This story is a sequel to Princess Twilight Sparkle's 500th Birthday

Five years have passed since the events of that fateful morning. Smarty Pants and her friends set off on an adventure of a lifetime to discover the secrets of the past when they awaken a… oh wait, that would be spoiling it!

Many questions from the first story will be answered! New questions will arise. Lunch will be had, pies will be thrown, blood will be kept inside bodies because seriously, ew blood, you guys.

Notes:
- Cover art commissioned by HAK2. Check out his other stuff, too.
- This is a story in the Birthdayverse.
- This story was written and completed (except for the epilogue) before Season 4 of MLP:FiM aired.
- Many thanks to my faithful Pre-Reader and all around super-duper best pony, Blood Lord go read his story, too!

This story is a sequel to The Chaotic Touch of Harmony

It has been nearly a year since ponies and Mions appeared on Earth with humanity being divided in how to deal with both. While the ponies in the newly formed town of Trinity work to establish themselves, the rest are scattered throughout the planet while trying to find their place in the world and the Cult of the Koridost is quietly ramping up their genocidal campaign against humanity.

Will Discord’s vision of humanity’s ruin come to pass? Or will his less than direct intervention allow the planet to see a brighter tomorrow?

It is highly recommended to read the first arc because this is a direct sequel and many plot elements may be confusing without previously established context.

Again, thanks go out to Quite Quiet for his editing work.

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.

Humans.

Truth or myth? Ancient lost civilization or just an old pony's tale?

No pony has ever seen one, and most haven't even heard of them. But Lyra knows that these wonderful creatures are more than just old legends, and she's going to find out... and possibly drive her roommate insane in the process.

"My name is Lyra Heartstrings, and you will not remember me. You won't even remember this conversation. Just like with everypony else I've ever met, everything I do or say will be forgotten. Every letter I've written will appear blank; every piece of evidence I've left behind will end up missing. I'm stuck here in Ponyville because of the same curse that has made me so forgettable. Still, that doesn't stop me from doing the one thing that I love: making music. If my melodies find their way into your heart, then there is still hope for me. If I can't prove that I exist, I can at least prove that my love for each and every one of you exists. Please, listen to my story, my symphony, for it is me."

A changeling who finds responsibility thrust upon her after the failed Canterlot invasion.

A unicorn who finds herself part of first contact with a strange new creature.

A princess who finds hints of one she long since lost in another's mind.

With the arrival of a strange bipedal creature into Equestria, all three will find themselves intertwined with the fate of the girl. When language cannot be understood how will communication with the new arrival be achieved, and what secrets may the creature be bringing with her? What does the girl possess that may alter how the changeling in particular sees the world.

What could the girl possibly have that would allow one word – hope – to resonate so strongly, not only for herself but also the changeling.

This is a retelling of A Voice Among the Strangers from three viewpoints in particular. You don't have to read AVAtS to read this one, as I will be attempting to make each a full story on their own.

Also, this seems to share a Tv Tropes page with A Voice Among the Strangers!

(Thanks again to Tulip for the Cover image!)

Jessica finds herself flung into a world she has little concept of. Everything is strange and new to her, but worst of all she cannot communicate with the native inhabitants. A world of monsters and sapient ponies, griffons and other assorted beasts is no place for a human girl.

How will Jessica cope? Without an understanding of their language how will she make her way in the world, will she even be able to ever communicate with them? Why was she even brought into the world and is there even a way for her to get home?

(Thanks to Tulip for the Cover image!)

(Also now apparently has a Tv Tropes page in the making. )

Now has a re-telling in progress focusing on the Equestrians' side of things, A Stranger Among the Voices

It had to happen eventually.
...actually, no. No, it really didn't.
Set immediately after the events of Boast Busters, Trixie finds herself in a quandary when she realises that she has left her purse behind in Ponyville. She faces a humiliating walk back into town to pick up her money.
Before she can turn back, however, she meets a magical, sentient pine cone... sigh. Okay. Here's a proposition.
If you can make it to the end of this story without going "what" even once, you win a free internet.

Distance can drive us apart. It can also bring us closer together.

After all is said and done, and the ponies have gone their separate ways, the only way they have to keep in touch is through letters.
