The Imperium seeks to explore and chart more of Sirius as a top priority, accomplished through its Frumentarii. Next comes further investigation of the inhabitants of Sirius and their societies, histories, technology, and political situations. Afterwards, technology will be obtained for reverse-engineering, be it through diplomacy, or more subversive methods. Finally, basic diplomatic relations will be established with possible allies or client states near Inverness.
Phase II: Commercium et Culturae
When there are capable ships, the Princeps Numerarius will open up trade relations with various factions in order to bolster the Fillii economy, strengthen diplomatic ties, and continue exchanging technology. A side effect of this is spreading good Fillii culture to the unwashed barbarians of Sirius, showing them the way of civilized peoples. In time, this will help to prove the legitimacy of the Imperium as a regional player.
Phase III: Potentia et Incrementum
After having established itself as a regional entity, the Imperium looks to expand beyond the jumphole of Sicilia, and start holding territory in Sirius. Inverness is first on the list, with the local space stations coming under Fillii control through either peaceful or violent means. Alternatively, the Imperium would look favorably upon the construction of their own station in the region, provided it is properly taken care of with necessary facilities. When Inverness is secured, the Imperium will sign treaties with other factions to gain political support in its endeavours. Local territory which is weak enough to be exploited may be conquered and added to the Imperium, or converted into client states.
Phase IV: Divide et Impera
Once the Imperium has gained enough resources to become a regional power and have a powerful standing military, it will begin large-scale military conquest of any who refuse to be converted into client states. Mass executions and intimidation tactics will be used to keep the immediate post-conquest population in line, and conversion of local culture will begin immediately. Protection against external and internal threats will be provided en masse when available. Martial law will be imposed upon the populace in all conquered territories until order has been restored and the population begins to accept Fillii culture.
Phase V: Pax Filliana
After the mighty Fillii war machine has conquered all in its way and the Sirian populace has successfully adopted the single, monolithic cultural identity of the Fillii, the ultimate goal set by the gods will have been achieved. The legions will put down their war drums, and be converted into a domestic force for good that protects the well-being of its citizens, and the power of its dictator.
