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?

After many a thrilling adventure the Doctor drops the girls off in Ponyville to relax and recharge. But then Rarity's latest client, a diamond dog mining magnate by the name of Zeitgeist Stardust, shows up to announce that he'll have to cancel his order for a new ensemble for the Grand Galloping Gala... but as compensation, he's offering Rarity and her friends a trip to the fabulous Dragon Valley Resort!

There's no such thing as a free lunch, though, as there's trouble brewing in the mines beneath Dragon Mountain. A race of creatures known as "Grundels" are sowing disaster and trying to sabotage Stardust's operation, for fear that the digging will awaken an ancient evil. Are the Grundels' fears justified, and can the Doctor and his new companions put a stop to this?

This story is a sequel to Days of Wasp and Spider

Believed dead by their creators, the ponies that will become Celestia and Luna have broken their mental conditioning and escaped into the wilderness. Here they plan the revolution that will free all ponykind, knowing that it is only a matter of time before their ruse is discovered.

Back in their underground arcologies, the ponies' erstwhile masters deal with the consequences of the escape, all the while unaware that something lurking at the bottom of space-time wants them all dead.

SF (canon species only; no humans) Ponies were magically and genetically engineered to be the perfect servitor race. They are powerful, adaptable, intelligent and completely under the control of their creators. A laboratory accident frees one such pony from her mental chains, but how can one mare save herself and the rest of her kind if she doesn't even know she's a slave?
This is not the Equestria you know and these are not your little ponies... not yet, anyway.

A Soot-Covered World, book 1.

Monster attacks. Crime. Illegal hallucinogens made from electric fruit.

They say things didn't use to be like this. They say things were different, before Luna came back 60 years ago, but Detective Hard "Hardy" Boiled of the Detrot Police Department has never known any world other than that demarcated by the seedy streets of his beloved decaying metropolis; a world in which the coroners sing and dance, surveillance bugs have personality disorders, and the Chief of Police is a scarier entity than most of the eldritch things the city attracts.

The grey unicorn who turned up dead outside the posh High Step Hotel seemed like just another case, but her missing horn is the pointy tip of a very large and nasty iceberg. It's up to Hardy and his friends - a rejected monster hunter, a psychic cab driver, and an underground antiques heir - to find out what’s going on in an investigation that promises to stick more than a cupcake into the very eye of Detrot.

Especially if Hardy has anything to say about it.

The most wanted mare in Equestria, Twilight Sparkle is the greatest thief in the world. As she follows in the hoofsteps of her grandmother, Twilight Twinkle, she's joined by friends and chased by family, all while trying to make a few bits!

An alternate universe fiction where Twilight Sparkle never entered Celestia's School for Gifted Unicorns. At least, not without a set of lockpicks. Gilda is her closest ally and friend, and a skilled marksman with her crossbow. And of course there's Rarity Belle, who can wrap Twilight around her hoof with a wink and a smile - and usually picks her pockets in the process. With friends like these, Twilight keeps one step ahead of Shining Armor and tries to get her hooves on all the bits she can carry.

This story is a sequel to The Twilight Enigma

More of a mid-quel than a sequel, really. A Slice o' Life which takes place somewhere in the middle of Chapter 22 of The Twilight Enigma, and demonstrates that quiet enjoyment may be found in the middle of desperate adventures. Even pirates need to kick back and relax sometimes.

This story is a sequel to I Don't Want to Grow Up

Celestia was a filly living on an isolated farm with her sister and harboring dreams of greatness. Chrysalis was a black goo poured out from a screaming wound in the walls of reality, with a weak grasp on the appropriate amount of fangs one should have. Friendship was inevitable.
