. Nightmare Moon's decision broke the balance of the world. Will Equestria ever turn to peace, or will the spiral of chaos and destruction be the end of everything?

(An alternate history, this story takes the universe established by the canon and explores one possible outcome if Princess Luna had not been redeemed.)

Special thanks to my pre-readers, MmmandarinOrange and DarkmatterButterflies for keeping my head on, taking the journey of the story, and making it so much better than it would have been if I wrote it alone.

This is an idea that wouldn't leave my head, inspired by Fairy Slayer's "Mommy Nearest," Aldea Donder's "Alicorn," SoundofRainfall's "Play" and RainbowDoubleDash's "Lunaverse"

Alternate Universe: Instead of Twilight Sparkle, Princess Celestia made Rainbow Dash her personal student instead! Follow her through the events of the 1,000th Summer Sun Celebration. A reimagining of "Friendship is Magic"
