Long ago, when Luna and Celestia were still children, something amazing happened to Luna. It's happened to Celestia already, but Luna never experienced it.

Luna was only a pegasus. Not a unicorn, not an alicorn. Just a pegasus. Celestia was already an alicorn. When Luna's 9th birthday arrived, it didn't turn out as well as it was supposed to. Queen Chrysalis and Luna were good friends before it happened. Luna realized that Chrysalis was plotting to control her homeland, Equestria, and rule the world. Chrysalis injured Celestia very severely, so she couldn't help at all. Luna needed to find a way to stop Chrysalis- and fast. Everything was beginning to fade, it was always night, since only Luna was okay and Celestia's horn broke, so it was very hard for her. And when everything faded, Chrysalis could put on Celestia's crown, and rule every atom of land and water on Earth! But this is very hard for a small pegasus like Luna to do. Can she do it? Will she stop Chrysalis and save Equestria?
