Piaoshine

Above a bottomless sea of clouds, the clans on the floating islands of Piaoshine obey the sacred law of the murim, or martial arts. No one in the great families of the twelve clans is above the rules, which are enforced by the divine sect, keepers of harmony. The most important rule that no martial art master must ever transgress is the interdiction to mingle with the blazing might of the Sun, the pervasive power of the moon, or the demonic cult that adores the demons from below the clouds.
