Regret Can Last Forever

Once upon a time, in a magical land called Equestria, there were two regal alicorn sisters who ruled over the land. The elder was named Celestia, and was responsible for raising the sun. The younger, Luna, was responsible for the stars and moon. It was also her duty to come into ponies' dreams, and help them rid of their nightmares.

     And so the sisters retained harmony in their kingdom filled with special and friendly ponies. But Luna became envious and angry with her sister, who was praised and worshipped in the day. Luna herself was lonely and friendless during the night, for that was when ponies rested and shunned her beautiful night. She became more distant and depressed as days past by without seeing anypony stargazing at night.

     Celestia noticed her sister's unhappiness and tried to comfort and reason with Luna. But bitterness in Luna's heart had taken over, and she dashed out of the room. As she tried to fly away from the palace, an evil smoke engulfed her. It was miasma, which corrupts the pony it attaches itself to. Luna's screams filled the night as she tried to escape from the miasma.

     Celestia galloped over to Luna to save her, but she was too late. In her sister's place was a taller, darker, and eviler alicorn. This was Nightmare Moon! She vowed that darkness would shroud all of Equestria, and demanded that Celestia bow down to her.

     As Nightmare Moon manically laughed, Celestia attacked her, and the battle waged on for many hours. But Celestia had lost, and Nightmare Moon walked into the palace to start "redecorating" it to her liking. She did not know that Celestia had weakly flown off to gather the Elements of Harmony to defeat her once and for all.

     As the elements created a rainbow towards Nightmare Moon, she screamed, "This is not the last thou hast seen of me! The night shall live on!!!" The rainbow had engulfed her, and Celestia started aiming her to the moon.

     Suddenly, she heard, "Tia..... Tia......" Gasping, she looked up. She could make out her sister Luna, her face full of pain. "Tia..." she weakly said. "Why are you hurting me Tia?" With that, Celestia pushed her to the moon, and light had returned to Equestria.

     As her subjects cheered her on and readied for a feast, Celestia never once realized how hard she'd been sobbing.
