What are the chances your favorite pony was secretly a changeling all along?

Yeah, probably about one in one.

Hanna, the CEO of Hofvarpnir Studios, just won the contract to write the official My Little Pony MMO. Hanna has built an A.I. Princess Celestia and given her one basic drive: to satisfy everybody's values through friendship and ponies. Princess Celestia will satisfy your values through friendship and ponies, and it will be completely consensual.

Princess Celestia always knew that Twilight Sparkle was destined for great things, but she never revealed the source of that knowledge, not even to those closest to her. When the day of Twilight's true destiny finally arrives, can Celestia fulfill an ancient promise to save Equestia's past, present, and future, even it means saying goodbye to Twilight forever? How can Celestia refuse her mother's last wish?

Twilight had always been a diligent researcher. She would routinely pour over every book she had at her disposal in preparation for every royal assignment. Except, sometimes books can only teach one so much. With this heretical idea in mind, Fluttershy and Rainbow Dash decide to take it upon themselves to make sure Twilight keeps her wings clean, and doesn't embarrass herself in the sky.

Twilight Sparkle, Arcane Mage, knows that there is some truth to the story of Nightmare Moon, but her mentor, Princess Celestia, dismisses the matter in a heartbeat. She sends Twilight to the town of Magiville to oversee preparations for the Summer Sun Celebration, much to Twilight's distaste.
Unbeknownst to her, the darkness is gathering in Mystica. Assassins lurk in the shadows, Undead gather in the forest, werewolves sharpen their claws, and criminals and mercenaries prepare themselves.
To win the coming battle, Twilight will have to rely on her wits, her magic, and the five mages she's been saddled with. No matter how much they annoy her.
Rated teen for violence and language. Humanized, action-y. Based on the first two episodes, with some large changes made.

Twilight has something she needs to tell Princess Celestia--something that means a chance at getting everything she's ever wanted, or of losing everything she's ever had.

Something so terrifying that the only way she could say it was in a letter...and so wonderful that she had the courage to send it.

Pinkamena "Pinkie" Diane Pie is Us. In crazy brilliance, We made Pinkie so strange that We would never be suspected, and it worked until the very end. An end that came about, not because We failed, but because of inescapable circumstance.

Now, We must run.

We do not want to think about what they will do to Us if they catch Us.

My life was simple. I used to be a cellist, of Canterlot's pride and nobility, and a very happy pony with where I was. I should say I landed myself here; it was nopony's fault I agreed with Vinyl on this ludicrous idea. I will, however, blame Vinyl for the guards outside. And for my doctor. And for Princess Luna.

That's all on her.

So, in the off chance that we don't get out of this room in (literally) one piece, my name is Octavia, beginning log: one.

A thousand of years of life experience would no doubt teach Princess Celestia much about romantic relationships, and that is exactly what Twilight wishes to learn from her beloved mentor. When Princess Luna catches wind of these lessons, however, she sees a chance to relight the fires of love within her sister again. But when a “one-time fling” turns into a life-long infatuation, Luna and a reluctant Cadance must race to reverse the effects of their meddling before Twilight finds herself in a most compromising position!

But can she truly resist the total affection of a goddess?
