Set shortly after the Nightmare Rarity arc in the comics.
Nightmare moon believes Twilight is responsible for both of her defeats and has decided to take care of the root of the problem. With the last of her strength she enters Twilight's dreams to claim her revenge.

30 years after Twilight's ascension she has taken a student. On this day she decided to tell her student about the story of Nightmare Moon. Twilight expected Shooting Star to just accept everything she was told. She didn't. Now Twilight is making the ultimate decision. She's going to tell Shooting Star the real story of Nightmare Moon.

Love to my editors Selbi and Don't Look at My Name Bro!!!

Equestria's history is like a swan on a lake, seemingly graceful motion hiding the furious effort beneath the surface. Whose effort? Twilight is about to find out.

There's a lot of unpleasant surprises that can be found in photo albums. A third pony in what you thought was a private moment, inexpertly applied bodypaint, or just evidence of that time that your mother dressed you up like a burrito.

Twilight Sparkle was expecting to come out of Family Night with a few fresh blushes on her cheeks. What she wasn't expecting was a mysterious pair of wings in her baby pictures.

Hopefully Celestia will have some answers.

Many thanks to Present Perfect for supplying the brilliant concept, and to Evehly for the beautiful artwork.

Twilight looks deeper into a certain prophecy, and finds an answer much stranger than she expected.

What are these mysterious 'stars'? Who wrote the prophecy? And why the heck does everything seem to run in cycles of a thousand years, anyway?

One-shot.

History is a vague thing. It is written by those who are left behind to tell the tale. Who can tell truth from fiction if any chance for a viable reference is far beyond reach?

What knowledge is altered? What is lost? What is hidden away?

And for what purpose?

Knowledge can be a powerful yet dangerous tool. Especially dangerous for those that rely on knowledge alone.

This is my first try on writing. Any feedback is welcome!

I will add more character tags as the story progresses. Don't want to spoil the fun after all.

A week ago, love was in bloom. Cadance, the Princess of Love and Shining Armor, Captain of the Royal Guard defeated and banished an invading army with the power of their love alone.

So why can't their sister start a conversation with her marefriend? They're already dating, for pony's sake! Maybe they just don't know each other well enough yet...

I just put the two together

It has been a long day for Twilight Sparkle. Now, with the Friendship Games over, she returns home with Cadence to her family. But how will they react when she tells them what happened?

This story is completely canon based on my own opinion. I do not own MLP or any related characters.
