The CMC get an assignment to write a story about anything they want. Scootaloo finds a pencil with funny markings on it and puts it in the clubhouse. The next morning, Saturday, the three decide to write their book. Applebloom forgot the pencil that she was supposed to bring, so they decide to use the weird pencil with the markings on it. When they sign, the three fillies suddenly become extremely tired, and fall asleep on their hooves. When they wake, they find they are in a completely different setting.

(The waking up in another world idea was from a book series called the circle trilogy, the writing the book and going into it came from the series Myst, and the adventuring writing itself down is from a series called the last Dragon chronicles.)

(This takes place between the episodes, "A Canterlot Wedding," and, "The Crystal Empire".)

It is too painful too remember, so Midnight Dust spends his days refusing to recall the death of his love. But when Princess Celestia gives him the chance to go back, will he be able to risk the pain to save her? Will he be able to bear the weight of his own pain?
