A Thousand Years Later...

I stared in awe at myself, I had completely transformed. Black slime was sticking to my dark blue coat, my eyes slitting.  I felt my canine's sharpen and my mane turn into a cloud of blue smoke. I turned to Celestia, frightened. My fur was now dyed black, so I retreated in fear.

Dark mist enshrouded me, and I could hear whispers. It told me, "Look at her, she's taken your place as Queen of the night. Just like a thousand years ago, she didn't learn from history... She's the one everypony loves and cares for. They adore her... You? Not so much. She's trying to replace you... It would do little difference if you hadn't returned to Equestria any way..."

"No! I do a lot for Equestria! What am I talking about! SHE does a lot for Equestria, the real pony who owns this darn body." I protested.

"You do, Luna. You should be Empress Of Equestria, not Princess Of The Night. You deserve it, and you would do a better job of Empress than Co-ruler. Look at the sky, it's not even as beautiful. Remind yourself of what you witnessed Luna. Remember... Remember..." The mist surrounded me wherever I looked. I tried to flee, but it dragged me back. The mist flew into my mouth, and infected my soul. I soon recalled every single thing I had seen.

"My beautiful, jewelled sky shall reign... In an immortal night!" All the jealousy Luna... I had once felt, all those memories of the time I was stuck in the moon poured into me. Finally, the mist faded away, and I saw Celestia's worried face.

"My sister...has turned... Into Nightmare moon...again..." Celestia screamed tearfully, watching me smirk.

She turned and galloped as fast as she could, her wings unfolded. She knew just as well as I that there was no way I could return, the elements will banish me to the moon again... The elements of harmony renewed Luna last time after one thousand years.  This time I WAS dark magic, I would be destroyed... There, was no way I could have killed the dark magic that devoured me...

Celestia knew what she was doing, she was going to attempt to use all the magic of harmony in Equestria to banish me... I wasn't going to the moon for another thousand years... I just couldn't. I predicted her moves, and she shot a lightning bolt at me. I made it evaporate the second it was suppose to hit me. She teleported herself away, and I lost her for a moment.

Suddenly, an explosion flared in the corner of my eye, and a crying Celestia used all the harmony of Equestria to banish and abandon her own sister... Me.

Before I could mournfully give a cry in protest, I was locked in the moon...
