Rogue

Celestia couldn't believe it. She didn't want to believe it.

Luna hadn't changed.

Celestia swallowed her saliva as she looked at her younger sister, she looked like the same beautiful mare. A gorgeous mane that flowed so wonderfully, with the stars of the night imprinted on; a beautiful smile that was held with fun and laughter; honest blue eyes that looked so truthful that you could believe her every single time, even after all the bad things. She looked so regal, graceful, elegant. As if she was a new pony after Nightmare Moon.

But Luna hadn't changed at all.

The Nightmare Forces were still lingering inside of her; holding back Luna's hate, her jealousy, her anger toward Celestia. The older sister looked down to the floor, not wanting to look at pretty Luna's face, not wanting to believe that the younger had still felt that way towards her.

"Luna, I love you." Celestia whispered, tears streaming, murmuring the same words, over and over and over again, not wanting to stop until her sister loved her too. Celestia thought that they had gone past the conflict, that what happened before was over, done with. But apparently not.

Celestia heard it, the movement of a hoofstep, the short breath of a princess before she spoke. The older princess cringed, not wanting to hear her younger sisters words, but hear them at the same time, "Sister," Luna had said, in her royal voice, but very softly spoken, "I wish for you to leave. If I ever see you again," she threatened, "I will call the Elements of Harmony against you." Luna said and finalized.

Celestia opened her mouth to protest. In front of all her little ponies, in front of all the ones she held dear to her heart, in front of the Elements of Harmony, in front of Cadence and Shining Armor, in front of everypony that she had known, and everypony that she hadn't known, she was being exiled from Ponyville, because of a mistake she didn't do.

After all this time, how did no one defend her? Surely, someone must have been kind enough to go against the exilation? Not even her little student, Twilight Sparkle, who she raised and even made meet her friends? Celestia sobbed as she looked at the eyes of the judging ponies, watching her in the most damned situation in her life. This very situation that even surpassed Luna's banishment. Luna's beytrayal.

Celestia looked up, her eyes filled to the brim with sorrow and tears, "Goodbye, Luna; everypony, my little ponies." she said as she looked to everyone in the eye, "You have all disappointed me. As in the future, you will see it was not I, who has made the mistake, but every single one of you." she looked back to Luna, her dearest sister, "Goodbye, again." Celestia whispered, backing a hoof.

Aside from the coldness in Luna's eyes when Celestia saw her, the older mare thought that she saw the tilt of a smile, in the corner of Luna's mouth. She planned it all along.

Celestia sobbed even more as she turned around. Not wanting to continue her walk of shame, she looked down to the ground, whispering one last time, "Goodbye, my little ponies." she said. "I love you, all of you."

Using her horn, effortlessly, the alicorn teleported, to the edges of Equestria, where nopony dared to roam. She was not a princess anymore, she was a rogue; a different pony entirely.
Rogue Celestia.

The princess looked up the sky of the night, remembering her sister but pushing it to the back of her head, and smiling happily. She rather liked the name.
