Planetary flag of Brahe

Brahe is an ocean planet in the Copernicus system. First colonized alongside Iolaus by sleeper ships c. 2132, contact was temporarily lost during the war between the Terran Commonwealth and the Ares Confederation. Since contact was reestablished during the formation of the Sol Central Government, Brahe has been a strong supporter of the SCG and an advocate for further expansion into unexplored space. With only 12% of the planet's surface being usable landmass, Brahe's economy is mostly founded on the tourism that the extensive coasts attract, and research done in surface and underwater labs. The Zeng-Hu corporation in particular has strong ties to Brahe's genetic research labs, and many Brahese government officials hold positions within the company.


Due to its highly-elliptical orbit, Brahe’s climate fluctuates wildly between extremes, ranging from blistering heat and tropical storms in the hotter seasons to dangerously-low temperatures during its winters. For human life, unassisted survival on the planet’s surface is possible only during Brahe’s more temperate months – during the inhospitable off-seasons, residents retreat to off-world community stations or to one of many aquatic habitation centers below Brahe’s waves.

Geographically, Brahe is dominated by massive salt water oceans, which account for nearly 90% of the planet’s surface. Compared to the volatile climate above, these oceans maintain relatively stable temperatures year-round. While the surfaces of these oceans are often wracked by violent blizzards and hurricanes, Brahe’s subaquatic depths remain consistently habitable – nearly all of the planet’s native life exists below the surface. This unique biosphere has long been a major point of interest among the Brahese scientific community; today, the planet boasts some of the most advanced research programs in the field of marine science in all of human space.


The first settlements on Brahe were subaquatic laboratories, sponsored by the Terran Commonwealth’s early colonization efforts. The planet’s thriving marine ecosystem, coupled with its position on the then-frontier of deep space, made Brahe an invaluable scientific outpost – over the next seventy years, corporate and Commonwealth investment would see the expansion of these laboratories into a sprawling network of subaquatic research complexes. The first terrestrial structures – what would later become New Aarhus – would be built during this time period.

With the onset of the Ares War, Brahe and its sister planet Iolaus found themselves cut off from Sol. While Iolaus rallied, Brahe – having been entirely reliant on off-planet investment and imported supplies – nearly collapsed, with massive shortages rocking the planet and many research complexes falling into disrepair. Brahe survived this period of hardship only thanks to the aid from its neighboring Iolaus, whose exports still form the backbone of Brahe’s economy to this day. After the reestablishment of contact with Sol in 2230, Brahe’s corporate leaders leapt at the chance to reintegrate with Sol, and have retained close ties with the broader corporate research sector ever since.

Since reintegration, many companies – most prominently Zeng-Hu Pharmaceuticals – sought to reclaim and expand their holdings on Brahe, buying up abandoned settlements and repurposing them for research or, later, as exclusive travel destinations. Brahe’s unique climate and abundant shorelines proved highly lucrative; it was not long before Zeng-Hu would build its first Zeng-Hu leisure park, an entirely self-contained city catering to wealthy Solar tourists in Brahe’s temperate months, and evacuating its staff and residents to off-planet community stations and subaquatic habitation centers during the off-season.

Today, Zeng-Hu boasts two such cities: ZH Paradise and ZH Eden. Brahe’s third terrestrial city – its capital, New Aarhus – falls under mixed public and private ownership, but likewise boasts a large tourist sector. In recent years, Zeng-Hu has purchased much of New Aarhus’s above-water and near-shore property; many suspect the corporation has plans of converting the city into a third leisure park in the near future.


Subaquatic habitation centers make up a majority of Brahe’s settlements. Almost fractal in nature, these settlements have grown around the many research labs dotting the planet’s ocean floor – residential communities sprawl outwards from the centers of these labs, with small habitation dorms housing scientists and support staff alike. Other habitation centers only operate during Brahe’s off-months, housing the staff and semi-permanent residents of the planet’s above-ground cities; these complexes tend to be distinctly more utilitarian, sporting narrow hallways and minimal greenery. Some corporate staff continue to work in these seasonal communities, performing maintenance and service duties – those who cannot are allotted enough company credit to subsist until the next tourist season begins.  

In contrast, Brahe’s leisure cities are built for high-end living and entertainment. These cities are designed for short, idyllic stays, with the companies that manage them going to great lengths to maintain their image. Souvenir shops, upscale restaurants, and exclusive entertainment centers line the pristine city streets, with outrageously expensive vacation properties sitting along the coast. Few tourists suspect that beneath the veneer, these cities are constructed almost entirely of weather-reinforced plasteel and concrete rebar – materials made necessary for the cities to survive the planet’s brutal storms during the off-season.

To date, only New Aarhus and the Zeng-Hu leisure cities of ZH Paradise and ZH Eden are the only notable settlements above Brahe’s ocean. Discounting a handful of small private islands, the remainder of Brahe’s colonies lie below the sea. The planet’s ocean is host to a large network of subaquatic lab-cities and habitation centers – the largest of these are Labravo, a research complex dating back to Brahe’s initial colonization, and the Winters Research Center, a newer facility constructed by Zeng-Hu’s genetics department.


Brahe’s government is run by a world parliament, with smaller courts running local affairs in individual settlements. The Brahese parliament is held in New Aarhus’ capitol building during the planet’s temperate months, and shuttled to a self-sufficient station in Brahe’s orbit during the inhospitable off-season.

Since the end of the Ares Conflict, Zeng-Hu has taken a major role in Brahe’s government – a significant portion of the planet’s installations are held by Zeng-Hu, and many Brahese government officials hold positions within the company. While Zeng-Hu staff are not legally obligated to support their company in the political sphere, those who do not are often subject to retribution from their employers, typically with little hope of reprisal. Two of the three above-ground cities fall under Zeng-Hu’s direct ownership – furthermore, the corporation owns shares in a majority of businesses available in Brahe’s subaquatic zones, leaving residents dependent on Zeng-Hu for everything from high-end goods to basic groceries and medical services.

Over the past thirty years, however, Zeng-Hu’s grasp on the planet has begun to loosen. Scrutiny from Sol – coupled with a corresponding dip in planetary tourism – has motivated Zeng-Hu to relax some of its more dubious policies; in the latest parliamentary elections, Zeng-Hu retained its majority by a mere two seats. Since these elections, the anti-corporate movement among the Brahese public has only strengthened, with many calling for greater workers’ rights. In response, Zeng-Hu has tightened control over its employees' political activity and announced a new, “better” employee benefit plan – which has yet to be seen by the public.


Brahe’s economy revolves around its tourism and research sectors; the planet’s genetic research labs are second to none, and Brahe’s Zeng-Hu facilities have achieved multiple breakthroughs in antibiotics and therapeutic medicine in the past decade alone. Permanent residents who aren’t employed directly in research or in one of the planet’s many hotels, restaurants, or other tourist attractions invariably find themselves working in support and service roles: maintaining Brahe’s vast subaquatic complexes and towering leisure cities, filing paperwork, sweeping the streets, or simply fetching coffee. During off-seasons, however, a large portion of workers in the tourist sector find themselves unemployed – those who cannot turn to off-planet work or full-time station maintenance are left to weather the summers and winters on a basic subsistence stipend, living in subaquatic corporate apartment complexes.

Given the nature of its economy, Brahe is heavily reliant on foreign investment and imported goods – the latter coming almost exclusively from Iolaus. Iolan imports are delivered nearly year-round, weather permitting; without them, Brahe would likely fall into ruin.
