The story is set at the end of the nineteenth century, and revolves around the cultural divide between East and West, in this case: Java and the Netherlands. The Dutch colonials are becoming aware that although they are nominal rulers of Java, the island also maintains its own natural order. That order is maintained by "the silent force" (the gonaguna) - a term that refers both to the unfathomable aspects of Eastern culture to Westerners and to a form of sorcery.
