Twilight:

I woke up that morning just like any other Saturday. I took my time getting ready, and settled down with a good book. Spike was still asleep, like always. Ponyville was still sleeping, and the sun had only just risen. Things were perfect.

Then spike woke up with a slight little hiccup. A letter had came from Celestia herself. I opened the letter and read out loud.

Dear Twilight sparkle,

I have urgent news. My sister, Astreae, has broken free from her prison. Many years ago, around the time of Discord's rule, my sister turned evil. As you know, this was long before Luna made bad choices, so we both did our best to hide all information of our poor corrupted sister from the public. After all, though it was a tragedy, most of our friends had been killed by Discord. Nopony was left to even know about her in the first place.

Please, come to me at once, and bring your friend, Rainbow Dash. As soon as you two arrive at Canterlot Castle, I will tell you more.Please hurry.

-Celestia

"Spike, I have to go find Rainbow Dash!" I screamed.

"I think I saw her over at Sweet Apple Acres. Hurry Twilight! Equestria needs you!" Spike yelled as I galloped down the stairs on my way to find Rainbow.

I found myself listening to the steady beat of my hooves on the Castle floor as I ran and Rainbow's wings beating faster in faster as we get closer to Celestia. My Breathing got deeper, running got harder but I couldn't slow down 'till I reached the top of the Castle. Finally we found the princess looking out over all of the castle grounds.

"Celestia..... we're...... here." I panted.

"Good. Now come with me." She said calmly as she walked out of the room, stopping at the door to wait for us.

She led us into a room I had never seen before. Ever. Inside were scrolls, each one stacked neatly. They were all sorted into categories, history, legend, Alicorn, Unicorns, Pegasi, Earth Ponies, and more. Celestia led us through the labyrinth of scrolls, and finely to one category, Astreae. That category had just two scrolls. One labeled "Before Her Fall" the other labeled "Betrayal". Celestia reached for the second one, and handed it to Rainbow and myself. We took a breath before opening it. Fear rushed through my body.

"No way!" Rainbow yelled.
