A student of Celestia's School for Gifted Unicorns stumbles upon a mysterious house in the streets of Canterlot, only to find it abandoned. Once the door has been opened, it can never truly be shut. Once the house has accepted him, he can never escape it.

His only hope lies hidden in the deepest chambers of Canterlot Palace, in this manuscript.

(A gentle warning: contains psychological horror and mention of but not graphic depiction of sexual activity.)
