Twilight Sparkle never seemed to notice Lyra Heartstrings. She didn't even remember Lyra's name.

They were friends back in Canterlot and even went to school together. Yet Twilight didn't notice that Lyra just happened to move to Ponyville the same day she did. She didn't even notice when Lyra appeared at her welcoming party. Nor did she ever seem to spot her old classmate passing by in the background on any other day during her stay in Ponyville. Some days she could look right at Lyra and never realize that they knew each other.

Lyra isn't a very noticeable pony. She has put a lot of effort into that.

Set in late season 5, after Amending Fences.
Note: Lots of spoilers in the comments.

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.

Fancy Pants and his lovely wife Fleur are quite possibly Canterlot's most heroic duet. Together they conquered countless events, faced hordes of snobbish socialites, and emerged victorious from the most dire of faux pas. May their bravery and finesse be forever remembered on parties to come!

There is a missing element in their perfect life, though: the joy of having a child and becoming a family. When conventional methods fail, will the couple muster enough courage to seek out the alternative, or will they stay a duet forever?

Enter Chestnut—a daring filly from beyond Equestria, out of their social stratum, and definitely exceeding their boldest expectations.

For better or worse.

After a run in with a spell gone wrong that involved Twilight Sparkle, vampire fruit bats, a lot of staring, and then resulted in an unfortunate apple massacre, Fluttershy thought her life had returned to normal after Twilight successfully removed the spell’s effects.

That was until she started waking up in the middle of the night with the odd cravings for apples.

What started as just mild attacks of the midnight munchies soon became frequent late night excursions to the Apple family orchards, with only hazy memories and the lingering taste of apples left when Fluttershy awoke to find herself near or sometimes even in the branches of an apple tree.

Unless she can find a way to control the unwelcome urge to gorge herself on the ripe, red fruits, one of her best kept secrets is bound to be discovered.

PaulAsaran was kind enough to do a review for my story.

How would things be different if Twilight had never made it to Ponyville? Twilight Sparkle finds out just how different things could be when she is forced to travel to her own past while chasing down a mystery; a plot to erase Princess Twilight Sparkle from history.

Landing in a time just weeks after the one thousandth Summer Sun Celebration, she finds a world shrouded in an eternal night, where the Elements of Harmony were never recovered. Can she fix the things that should have, but didn't happen? Or is this Equestria destined to head down a different path?

Chinese Translation by Hell Organist

Mort, also known as the Pale Pony (of Death), has been tasked to take time off from his rigorous duties of reaping souls. Seeking guidance, he is directed towards the town of Ponyville, to learn about the magic of friendship from Twilight Sparkle and her friends. All he needs to do is keep his true nature a secret. That shouldn't be too difficult...right?

Special thanks to Specter-Von-Baren and Pyrite Foolsgold for their help in proofreading and editing this story, as I really needed it. Additional thanks to Pilate, Chuckle5, Unimpressive Vagaries and Admiral Biscuit as well! Couldn't have done it without all their help!

For another excellent take on Mort, check out Sip's version!

Lemon Dreams is a happy pony with a perfect life in Ponyville. There's only one problem - she thinks she's a lemon.

Is she really a pony-shaped citrus fruit, or is she just crazy? Does it even matter? When Lemon Dreams finds herself at odds with the ponies of Ponyville and pursued by a strangely familiar ghost, she realises she must discover the answers to those questions before it's too late.

This story is a sequel to Midnight's Radiance

Sunset finally has time alone with Shining Armor. Naturally, she's too distracted to take advantage of that, thanks to what everypony's been saying.
She's the one that saved the princesses. The one that saved Equestria. 'Sunset Shimmer the Hero'.
But Sunset, she just wants to change. She wants to become a better friend, and be closer to the ponies important in her life.
So just how is she supposed to do that, if those very same ponies want her to be the hero everypony believes her to be?

Thanks to Cloureed again for the cover!

Baron Gaberdine has a lot to learn about his new barony. And himself.

Fortunately, he has a very young teacher.

Chrysalis is beaten. Her invasion of Canterlot has failed. Her hive has been scattered to the winds. And with Equestria on guard, love is in short supply. She has failed her people, and now the future looks bleak and grim.

But there’s a change in the air. Chrysalis can feel it in her bones and in her dreams. Something is calling to her, drawing her and the remnants of her hive north. To the place the changelings once called home.
