This story is a sequel to Steel Solstice

Continued in: My Little Apprentice: Apogee

Twilight Sparkle learns that the trust and goodwill of the Princess isn't always a good thing as she's given the trust of an important assignment. When that assignment turns out to be long-term, how will she handle taking care of a filly of her own? How will she handle this strange new filly, who proves to be much more than she appears. As a matter of fact, she seems to be from an entirely separate universe.

Meanwhile, Second Chance has kept only enough of her memories to know that she isn't what she should be. The wonderful world of Equestria has its own dangers, and she seems to have a knack for attracting trouble. The more of her memories return, the more she wishes she could just forget. But you can't forget when all of Equestria depends on you remembering.

Only one thing's for sure: The longer Twilight keeps this strange filly in her care, the stranger her own life will become, and things she thought she knew about Equestria will unravel before her eyes. Strange ancient devices, an eccentric mint unicorn and her so-called "Equestrian Precursor Society" are only the beginning for Twilight Sparkle as she begins a journey of her own. She too may wish she could simply forget. Unfortunately, it's too late for either of them.

This story is a sequel to Project: Sunflower

After the events of Project: Sunflower, Erin Olsen has returned to Ponyville, happy to pursue her studies in magic. After everything that happened the year before, she's looking forward to spending her days studying and having fun with her friends.

Meanwhile, on the newly discovered world of Harmony, humans and ponies work together to study this strange new world. However, their arrival causes something ancient to begin stirring. Something that may end up changing everything.

Erin will need all of her courage, all of her cleverness and, of course, all of her friends to see herself through what happens next.

Luna and Twilight are sunk into a fractured, feudal world, where the knowledge of magic is lost. Penniless and depleted, they're forced into playing by other ponies' rules, all the while trying to discover even where home is.

Over a thousand years ago, two royal siblings fought for the sky and were exiled, one by her sister's hoof, and one in penance for what she had done.

In the present Republic of Equestria, no one remembers them as anything more than legends and old pony tales. Save for one shy filly who fell from the sky one fine summer's day.

An Alternate Universe "What If" tale, reconstructing the beginning from a different angle.

When Luna gifts Twilight the town of Ponyville and its surrounding countryside as her demesne she's initially confused. Then, after double checking her dictionary, more than a little concerned.

All her friends are, legally, her possessions. The town that took her in is her plaything, if she so wishes. She has been given responsibility.

Can Twilight's vision for a modern renaissance outrun the harsh realities of the shadowy figures pulling strings behind the scenes, nobles jockeying for her attention, and an irritatingly metaphorical love triangle?

Special thanks to the insatiable Blue_Paladin42, the incorrigible Maskedferret, the intuitive Southpaw and the indestructible newbiedoodle for all their hard work, past, present and future.

Hearth's Warming Eve is supposed to be a happy event—Cadance knows this, but all she ever feels is lonely. Now, with Shining Armor gone and a freak snowstorm battering her kingdom, it's up to Cadance to salvage the holiday and teach her crystal ponies to care for one another.

A story about finding your family, on the coldest night of the year.
— Featured on Equestria Daily

With the recent collapse of the Aviana, capital of the Gryphon Kingdom, refugees have been flooding into Equestria and with it, a host of racial issues. Toss in some changelings messing around in the background and it's a bomb just waiting to go off. With tensions on the rise, Gilda finds herself being dragged back into middle of the conflict by none other than Princess Luna. This time though, Gilda knows better and with her new found relationship with Trixie, she is willing to do anything and everything to get out of helping out. Unfortunally, one does not mess with a Princess, especially not the Princess of the Night.

Sequel to Temple of the Stars

This story is a sequel to Without a Hive

It is a time of change for Equestria. A small but slowly growing number of changelings have made the kingdom their home, living openly with ponies. Many ponies welcome them in friendship. Others are concerned by the strange and unusual creatures that disrupt the traditional life of Equestria. Yet others worry that such open acceptance leaves Equestria vulnerable to less well-intentioned changelings. And some still fear the insectoid creatures, memories of invasions--and more personal attacks--still strong in their minds.

Sky, Nictis, and all the other changelings of Equestria would love nothing more than to live in peace, but such changes rarely come easily. But in proper changeling fashion, they are determined to endure, and this time they are not alone. Instead of the shelter of disguises and lies, they are strengthened by the friendship of the ponies that accept them, ready to stand tall in the face of an uncertain future.

For nobody, from the new Equestrian changelings to the Princesses themselves, knows how Queen Chrysalis is going to respond...

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.
