Regret Can Last Forever

As she looked around the cold, empty space that was now her prison, Nightmare Moon became angry, and ranted to nopony in particular about it.

     "This is an outrage!" she yelled. "That sniveling foal of a princess is a traitor!" She paced for hours, and finally calmed down. Luna, seeing through Nightmare Moon's eyes, saw a leathered journal a few feet away. In what must have been an immense effort, she forced Nightmare Moon to pick it up.

     "Foolish foal," Nightmare Moon exclaimed. "How DARE thee try to command I, the empress of darkness??" But she had it in her hoofs, and reluctantly let Luna assume control over their body. Luna's normal appearance was now visible, and she levitated the book in the air. She

flipped to the first page of the book. On it was an inscription.

    Dear Luna,

          This is for thee to write thou many adventures in! I hope that most of those adventures are certainly non-dangerous. I hope that you like this gift, and will cherish it always.

     Thou Loving Sister,

  Tia

As Luna found herself tearing up, she noticed that at the bottom there was a hastily written note.

Luna,

If thee find this journal, I just wanted to say that I am sorry for what has happened. I have written this in haste as I recover from, well, an accident. I was hoping to give this to thee on thou birthday, but I give it to you now as a last remnant from me for thee to remember me by.

Love Always,

Tia

     Luna was crying, and closed the book as to not ruin the pages. "Oh Luna," she sighed. "What have you done?"

Day 1, Year 1

I have a done a bad deed. A very bad deed. So bad that maybe even my elder sister Tia may not forgive me. I have rebelled against my kingdom, threatening my subjects and even my sister. Tia saved Equestria by banishing me on the moon, and I am not angry or holding a grudge. It was a good decision considering what i did. I only wonder if my people and most importantly my sister will forgive me and accept my apology.

But maybe that's too much to hope for...

Luna

As she closed the book, Luna looked out towards the earth, she saw a shooting star. As she followed it with her eyes, she whispered, "May nightmares no longer plague thy mind for a thousand years, dear sister."

     In the royal palace, Princess Celestia awoke suddenly. Gasping, she looked around her dark room and realized that the nightmare of re-living the night before had only been a nightmare. Yet why had she awoken so suddenly?

     She climbed out of bed, and gazed out of the window at the moon. She noticed a shooting star speed by, and said, "I wish that Luna is safe on the moon, and will still be the happy little Luna I used to know when she returns.
