History is changed forever when Venetian trader Marco Polo embarks on an epic journey through hostile tribes and treacherous terrains to the fabled court of Kublia Khan, the legendary leader of the Mongol Empire. Together with his faithful servant Pedro, Marco spends the next twenty years of his life experiencing the astonishing thrills, pleasures, and excitement of a world few Europeans had ever seen.

The Time Warp Trio find themselves in a desert in China, and in order to retrieve their magical book from the court of Kublai Khan, they must pose as astrologers and join the caravan of Marco Polo and his father.

Cousins Patrick and Beth travel in Mr. Whittaker's invention, the Imagination Station, to thirteenth-century China, where they meet Marco Polo and Kublai Khan and are mistaken for Christian shamans.
