While the Imperia would prefer to be the only organization available, others in the empire have differing opinions. The Mariner races established their own federation not only for trade but for solidarity with other non-Imperian peoples. The Sicarii, a collection of Renanim tired of being exterminated, perform acts of resistance and terrorism against the Imperia. The different cults of Marinasta act as their own entities and on some planets possess the power of nations.
