"My dear Twilight Sparkle,

Thank you for your recent letters. And I must apologize to you first and foremost that I have not responded back in kind to each and every one. I imagine has this concerned you, but please don't worry. Things have been very unsettled here in the castle as of late. Princess Luna has been researching Equestrian history, and I find myself in a strange kind of mood..."

Prequel to The White Mare
Fluttershy has recently taken up residence in her little cottage on the edge of the wild Everfree Forest, and has enjoyed the greater opportunities to go on excursions with her mysterious mentor, the reclusive goddess ponies know as "The White Mare" but whom she knows as simply Celestia.

One day her ancient friend approaches her with an adventure well outside the little pegasus' comfort zone. Will she be brave enough to attend the Great Dragon Migration, and who might they meet when they're there?

Twilight Sparkle wants to reestablish her old rapport with Princess Celestia - the close relationship they had when Twilight was the Princess’s personal student. But life moves ever onward and the connections they had in the past will not be enough for the alicorns to overcome the challenges that lie ahead. To make it through their shared trials and revelations, Twilight and Celestia will need to grow beyond their existing bonds and become much more than faithful student and immortal mentor.

After Twilight returns from the Human World, Celestia is desperate to know of her former student, Sunset Shimmer, and what happened to her. Upon learning of the horrible things her former student has done, Celestia breaks down in tears as Twilight asks why she was so important to Celestia and why she never told anypony. Celestia tells the story of her and Sunset. How they were so close, and how one secret ruined everything between them.

Only a few hours after she learned of the Griffon Empire's invasion, Princess Celestia surrendered herself to the griffon army and asked for an audience with the Griffon Emperor.

The Emperor thinks she's here to negotiate Equestria's surrender.

He's wrong.

A recurring nightmare convinces Luna that, since her return, she has never regained her sister's complete trust. And at the forthcoming Festival of the Eclipse, she decides to make amends with a bold gesture.

But Luna's solution causes consequences she never anticipated. Consequences the whole world will feel. Now, Celestia and Luna must set forth on an adventure that will take them even into Tartarus itself, and set everything right before it's too late.

And if they're lucky, they'll rediscover the trust they once had a thousand years ago.

Twilight Sparkle wasn't a pony who adapted to change easily. Was that the reason that, now that her home had been destroyed, she was having trouble sleeping? Was it the hard, unfamiliar bed? The harsh shadows of the castle walls?
Or was it something deeper? Something darker?
As she wanders through the moonlit streets of Ponyville, Twilight is paid a visit by another troubled soul. Perhaps together they can find some solace in the aftermath.

Ta-dah! No more shipping! Should never have included it in the first place, to be honest.

Luna has fallen back to Equestria. And, to her shock, she is no longer Nightmare Moon. Perhaps this is her second chance at life. Will she find it, wandering aimlessly into the nearby town? What will the new ponies she meets think? Can she truly hide among them, disguised as one of their own? Well, perhaps, with a little help from some new friends, as she leaves behind her crown, to run away from her past that haunts her.

But can you ever truly escape the monster you've become?

Princess Cadance's life is fraught with intrigue, chaos, and diplomacy. She has been trained for it—educated, prepared, and hardened by her Aunt Celestia. However, all the training in the world couldn't prepare her for real life. Things only become crazier with the return of her formerly exiled and insane Aunt Luna, and she finds herself responsible for her newfound aunt amid the mysteries in the seaside town of Queensmouth.

A standalone Winningverse story.
