Cleistra is a poor, barren world with no overt population, government, or law level.
- This world could be populated if anyone had an inclination to do so...
- This dangerous world is designated an Amber Zone with an environment, laws, customs, life forms, or other conditions make it dangerous to visitors.
- It is a Non-Aligned world dominated by human sophonts located in the Abidal Subsector of Halcyon Sector.
Astrography and Planetology
This star system is detailed using the Fringian Variant System Description.
- The Cleistra system lies within a "shoal" region called the "Cleistra Bubble". Travel to the system presents a considerable risk to starships.

System Data
Sangax-Cleistra System
The primary is Sangax, 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) Cleistra, designated the mainworld, and (II) an exotic atmosphere bigworld form the outer system. Neither world retains satellites.
- The star experiences periodic flare activity.
Mainworld Data
(I) Cleistra
(I) Cleistra is designated the mainworld. It orbits Sangax at a mean distance of 0.18 AU (27 million km), it has an orbital period of 56 days 11 hours and a rotation period 49 days 16 hours. The axial tilt is 90 degrees: the world's northern pole points towards the star and it wobbles as it rotates. Cleistra has a diameter of 3,516 km, a density of 3.97 g/cm³, and a surface gravity of 0.2 G. Tidal stresses generated by Sangax heat the interior of the world and cause geological activity. Its atmosphere is rated as Very Thin, Tainted, with a mean surface pressure of 0.23 bar and a composition of 73% nitrogen (N2), 18% oxygen (O2), 7% carbon dioxide (CO2), 1% argon (Ar), and 1% water vapor (H2O), neon (Ne), and other trace gases. The taint is caused by the high percentage of atmospheric carbon dioxide and the relatively high levels of background radiation: emission rates exceed 2 rads per hour. Approximately 19% of the surface is covered in a crust of water-ice and frozen gases, though geologically active regions may have small areas of liquid water. Mean surface temperature: -158°C. Northern polar temperature: -62°C. The climate is rated as Very Cold and is static, with no seasonal changes during the local year. The atmosphere is extremely sluggish and minor weather systems, driven by the star, affect northern regions of the globe. Weather patterns closely match cycles within the star.
Mainworld geography and topography
Total surface area: 39.9 million km², Land surface area: 32.3 million km², Ice coverage: 7.6 million km². The Everdark mountains dominate the southern hemisphere and extend to the equator. The rugged northern temperate zone, called the Dawnlands, is marked by the Murtaugh Depression. It is formed by five huge, shallow impact craters spaced at regular intervals across the globe and linked by fractured canyons. They give way to the Powder Plains and the jagged northern Glarebright mountains.
- Oxygen contained deep within the world's interior is released by outgassing and serves to renew the atmosphere: it continuously reacts with surface materials and other atmospheric gases, gradually reducing the percentage of oxygen in the air. Experts predict that the atmosphere will be reduced to a trace in a few tens of million of years.
Native Lifeforms
Sangax-Cleistra System
Neither world in the system is known to have native life.
History & Background (Dossier)
No information yet available.
World starport
Cleistra has a Class E Starport, a frontier quality installation with few expected amenities. There is unrefined fuel for starships and a limited variety of ship provisions. There is no shipyard of any kind, but there may be parts and technical support for doing minor services and repair. Ports of this classification generally consist of a downport.
World technology level
Cleistra possesses a Technology Level of TL–0.
- These worlds often contain a Proto-Sophont species beginning to establish a nascent civilization and society.
- This world is in its Alpha Period and has not yet been interfered with by a higher technology civilization.
- Common Communication technologies for this TL include: Bodily communicative apparati, courier-runners, and smoke signals.
- Common Power Generation technologies for this TL include: Bodily muscle.
- Common Transportation technologies for this TL include:
- Land: Bodily locomotion, riding beasts, and litters or sedan chairs.
- Water: Swimming, rafts, and canoes.
- Air: Typically not available unless a bodily ability.
World government
Cleistra has no central government for the world, an Anarchy. The largest governmental structure would be a family, tribe, or single clan. The largest group will be between 50 and 100 individuals, and there may be dozens to hundreds of them. This governmental structure can be stable over long periods of time if the population remains small or geographically separated.
