It's been a long day, and The Great and Powerful Trixie decides to spend the rest of the day with her good friend Starlight Glimmer. Unfortunately when she goes to the Castle of Friendship, she cannot find Starlight at all, so goes looking for her in the winding halls. After some searching, she finds a dark room in one of the halls of the castle, and decides to investigate, leading to some rather unfortunate consequences.
