Jump map from [1]

Qatan is a poor, nonindustrial world.

  • As a nonindustrial world, it requires extensive imports of outside technology to maintain a modern, star-faring society. The need to import most manufactured and high technology goods drives the price of these goods up in the open market.
  • This world has few prospects for economic development.
  • It is a member of The Last Line in the Tsorva Subsector of Halcyon Sector, which is part of the Distant Fringe.

Astrography and Planetology[edit]

This star system is detailed using the Fringian Variant System Description.

  • The Qatan system is a part of the Vey Trace.

System Data[edit]

Muncible-Qatan System[edit]

The primary is Muncible, an ordinary red main sequence star. It has a luminosity of 0.04 Sols, a mass of 0.489 Sols, and a diameter of 764,000 km. (I) Qatan orbits in the habitable zone and is designated the mainworld. (II) a trace atmosphere hospitable world, (III) a vacuum iceworld, (IV) an exotic atmosphere bigworld, and (V) a vacuum iceworld form the outer system. Only the bigworld retains satellites.

Rand Subsystem[edit]

The companion is Rand, a dim red subdwarf star. It orbits Muncible at a distance of 9.8 AU (orbital position (VIII), 1.466 billion km) and has an orbital period of 43 years 248 years. It has a luminosity of 0.011 Sols, a mass of 0.154 Sols, and a diameter of 356,000 km. (I) a vacuum iceworld, (II) a vacuum iceworld, and (III) an exotic atmosphere radworld form the outer system. None of the worlds have satellites.

Mainworld Data[edit]

(I) Qatan[edit]

(I) Qatan is designated the mainworld and orbits Muncible at a mean distance of 0.21 AU (31.4 million km), within the habitable zone. It has an orbital period of 50 days 6 hours: it is tidally locked to the primary. The axial tilt is 5.5 degrees. Qatan has a diameter of 7,814 km, a density of 5.72 g/cm³, and a surface gravity of 0.63 G. The world is geologically active. Its atmosphere is rated as Thin, with a mean surface pressure of 0.54 bar and a composition of 80% nitrogen (N2), 18% oxygen (O2), 1% carbon dioxide (CO2), and 1% argon (Ar), water vapor (H2O), neon (Ne) and other trace gases. Approximately 18% of the surface is covered in seas and lakes of liquid water: average tidal ranges exceed 0.25m. Mean surface temperature: -19°C. The atmosphere is slow and weak weather systems, driven by the star, crawl across the globe. The climate is static.

Mainworld Geography and Topography[edit]

Total surface area: 192 million km², Land surface area: 118 million km², Water surface area: 35 million km². The high levels of atmospheric carbon dioxide act as a greenhouse gas, increasing the average surface temperatures on the world. Much of the equator, where temperatures average around 0°C, is covered by the Beltwaters, linked shallow seas and wetlands with a high salinity. They are surrounded by icy rubble fields that give way to the Ragged Wastes to the north, and to the Long Desolation, a series of dormant volcanic peaks, in the south. The polar regions are arid and intensely cold. Some geologically active regions have far warmer climates, though the atmosphere in these areas is often tainted by relatively high levels of carbon dioxide, carbon monoxide, sulfur dioxide and other gases of volcanic origin.

  • The world experiences libration, which causes the star to move in the sky and periodically rise and fall above the horizon in the Twilight region.

Native Lifeforms[edit]

Qatan, the mainworld, has extensive native life, consisting of microscopic organisms, stromatolite-parallels and primitive flora that are tolerant of the low temperatures and can be found in almost every ecological niche. Their metabolic functions drive the process of atmospheric renewal.

History & Background (Dossier)[edit]

World starport[edit]

Qatan has a routine quality starport.

  • A Class-C Starport Facility has minimal if any shipyards and can only perform extremely limited repair work.
  • This facility has many very skilled personnel who can perform surprisingly sophisticated repair work despite the limited facilities.
  • This facility has refueling infrastructure and limited refining capabilities. One may purchase unrefined fuel here.
  • Starports of this class rarely have both a Lowport and a Highport.

World technology level[edit]

Qatan possesses a Technology Level of TL–5.

  • Common Communication technologies for this TL include: Telephone, radio, and television.
  • Common Power Generation technologies for this TL include: Electricity, hydrocarbon internal combustion, and the most fundamental atomic energy.
  • Common Transportation technologies for this TL include:
    • Land: Ground cars or automobiles and tracked vehicles.
    • Water: Large ships and submersibles with steel hulls.
    • Air: Early aircraft including seaplanes and very early unmanned rockets.

World government[edit]

Qatan has a Corporate or Company government.

  • Government is by a company managerial elite and citizens are typically company employees.
  • The typical power source of this government is an Oligarchy.
  • The typical power structure of this government is a Hegemony.
