Platen is a poor, low-population hellworld with a population less than 10,000 sophonts 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 is a Non-Aligned world dominated by human sophonts located in the Alasim Subsector of Halcyon Sector.

System Data[edit]

Cylin-Platen System[edit]

The primary is Cylin, 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 vacuum iceworld, (II) an exotic atmosphere bigworld, (III) Platen, designated the mainworld, (IV) a dense atmosphere stormworld, (V) a ringed large gas giant, (VI) a dense icy planetoid belt, (VII) a small gas giant, (VIII) a very thin atmosphere radworld, and (IX) a small ice giant form the outer system. Many of the worlds retain satellites.

Mainworld Data[edit]

(III) Platen[edit]

(III) Platen is designated the mainworld. It orbits Cylin at a mean distance of 0.59 AU (88.3 million km), within the outer system. It has an orbital period of 316 days 19 hours and a rotation period of 17.5 hours. The axial tilt is 38 degrees. Plate has a diameter of 6,754 km, a density of 6.23 g/cm³, and a surface gravity of 0.60 G. The world is geologically very active. Its atmosphere is rated as Thin, Tainted, with a mean surface pressure of 0.48 bar and a composition of 81% nitrogen (N2), 18% oxygen (O2), and 1% argon (Ar), water vapor (H2O), carbon dioxide (CO2), neon (Ne) and other trace gases. The taint is caused by relatively high levels of background radiation: emission rates exceed 3 rads per hour. Approximately 17% of the surface is covered in seas of water kept liquid by geothermal heat generated by subsurface radioactive materials: average tidal ranges exceed 0.25m. Mean surface temperature: -43°C. The climate is rated as Cold and experiences moderate seasonal changes during the local year. The atmosphere is sluggish and weak weather systems driven by the star drift across the globe.

Satellites[edit]

Platen retains two natural satellites, an ice-capped vacuum worldlet named Rogan and a very thin atmosphere radworld named Burk:

(IIIa) Rogen (UWP Y101000-0, orbiting at 9 Diameters/61,000 km)
(IIIb) Name (UWP Y120000-0, orbiting at 25 Diameters/170,000 km)

Mainworld Geography and Topography[edit]

Total surface area: 143 million km², Land surface area: 119 million km², Water surface area: 24 million km². Large areas of the surface are substantially warmer that the mean surface temperatures, being warmed by geothermal heat generated by subsurface deposits of radioactives.

Native Lifeforms[edit]

Cylin-Platen System[edit]

Platen, the mainworld, has primitive native life, consisting entirely of microscopic cyanobacteria-parallels that exist in any location where they can find liquid water and warmth. Their metabolic functions maintain the process of atmospheric renewal.

The stormworld lying in lying in orbital position (IV) (within the H+ region of the outer system) has primitive cryophile native life, consisting entirely of microscopic cyanobacteria-parallels that thrive in the harsh conditions. Their metabolic functions drive the process of atmospheric renewal.

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

History & Background (Dossier)[edit]

No information yet available.

World starport[edit]

Platen 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]

Platen possesses a Technology Level of TL–6.

World government[edit]

Platen has a Self-Perpetuating Oligarchy government.

  • It is a government by a restricted minority, with little or no input from the masses.
  • The typical power source of this government is an Oligarchy.
  • The typical power structure of this government is a Hegemony.
