Are pegasus wings really fragile? Do unicorn spells really fail catastrophically? And just how explosive is chocolate milk, anyways? Join Applejack, Rainbow Dash and the rest of the MLP crew as they not only tell the myths, but put them to the test!

Thanks Pustulioooooo for his WONDERFUL Coverart!

This story is a sequel to Princess Celestia The Changeling Queen: Stories Behind the Mask

At the Royal Wedding, Chrysalis and the Changelings were revealed to all of Equestria.

But another mask was torn away that day. A mask born for a thousand years. A mask created on one promise. A mask, that has become synonymous, fused, to its bearer.

A mask that when ripped off, causes Twilight, her friends and Luna to question everything they ever knew about the one pony, one very important pony.

At the Royal Wedding, the meaning of the phrase 'Princess Celestia' changes forever.

NOTE: Chrysalis is NOT Celestia!!! That'd be impossible to pull off.

We all know the story of how the Princess’ young student and five friends defeated Nightmare Moon and brought Princess Luna back to our lands. But what if the tale were false? What if the young Twilight Sparkle on the event of her entrance exam had not been rescued by Princess Celestia, but instead lost her mind among the power of her youthful surge and had to be sent away, far away before she could destroy all of Canterlot with her newfound power. Now the feral unicorn prowling the Everfree Forest only vaguely remembers her past, slipping away from constant terrifying attempts to capture her.

And she is beginning to remember what true power felt like.

It is the year 2038, and the Earth is slowly being consumed by a space-borne monstrosity dubbed the Black Tide, which is using nanotechnology to remake the planet into something hideously alien.

Erin Olsen works for Project Harmonics, humanity's last-ditch effort to find a new world before the Tide can wipe them out. But when that world is found, and it turns out to be occupied, Erin will need to find the courage to face the unknown in order to save the inhabitants of both worlds.

There is now a follow-up to this story: Sunflower - Side Projects
Sequel: Project Sunflower: Harmony

This is the story of the end. This is the story of the death of Equestria. It is the story of the reign of her royal majesty, Princess Twilight Sparkle of the Fading Sun.

The alicorn sisters are dead and Equestria has turned to Twilight Sparkle to guide it. However, just maintaining a dim sun a fraction as bright as her mentor's keeps the new princess near her limits.

Years have passed and Twilight Sparkle is sure of only one thing. Equestria is dying.

NOTE: Written before "It's about Time" in season 2. Everything after "Read it and Weep" was ignored throughout this story.

Canterlot... For centuries, Canterlot was the shining gem of Equestria, the pinnacle of pony society. Now, it’s a reminder, a bleak and monolithic warning to the world. 

Changed by the chemical and technological poisons that plague the mountain, an abomination of nature, I wander the greatest disaster Equestria has ever seen. 

... I will escape eventually, and when I do, I hope my friends still see me as Twilight Sparkle, and not the monster that hides among the ruins. 

Mood Wings - Observations on Pegasus Body Language.

When Twilight Sparkle finds this book, she discovers an entirely new field of research. The secrets of pegasus wings lie before her, and she insists on making her own observations on the matter.

How?

Field research, of course.

Everypony has one 'Longest Night', a night that just never seems to end, whether they want it to end or not. For Celestia, her Longest Night began on the first night she had to raise her sister's moon.

Heartbroken and filled with despair that she may never see her sister again, Celestia makes a wish upon a falling star to see her sister one more time. Little did she realise that the stars listen.

A one-shot story of two sisters, and one Faithful Student.

In a world full of magic, mere words can pose a deadly threat. When simply reading a sign can instantly infect the unwary, and cases start to turn up all around Ponyville, Twilight Sparkle casts the only spell she can find that can give her the time she needs to find the cause of the plague. But then she has to figure out how to stop the epidemic... without being able to read.
