The mane 7 were having a fun summer vacation in the beach. Sunset Shimmer was happy that she had come so far. She was admiring the view, until she saw something shiny from afar and decided to see what it was. She stops on her tracks when she had finally found what she was looking for and picks it up to see it was just a mirror, she examines it and saw a cracked lapis lazuli gem behind the mirror. Sunset decided to keep it because it was rare for her to see, what she didn't know, is that someone is trapped and needed to be free.
