- Rhea (108,000 pop)
- Mimas (5,500 pop)
- Composed of about 75% water ice and 25% rock.
- Ninth largest moon in the solar system; second largest after Titan in the Saturn system.
- Possesses a sludgy, partially melted subterranean ocean, but not enough of one to have warranted colonization at the required depths.
- Rhea has a set of very thin, almost imperceptible rings.
- Initial colonization of the Saturn system began with settlement of Saturn's largest moon, Titan by a diverse combination of metanational and national interests from the predecessor nations of the Southern Bloc and the Oceanic League, most notably Pacifica, Japan and India. With its vast ammonia and methane reserves, Titan represented - and still does - a key source for the hydrocarbons that still to this day dominates the powered spaceflight economy.
- As economic exploitation of Titan expanded, it was decided to relocate both naval shipyard and security operations to nearby Rhea in an effort to ensure security functions, as the commercial enterprises on Titan were so disparate and so uncontrolled as to make the central governing body's hold tenuous at best. The Rhean Divisional Authority thus formulated turned Rhea - and later Mimas as well - into a giant military base. The naval shipyards in orbit were initially mostly used for repair, refueling and retrofitting, but eventually began to construct ships of their own. Today, Rhean shipyards are capable of constructing destroyer-class vessels, and in 2470 completed a pilot project to construct a prototype Dreadnought-class battleship.
- After the fractious governing of Titan became impossible under the existing system, the Republic of Titan was organized, though the finished product was only dubiously more effective than its pre-republic state. Amidst considerable public outcry, pre-republic Titanite authorities exempted the Rhean Divisional Authority from republican sovereignty, as neither the pre-republic Titanite authorities nor the military governor of the Rhean Divisional Authority trusted what they feared could become mob rule in the new Republic of Titan.
- In the ensuing decades, the Republic of Titan and the Rhean Divisional Authority continued to maintain extremely tight military and commercial ties with considerable interchange of officers. Factions in both governments maintain some distrust of the other, however, with the Republic of Titan constructing its own military forces to "supplement coalition naval forces" on the one side, and the Rhean Divisional Authority consistently denying Titanian corporate access to Rhea's ice-water, something that has forced the Republic of Titan to deal much more aggressively with the Iapetus Coalition's water-miners than it would otherwise have.
- Until the territorial encroachments of the Alliance, the Titan-Rhean Coalition was steadily pressuring the ancillary polities of the Saturn system to accede to Titan-Rhean hegemony, if not outright annexation, but the arrival of the Alliance juggernaut has upended that trajectory. Although the Rhean Divisional Authority's navy is significant, it is still not large enough to safely go on the offensive against the Alliance.
- Water Ice
- Expansive naval shipyards capable of up to Dreadnought-class battleship construction, although the majority of its capacity is devoted to Destroyer-class and smaller ships.
- While an extremely close ally with the Republic of Titan, internal tensions do exist over issues of lack of Titanite cooperatives' access to Rhean Divisional Authority possessions and a general attitude of contempt on the part of the Divisional Authority that the Republic of Titan is incapable of standing militarily on its own without the Divisional Authority's assistance.
- The Alliance is the single main threat to both the Republic of Titan and the Rhean Divisional Authority. Massive naval construction has begun, but the reality is that the Titan-Rhean Coaition is desperately out-gunned, and it is only the inherently exceedingly cautious advance of the Alliance that has kept the situation from breaking out into full-fledged war.
- As an authoritarian military dictatorship, the Rhean Divisional Authority is seen unfavorably by the more democratic polities:
- The Oceanic League
- The Commonwealth of Callisto
- The Democratic Republic of Triton
- The Collaborated Union of the Hildas Triangle
- Due to their failure to extend even limited rights to A.I., the Collaborated Union of the Hildas Triangle is particularly hostile to the Rhean Divisional Authority. As their actual practical contacts are limited, this hostility remains in the realm of repeated political denunciations of the Rhean regime.
Politics and Culture:
- The Rhean Divisional Authority began as the security arm of the Titan Settlement Project, and by the time it became ossified into a de facto authoritarian military state its culture evolved to support a military ethos.
- While there are civilians ("Unclassifieds") on Rhea and Mimas, virtually everyone involved in any commercial or military activity have a rank and a security clearance. In much the same way as the militaries of some polities in the 21st century owned businesses outright, so too does the Divisional Authority authorize, regulate, and profit from commercial activity within its territory.
- A distinctly military cultural ethos has developed on Rhea and Mimas whereby self-discipline, loyalty, focus, and bravery are the qualities that all are expected to aspire to.
- Rheans are pragmatic and realists. To a Rhean, what is right is what works, and if that causes damage to other considerations, then those other considerations will just have to deal. The concept of double-think is prevalent and profound within the borders of the Rhean Divisional Authority, and the Divisional Authority itself maintains a powerful public relations arm known as the Bureau of Morale.
- Unlike Titan where Japanese is the dominant language with English as a minority, but still common secondary language, English is the official language of the Rhean Divisional Authority.
- The actual governance of the Divisional Authority is split between seven competing "bureaus", each of which competes with the others for resources and political influence:
- Bureau of the Army
- Bureau of the Navy
- Bureau of Military Intelligence
- Bureau of Operational Services
- Bureau of Health Services
- Bureau of Morale
- Bureau of Integration Services (education, training, and recruitment)
- While the Rhean Divisional Authority makes expansive use of drones and A.I.-piloted destroyers, it does not extend to A.I.'s even the limited rights commonly afforded those entities elsewhere in the solar system.
- Diplomatically, the Rhean Divisional Authority tends to defer to the Republic of Titan, in return taking the leading role in military measures. This arrangement has become somewhat strained in light of the encroachment by the Alliance, since thus far the Alliance's depredations have focused on Titanite interests much more than Rhean interests, so the Divisional Authority has felt less urgency to address the situation. Moreover, the Rheans often feel as if the Republic of Titan does not respect their role as much as it should, and feel that the Titanians are not pulling their weight in the partnership.
- Despite these frictions, the Titan-Rhean Coalition is unlikely to unravel anytime soon, as their mutual interests are wedded tightly together. For all the Rhean contempt towards their partner, the reality remains that Titan's infrastructure, population, and general economy far outstrip that of the Rhean Divisional Authority.
