From publisher blurb: Spider Kingdoms is a splatbook for the Yin Yang Panda role-playing game. It contains basic information about the eponymous Spider Kingdoms—a vast rainforest bordering on the Dragonfly Empire. Inside you will find basic information about the Kingdoms, it's landscape, culture, and relationship with the Dragonfly Empire, and of course a bunch of new schools (elephant, dolphin, rhino, and crocodile to be exact). And some random tables to inspire you and spice things up.
