Twilight's curiosity pushes her to go where no bookworm has gone before: on dates. Dates with lots of unfamiliar (and not so unfamiliar) mares. It goes about as well as you'd expect.

A parody of dating websites in general, named after eHarmony.

Princess Celestia is a living legend, but much of her life is shrouded in mystery. Records have long since been lost to the decay of time, and the tale of her triumph over Discord has become a fable. The Princess's memory of the event has long since faded... or has it?

Her faithful student lending an eager ear, Celestia recounts the true story of a war-torn Equestria, the struggle against Discord, and the early years of her own life.

Before she was the Princess of the Sun, she was merely a stranger.

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.

Luna has had enough of Celestia's games, and has found the perfect means of revenge. Using a long-forbidden spell, she transforms her sister into little more than a small filly, all so she could pull the greatest prank ever. Unfortunately, she soon learns that before you fool around with dangerous magic, you really need to read the fine print...

A sequel can be found here.

This story is a sequel to My Little Alicorn

After the events of "My Little Alicorn," everything seemed to be back to normal...except for one pony. Prince Blueblood is now trapped as a colt, his title, possessions and birthright stripped for his crimes. Before Princess Celestia will return him to normal, however, he must prove himself by attending Magic Kindergarten. Even worse, his current situation has attracted the vengeful gaze of two ponies he has offended in the past: the Captain of the Royal Guard and the Moon Princess.

Will Blueblood rise above his past self and emerge a better pony? Or will he sink back into his old depravity, and be stuck a colt for the long term?

Note: This is a sequel to "My Little Alicorn," so you might want to check that out first.

War. War never changes. Two sisters, co-rulers of Equestria, will find that boredom may tear even their shared-kingdom apart.

Many years after sending her beloved protege to Ponyville, unease sits heavily on Princess Celestia's heart as her relationship with Twilight Sparkle seems to have cooled despite all they've accomplished together. On the advice of her sister, Celestia sets out to investigate and resolve the lost connection with her most faithful student. What does it mean to be a Faithful Student...or a Princess of the Sun?

Earned a six-star rating on Equestria Daily and featured on its very own TVTropes page!.

The earth spun through space. Basking in the light of the sun on one side, and of the moon on the other. The eternal dance playing out as it had for untold years. The sun roaring and bright, the moon cold and aloof, while the earth sat in between, bustling with life and growth. Below on the expansive surface of the world, in a country, in a village, in a house by the forest a yellow pegasus walked out the door to check on her animals. She was not particularly brash, nor brave, or all that strong of will. And the day was not of particular importance. Still, on that unimportant day, the unassuming pony would uncover a long held secret.

Comments and stars appreciated.

When a mishap occurs with Celestia's bathroom scale, an ancient protocol that may just doom Equestria is set into motion. With the entire palace staff now conspiring against her, the sun goddess must not only contend mountains of paper work, dancing celery sticks, and steroid pumped stallions, but a sister who will take this chance to torture Celestia any way she can as payback for her banishment. Lock the cupboards and barricade the fridge! It's the Royal Diet!
