After the defeat of Tirek, Equestria is safe once more, but Luna can sense that her sister is troubled. When Celestia retreats to the starry realm of ascension in order to look upon the past, Luna joins her to discover what is bothering her.

The youth of Celestia and Luna was a very long time ago, you would never have guessed that they grew up with Discord!
But sadly Celestia did something that ruined their friendship, and turned Discord into the Chaos causing monster he is today!

My first fanfiction, please tell me how it is :)

Celestia goes to extra effort to make the sunrise perfect for a very special holiday. Yet once that is done, Celestia herself is left sad and alone, for she has never been a mother... (A short Mother's Day story.)

Momlestia is Bestia. At least for today.

Equestria is safe once again, and Twilight has found her destiny. Still, the beginning of this new chapter in her life comes at a high cost, and Twilight must come to terms with the bittersweet ending to her latest adventure.

Twilight Sparkle comes across a small, battered diary detailing a new form of transportation. While the research is sloppy and the notes incomplete, Twilight takes it upon herself to see that the ancient project is completed.

Of course, nopony said it would be easy.

Twilight and Celestia have been in a relationship for a while now, and Twilight decided that it was the right time to introduce her new marefriend to her parents. Celestia was nervous, of course, but thought little of it.

But when Twilight asks about Celestia's parents, things get far more complicated.

After all, it's always a little awkward when your parents aren't exactly ponies in the first place.

And in Russian!

Super special thanks to Fuzzyfurvert and Habanc for putting up with me and my silly ideas and generally being awesome, and to OnionPie and Craine for proofing.

In this alternate take on the ending to Season 2, Chrysalis actually triumphs, defeating everypony and turning Princess Celestia into a Changeling. However, almost immediately, Chrysalis's plans begin to go awry. For Changelings feed on love. And who is more beloved in Equestria than Princess Celestia?

Luna receives a message from a mysterious stallion to meet him at her old castle.

The meeting doesn't go as expected.

Following her defeat and expulsion from Canterlot, Chrysalis is fuming. That mood doesn't improve when Celestia arrives on her doorstep. Things degrade from there...

Thanks to Famosity from Deviant Art for letting me use her art for the cover.

This isn't where I belong. I left all this behind years ago, moved on with my life. But a mare from my past brought me back, and now she won't let me go. So I'm stuck here, trying to make the best of it with ponies that don't understand me, don't even like me. But when something moves in the darkness, and when things go wrong in the cold, dead night, they'll turn to me to try to set things right.

Why? Because once a police pony, always a police pony.
