Lon Mardos is a nonindustrial hellworld with a population struggling to survive in an inhospitable environment.

  • Hellworlds often offer daily, and sometimes even hourly, life-threatening situations to their inhabitants. Survivors often form intense survival skills and tend to be grim realists.
  • It requires extensive imports of outside technology to maintain a modern, star-faring society.
  • It is a Non-Aligned world dominated by human sophonts located in the Alasim Subsector of Halcyon Sector.

System Data[edit]

Blucher-Lon Mardos System[edit]

The primary is Blucher, a hot yellow-white giant star. It has a luminosity of 45.8 Sols, a mass of 4 Sols, and a diameter of 8.293 million km. The inner system consists of (I) a vacuum worldlet, (II) a vacuum inner world, (III) a very thin atmosphere inner world, (IV) an exotic atmosphere stormworld, (V) a corrosive atmosphere inferno world, and (VI) a corrosive atmosphere inferno world. (VII) Jaxan, a small gas giant, orbits within the habitable zone: (VIIb) Lon Mardos is its outer satellite and is designated the mainworld. (VIII) a corrosive atmosphere inferno world, (IX) a dense stony planetoid belt, (X) a ringed very large gas giant, (XI) a large gas giant, and (XII) a small ice giant form the outer system. Many of the worlds retain satellites.

(VII) Jaxen[edit]

(VII) Jaxen is a small gas giant that orbits Blucher at a mean distance of 4.92 AU (736 million km), within the habitable zone, and has an orbital period of 5 years 155 days. It has a diameter of 66,000 km and an atmosphere consisting of 90% hydrogen (H2), 10% helium (He), and less than 1% methane (CH4), carbon monoxide (CO), ammonia (NH3), water vapor (H2O) and other trace gases. It is a heavily banded tan-yellow color and contains significant traces of sulfur compounds. It retains a family of two major satellites.


Jaxen retains two major satellites:

(VIIa) Nurtaw (UWP F310000-0, orbiting at 7 Diameters/460,000 km)
(VIIb) Lon Mardos (designated the mainworld, orbiting at 15 Diameters/990,000 km)

Mainworld Data[edit]

(VIIb) Lon Mardos[edit]

(VIIb) Lon Mardos is the outer of the two major moons of (VII) Jaxon and is designated the mainworld. It orbits its parent world at a mean distance of 15 diameters (990,000 km), with an orbital period of 107 days 9 hours: it is tidally locked to Jaxon. The axial tilt is 12 degrees relative to Jaxon. Lon Mardos has a diameter of 10,099 km, a density of 7.03 g/cm³ and a surface gravity of 1.01 G. Tidal stresses caused by the gravitational pull of Jaxon cause frequent geological activity. Lon Mardos retains an atmosphere rated as Exotic, with a surface pressure of 3.85 bar and a composition of 95% nitrogen (N2), 3% carbon dioxide (CO2), 1% methane (CH4), and 1% argon (Ar), water vapor (H2O), neon (Ne), hydrogen (H2), ethane (C2H6), acetylene (C2H2), diacetylene (C4H2), propane (C3H8) and other trace gases. The world has no hydrosphere. Mean surface temperature: 71°C. The climate is rated as Very Hot and is static, with no seasonal changes during the local year. The atmosphere is extremely active and violent weather systems driven by the star surge across the globe.

Mainworld Size (S)[edit]

This world is a Meso World between 8,800km and 10,400km in diameter. The world has a standard gravity between 0.6G and 0.8G. The horizon will appear about 4.4km away.

Mainworld Atmosphere (A)[edit]

This world has an Exotic Atmosphere and possesses an unusual gas mix which requires the use of oxygen tanks, but protective suits not necessary, but are recommended. TL–8 or more advanced survival gear is required to settle this world.

Mainworld Hydrosphere (H)[edit]

This world has no free-standing water or ice on the surface. Wilderness refueling isn't possible on this world. Water for the inhabitants needs to be imported and extensively recycled. These worlds are classified Desert World or a Hell World depending on their atmosphere.

Mainworld Geography and Topography[edit]

Total surface area: 320 million km².

Native Lifeforms[edit]

Blucher-Lon Mardos System[edit]

World starport[edit]

Lon Mardos has a Class A Starport, an excellent quality installation which includes all the expected amenities including refined fuel for starships, brokerage services for passengers and cargo, and a variety of ship provisions. There is a shipyard capable of doing annual maintenance, overhauls and other kinds of repair, and construction of both starships and non-starships. Most ports of this classification have both a Highport and a Downport.

  • Peace footing (government modifier x0.8). Port Capacity: 4800 dTons


Port facilities within the system include:

World technology level[edit]

Lon Mardos possesses a Technology Level of TL–11 or TL-B in Hexadecimal Notation.

World government[edit]

Lon Mardos is governed by a Corporate Polity with a single corporation with a typical corporate structure as a government. A company town, or world. The typical corporate run world usually has a single purpose. Examples include mining, agriculture, or other kinds of resource extraction. But rather than a simple base of operations, there are facilities for housing workers and their families including hospitals, schools, and other infrastructure. How, or if, the children of the workers are incorporated into the workforce varies with companies. The corporation running the world may be a subsidiary of a larger interstellar corporation.
