Across the ocean stands the great land of Zhongguo, where Dragons and Phoenixes live among Cats, Rats, Dogs, and dozens of other races; Where the Celestial Bureaucracy governs not only the Noble Houses of Earth, but also the Heaven Court and even the weather itself ... Where evil lurks in forgotten places, and ambition stirs in the hearts of the greedy and the wrathful ... Where masters of the mystic martial arts make impossible feats look effortless ... Where wizards conjure forth balls of fire, bolts of lightning, thunderstorms, or even changes to fate itself ... Where adventure can be found from the uncharted wilderness, to the Forbidden City of Majing, and all places in between.

THE BOOK OF JADE is a supplement to IRONCLAW: SQUARING THE CIRCLE, describing fantastic new locations for adventure, and new character creation options, such as new species, new career, new martial arts, and new magic.
