The Pauper & the Magician (2016)

Once upon a time, there lived a powerful magician with darkness in his heart. He was the greatest sorcerer in all the land, and he used his abilities for deeds both evil and strange. In a rare moment of weakness and boredom, the magician tossed his magical book to a panhandling pauper, inviting the pauper to be enveloped into the magician's own unique, twisted dimension inside the book itself.
