"And, now, your two princesses, Princess Celestia and Luna!" Silver Suit, the royal adviser, announced. The crowd cheered.
The two sisters stepped up on the platform. Celestia looked at Luna, just to see her expression. She looked happy, happier than Celestia had seen her in a long, long time. But yet, her smile was laced with sadness. Sadness that one could not forget. The pain of living for centuries, and knowing that your sister could not save you.
Perhaps Luna could never forgive her.
What had happened a few nights ago, nopony ever truly knew. After Nightmare Moon and Solar Flare clashed, the nightmares seemed to... disappear. Celestia and Luna woke up, rubble surrounding them. Then they flew towards each other and embraced their sister.

The days went on, the more that passed, the more ponies would forget. Which wasn't necessarily a bad thing. The fact that my subjects admire my duty raising the moon comforts me.
I wish I could forget. Forget the sorrows, the troubles. Forget the pain that I have caused. Forget all I have done.
Forget the nightmares that still plague me.
But, for now, my troubles can wait. After all, my sister awaits.
