Behind Celestia's graceful smile and kind eyes, secrets are hidden with a thousand years of practice. The whispered legends of her depravity hide a dark grain of truth, hidden in the mists of time: the clash with Nightmare Moon left her with scars that will never heal.

This was written before Season 4: it's in a Season 3 universe.
An eighth chapter, by Icebox Froggie, is on its way, and will be added to the story at some point.

The 11th Wonder

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.

Now with its own TV Tropes page

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

Lyra Heartstings is a pony with an obsession. Humans, mythical creatures from ancient history. Before now, she was just a theorist, a madmare. But with the discovery of the crystal caves beneath Canterlot, all the clues finally make sense. Now it's up to one pony to brave the depths, the fury of Equestria's finest at her hooves, and find the truth.

Celestia has always watched over her little sister. When she has to banish her sister to the moon, she works to right some wrongs in Equestria so that her sister will be happier upon return.

However, the biggest change Celestia made has gone completely unnoticed by Luna since her return. Celestia calls Luna into her study to bring Luna's attention to one of the biggest changes of Luna's life.

EDIT 3/26/14: In the popular stories box! Thank you all very much! This is my first really popular story, and I couldn't be more grateful for all the positive feedback!
EDIT 3/26/14 (again): Featured! Oh my GOD. This is just too awesome. I'm going to have a celebratory bowl of Lucky Charms and wonder how I came to earn the support of you lovely people.

Princess. The highest and most important title that can be given to a pony in Equestria. Here princesses are the final word in the country's leadership. Their decisions affect the lives of all who live within the borders of the nation. For the past year, the four rulers have gathered in the unassuming town of Ponyville for meetings of the highest secrecy and order.

If the ponies of Equestria knew what really happened behind these doors, they would probably switch to democracy.

The Earth is still reeling from the effects of the Collision Wars against Xenolestia and her hordes of Newfoals, humanity having emerged victorious but a few million citizens fewer. Then yet another Equestria appears, but this time the humans are quick to cut off the head of the snake, capturing the evil Princess Celestia and imprisoning her. But something seems different about this Celestia...something almost friendly.

Can the Harmony and Friendship that Celestia has treasured all her life heal some of the scars left by her wicked counterpart, or do some wounds just run too deep?
