The phyles coexist much like historical nation-states under a system of justice and mutual protection, known as the Common Economic Protocol (CEP). The rules of the CEP are intended to provide for the co-existence of, and peaceful economic activity between, phyles with potentially very different values. The CEP is concerned particularly with upholding rights to personal property, being shown to provide particularly harsh punishment for harming the economic capability of another person. The role of the CEP in the world of the novel could be seen in comparison with the roles of real-life international organizations such as the United Nations and the International Monetary Fund.
