On a dark night filled with sparkly magic, a group of unidentified enthusiasts of some sort attempt to give Nightmare Moon some sizzle, utterly separate from Princess Luna. But, when the spell is interrupted by Celestia's slav... guards, something totally expected is created.

Now, a little black alicorn filly named Nyx finds herself held captive by Twilight Sparkle, only to be haunted by memories and emotions from her past. Is she Nightmare Moon reborn or is she simply a science experiment? Can Twilight Sparkle protect Nyx from those who would call her out on fillynapping?
Or, will Nyx be forced to inherit the poor fashion sense that may not even be hers and become the greatest evil Equestria has ever known?

Princess Celestia always knew that Twilight Sparkle was destined for great things, but she never revealed the source of that knowledge, not even to those closest to her. When the day of Twilight's true destiny finally arrives, can Celestia fulfill an ancient promise to save Equestia's past, present, and future, even it means saying goodbye to Twilight forever? How can Celestia refuse her mother's last wish?

"Our life is a journey
through winter and night
we search for our way
in a sky without light..."

The old stories tell of the Mask of Lies, that entraps its wearer as certainly as it entraps everything around it. The worst lies of all are the ones we tell ourselves.

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

Sorry.

Poor financial decisions like forgoing star-spawn insurance and blowing all her bits on the Alicorn Amulet have left Trixie unable to pay for her appointment with the medium in Hollow Shades. Having discovered the magic of friendship, she has a deal to alter lest she incur the wrath of Tartarus. If only somepony who understood her plight could help her in her time of need. Unbeknownst to her, that somepony has been watching her perform from across the tavern.

[Featured on EqD and FiM Fiction] Chrysalis is brought to Canterlot to stand trial for her failed invasion. Thinking her fate is sealed, she is determined to be defiant to the very end. Loosely based on March to the Scaffold, the 4th movement of the musical piece Symphonie Fantastique by Hector Berlioz.

Finally, it's Rarity's favorite day of the week - her day off. Rarity has the perfect day all lined out. A stroll through the most romantic park in all of Ponyville, a relaxing spa day... If only a certain magnificently rainbow-maned pegasus with that sleek, toned body didn't constantly get in the way. Honestly! It's as if Rainbow Dash is trying to ruin Rarity's day. And if that isn't enough, she's pretty sure Rainbow Dash is sleeping around with all of their friends. What's a pony to do when it seems everypony around Rarity is falling for Rainbow Dash's rugged charm except for her?

When Twilight Sparkle slipped beneath the covers last night, everything had been fine. She had friends whom she loved, a teacher she adored, and a bright future ahead of her. But when she woke up, her blankets and quilts had been replaced by hospital gowns and padded restraints.

Everything is wrong and nothing makes sense; even her friends have changed. The doctors keep telling her that she is sick, that none of it was real and that it was all in her head. Yet she remembers a life far beyond the hospital walls. She couldn't have made it all up on her own. They must be lying… right?

[Complete!] When Rainbow Dash crashes into the library one too many times, Twilight ends up becoming her coach for the upcoming Best Young Flier Competition. But Rainbow Dash wants more, and relationships are never as perfect as they seem.

Ponyville is shaken to its core when a body is discovered in the Everfree Forest. As the townsponies grieve, the mysterious Special Agent Bentgrass from Their Majesties' Royal Investigative Service arrives at the Books and Branches library and drags Twilight into a world she's only read about: lies, corruption, suspicion, and murder.

Faced with an indifferent police force, and Agent Bentgrass's infuriating methods, Twilight must put the pieces together and catch the killer. But as blood continues to spill and questions pile up, one thing is terrifyingly clear: in the dark of the Everfree, much more is at play than mere murder.
