When Ink is exploring the au's, he stumbles upon a new au where he meets a new friend named Nightmare. The both of them create a close bond, and Nightmare explains how the villagers mistreats him and how they treasure Dream. Ink knew Dream for awhile, but Dream never mentions Nightmare. One day Nightmare had enough of the villagers and ate the apple of negativity and leaves Dreamtale empty. When Ink comes to visit Nightmare, he sees that everyone is disappeared, and so did Nightmare. Not mention Dreams new and unusual behaviour towards Ink.
