System Data[edit]

Nosata System[edit]

The primary is Nosata, a dim red main sequence star. It has a luminosity of 0.004 Sols, a mass of 0.273 Sols, and a diameter of 414,000 km. (I) a very thin atmosphere radworld, (II) a trace atmosphere iceworld, (III) an exotic atmosphere bigworld, (IV) a sparse icy planetoid belt, (V) a ringed large gas giant, (VI) a trace atmosphere iceworld, and (VII) a vacuum worldlet form the outer system. Most of the worlds retain satellites.

Mendezo-Eeren System[edit]

The companion is Mendezo, an ordinary red main sequence star lying approximately 2300 AU from Nosata. It has a luminosity of 0.0136 Sols, a mass of 0.3626 Sols, and a diameter of 551,000 km. (I) a vacuum worldlet, (II) a sparse icy planetoid belt, (III) Costyn, a small gas giant: (IIIa) Eeren is its only major moon and is designated the mainworld, (IV) a trace atmosphere iceworld, (V) a large gas giant, and (VI) a small ringed gas giant form the outer system. Many of the worlds retain satellites.

(III) Costyn[edit]

(III) Costyn is a small gas giant that orbits Mendezo at a mean distance of 0.71 AU (106.2 million km) and has an orbital period of 362 days 21 hours. It has a diameter of 33,000 km and is a mottled blue-green colour. It retains a single major satellite, (IIIa) Eeren, which is designated the mainworld.

Mainworld Data[edit]

(IIIa) Eeren[edit]

(IIIa) Eeren is the only major moon of (III) Costyn and is designated the mainworld. It orbits its parent world at a mean distance of 15 diameters (495,000 km), with an orbital period of 53 days 16 hours: it is tidally locked to Costyn. The axial tilt is 6 degrees. Eeren has a diameter of 2,608 km, a density of 5.72 g/cm³ and a surface gravity of 0.21 G. Tidal stresses caused by the gravitational pull of Costyn cause frequent geological activity. It retains an atmosphere rated as Trace, with a surface pressure of 0.07 bar and a composition of 98% nitrogen, 1% carbon dioxide, and 1% argon, methane, water vapor, neon and other trace gases. Around 10% of the surface is covered in a crust of water ice. Mean surface temperature: 110°C. The atmosphere is static and very weak weather systems, largely the result of volcanic outgassing, ghost across the globe. The climate is static.

Mainworld geography and topography[edit]

Total surface area: 21.4 million km², Land surface area: 19.3 million km², Water surface area: 2.1 million km².

Native lifeforms[edit]

No world in the Eeren system is known to have native life.

History & Background (Dossier)[edit]

World starport[edit]

Eeren has a Class C Starport, an average quality installation which includes amenities including unrefined fuel for starships, some brokerage services for passengers and cargo, and a variety of ship provisions. There is a shipyard capable of doing maintenance and other kinds of repair. Ports of this classification generally have only a downport, unless this is a trade port or system with an hostile environment mainworld.

World technology level[edit]

Eeren possesses a Technology Level of TL–8.

  • Common Communication technologies for this TL include: Fiber optics, improved telephones, and satellite communication and data networks.
  • Common Power Generation technologies for this TL include: Improved geothermal and improved batteries.
  • Common Transportation technologies for this TL include:
    • Land: Advanced automobiles.
    • Water: Triphibians and early artificial gills.
    • Air: Improved helicopters and hypersonic jets.
    • Space: Space shuttles, early space stations, and improved interplanetary spacecraft (System Craft).

World government[edit]

Eeren has a Balkanized Government. There is no central world government. The world has several governments competing for control of the world. These may be allies, cooperating, competitors, or at war with each other.
