Gas Giants 3

Ret Eslan 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 Esser Subsector of Divide Sector.

System Data[edit]

Simminal-Ret Eslan System[edit]

The primary is Simminal, a dim red main sequence star. It has a luminosity of 0.0025 Sols, a mass of 0.244 Sols, and a diameter of 334,000 km. (I) a sparse rocky planetoid belt, (II) Falarin, a large gas giant: (IIb) Ret Eslan, its outer satellite, is designated the mainworld, (III) a sparse icy planetoid belt, (IV) a large gas giant, (V) a vacuum worldlet, (VI) a small gas giant, and (VII) a vacuum worldlet form the outer system. Many of the worlds retain satellites.

(II) Falarin[edit]

(II) Falarin is a large gas giant that orbits Simminal at a mean distance of 0.38 AU (56.8 million km), within the habitable zone, and has an orbital period of 173 days 5 hours. It has a diameter of 62,000 km and an atmosphere consisting of 89% hydrogen (H2), 11% helium (He), and less than 1% methane (CH4), carbon monoxide (CO), ammonia (NH3), water vapor (H2O) and other trace gases. It is a pale green color with indistinct yellow bands. It retains a family of two major satellites.


Falarin retains two major satellites:

(IIa) Gar Vida (UWP Y4A0000-0, orbiting at 9 Diameters/560,000 km)
(IIb) Ret Eslan (designated the mainworld, orbiting at 20 Diameters/1.24 million km)

Mainworld Data[edit]

(IIb) Ret Eslan[edit]

(IIb) Ret Eslan is designated the mainworld. It orbits Falarin at a mean distance of 20 diameters (640,000 km) and has an orbital period of 80 days 3.5 hours: it is tidally locked to Falarin. The axial tilt is 2 degrees. Ret Eslan has a diameter of 6,233 km, a density of 4.99 g/cm³, and a surface gravity of 0.44 G. The world is flexed by tidal forces and is geologically active. Its atmosphere is rated as Very Thin, Tainted, with a mean surface pressure of 0.31 bar and a composition of 88% nitrogen, 9% oxygen, 2% carbon dioxide, and 1% argon, methane, neon and other trace gases: the taint is caused by the very low percentage of atmospheric oxygen, gases of volcanic origin and relatively high levels of background radiation. Approximately 16% of the surface is covered in lakes of liquid water and accumulations of water-ice. Mean surface temperature: -180°C. The atmosphere is sluggish and minor weather systems, driven by the star, crawl across the globe. The climate is static and weather patterns are influenced by local geography.

Mainworld Geography and Topography[edit]

Total surface area: 122 million km², Land surface area: 103 million km², Ice and Water surface area: 19 million km², of which approximately 3.7 million km² (3% of the surfaccxe) is liquid water. The surface is dotted with geologically active areas where temperatures are significantly warmer. Geysers of gas and superheated water, many kilometers in height, erupt from the worlds interior. The water freezes in the air, falling back to the surface as ice. Where this lands in geologically warmed areas it forms into small lakes: these are surrounded by extensive ice fields. Much of the rest of the world is rugged, arid and frigidly cold, dominated by sheer ridges, boulder fields and cratered terrain.

Native Lifeforms[edit]

Simminal-Ret Eslan System[edit]

Despite the very marginal conditions Ret Eslan has extensive native life, entirely consisting of extremophile single-celled cyanobacteria-equivalents that can be found in every geologically active area on the world and within surface ices. Their metabolic functions drive the process of atmospheric renewal.

History & Background (Dossier)[edit]

No information yet available.

World starport[edit]

Ret Eslan 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]

Ret Eslan 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]

Ret Eslan is governed by a Representative Democracy where government leadership is representatives elected by eligible voters. What determines an eligible voter varies. The representatives determine policy, including selecting members of the bureaucracy. There can be referendum, votes by eligible voters on specific subjects.
