Twilight Sparkle was 읽기 a book in her library. Spike was doing some chores and then he spit out the letter. He handed it to Twilight and she read the the note. ''Oh no!'' she gasped. Twilight ran out to the door to find her friends.

''We came as soon as I got your letter!'' Twilight Sparkle said. ''Thanks you, girls. I have wanted to tell 당신 a story...'' Celestia said. ''Long 이전 when Princess Luna and I were in the Castle, we were 글쓰기 letters to ponies. Princess Luna had deep thoughts in her mind. She thought why she couldn't rule Equestria and why she couldn't have powerful strength. She was a bit mad at me that day. After a hard 일 of work, we rested. The 다음 day, I woke up to go outside. Then I saw Luna destroying the castle. At that moment she started transforming into Nightmare Moon. She stood up to me and hit me with her powerful magic. I fell to the ground. I had no choice but to fight back. It was a fierce battle and then it finally ended. I used the elements of harmony. I have sent her to the moon.'' Princess Celestia finished.

''How can she be returning?'' Twilight Sparkle asked. ''That is a good 질문 and there is no answer to it,'' Celestia said.''I want to tell 당신 all one thing. When Princess Luna arrives, be ready and prepare for the worst.''.
