Based on a true story. Kinda. Not really.
A man named Jason previously led a rather melancholy life before he died violently. No surprise there. But as he wakes up in Equestria and is thrown into a foreign body, he is forced to survive with the guise of a changeling. Taking place shortly after the failed changeling invasion of Canterlot, how can he keep from being revealed by new security measures, and blend into this new world, while making use of the most unlikely of allies? But of course, avoiding ponies only turns out to be the easy part when trouble has a habit of reading its ugly head. Really though, what could go wrong?

Props to the ever epic Zubafa for his cover art.

A creature of old has been present in Equestria since the beginning of the rule of the alicorns, watching, waiting. He saw their fall and the sisters' rise to power. Now, for the first time in eons, he steps from watching and takes action.

Cheerilee wants to teach. Ditzy Doo wants her family to stop thinking she's crazy. Lyra just wants Cheerilee. During their first semester in college a sheltered rich girl, a budding engineer, and a street musician will each have to face the decisions that affects the rest of their lives. Will they be able to stay friends? A School Daze/Three Whooves standalone prequel, and the perfect place to start.

Labelled 'Crossover' for Doctor Whooves as a cast member.

A series of moments from Derpy's life, most of them less than cheerful.

Sorry.

Looking back, it should have been obvious. It wasn't at the time of course and they knew that, but it was now. All those brief moments they spent together, the close encounters, it was like they were dancing around the subject.
And it all began with something so very small.

Set during season two.

How can Celestia refuse her mother's last wish?

A short trip to Canterlot with Rainbow Dash and Applejack is the perfect opportunity for Twilight to test out her new long-distance Teleportation spell. But a nasty cold dashes the hopes of a quick trip, and makes the spell disappear in smoke: instead of arriving in Canterlot, the three find themselves in the nearby Everfree Forest, and discover that their location is not the only thing that went wrong.

While Rainbow has exchanged her wings and tail for a straw blond tail, Applejack has acquired a rainbow tail as well as a pair of strong, blue wings.

While Twilight attempts to find a spell to return the body parts to their rightful owners, the others must attempt to deal with this situation... and with their changing feelings.

On a dark night filled with even darker magics, an insane cult attempts to give Nightmare Moon a body and life of her own, utterly separate from Princess Luna. But, when the spell is interrupted by Celestia, something unexpected is created.

Now, a little black alicorn filly named Nyx finds herself living under the care of Twilight Sparkle, only to be haunted by memories and emotions from her past. Is she Nightmare Moon reborn or is she simply a doppelganger with a soul and mind of her own? Can Twilight Sparkle protect Nyx from those who refuse to see past her dragon eyes and black coat?

Or, will Nyx be forced to inherit the sins that may not even be hers and become the greatest evil Equestria has ever known?
