Story of the Blanks

Apple Bloom is on her way home after adventuring with her friends when she finds Twilight Sparkle on her way to visit Zecora in the Everfree Forest. Apple Bloom insists on tagging along, much to Twilight's dismay. They deliver the books to Zecora's house safely, but she warns Twilight and Apple Bloom to leave the forest as quickly as possible. As they try to leave, Twilight finds some trees have fallen in their path. While she tries to move them, Apple Bloom spots another filly watching them, and decides to follow her through the forest. She eventually finds herself in a quiet village known as Sunny Town, where none of the residents living there have their cutie marks, despite most of them being adults. After some exploration, she finds an abandoned house hidden behind the town. She makes her way in, only to find the burned skeleton of a filly sitting in the fireplace. As she tries to escape, she discovers the town ruined and covered in overgrowth. Zombies of the ponies she had met stalk her as she runs. It's revealed that a young pony named Ruby had discovered her cutie mark, and the townsponies, believing it to be a curse, murdered her. Ruby's ghost eventually helps Apple Bloom escape, and she and Twilight go home together.
