The Jewel of Xuan Wu is an ancient and archaic object of mystical power and magical properties. It holds a small fraction of the total power of Xuan Wu, the god of all martial arts and teachings of fighting, and was created after Xuan Wu crystallized his powers and left them behind to be scattered into select beings throughout history in the BTUverse, thereby inheriting small portions of his power and knowledge in the form of fragments. The Jewel of Xuan Wu can only be assembled when all the fragments of Xuan Wu are brought together and pieced back as one object, resulting in the extremely powerful arcane object which can grant untold powers to a user.
