Teardrops

Celestia's kingdom grew. New towns and city's were created, the population expanded and more and more forgot about Luna. Nightmare moon was who Celestia defeated, Nightmare moon tried to bring eternal night. They only knew about Nightmare moon, not Luna. The poor princess that had let jealousy take over and trap her in something she didn't want to be. Nightmare moon was also said to give them Nightmares. Soon Nightmare night was created, everypony fearing her more than ever now. Celestia had flat declined the request at first and Nightmare night wasn't celebrated. It would ruin Luna but since it looked like ponies were going to have fun and not scandalise her sister, she eventually let it pass. Ponies began to know Nightmare moon, not from the summer sun celebration but from Nightmare night now. Celestia was visiting Luna's flower less and less now, until she could no longer. The deep sadness made her feel cold and would send her into a depression for a couple of hours. It was just such a torment. Nopony had been alive long enough to know what kind of torment she was going through. Because nopony knew that Luna even existed, nopony knew princess Celestia even had a sister. All they knew, was Nightmare moon.

Luna's flower began to wilt.
