Mighty Lung Wa once controlled much of Tian Xia, but the empire crumbled a century ago. Three Successor States have squabbled for dominance ever since, each insisting that it alone is the rightful inheritor of Lung Wa's glory. In the shadow of these mighty nations, the humble land of Shokuro has sought the means to discourage its neighbors' territorial ambitions and earn their respect. When a retired hero learns of a lost, legendary palace that might protect relics of the old empire, she calls on the Pathfinder Society for assistance finding the fabled site. The PCs must travel to each of the Successor States in search of clues to uncover the palace and the treasures within.
