Mestra is a poor, nonindustrial desert hellworld with a population struggling to survive in an inhospitable environment.

  • Hellworlds often offer daily, and sometimes hourly, life-threatening situations to their inhabitants. Survivors often form intense survival skills and tend to be grim realists.
  • This world has no free-standing water.
  • It requires extensive imports of outside technology to maintain a modern, star-faring society. Having to import most manufactured and high tech goods drives the price up for these items at this world.
  • It is a Non-Aligned world dominated by human sophonts located in the Orret Subsector of Far Home Sector.

Astrography and Planetology[edit]

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

  • The supergiant primary star of the Demon's Eye system and the huge Demon's Eye Nebula that surrounds it, lying a few parsecs to spinward, are clearly visible in the sky.

System Data[edit]

Smolder-Mestra System[edit]

The primary is Smolder, 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) Mestra, designated the mainworld, (II) a vacuum worldlet, (III) a vacuum iceworld, (IV) an exotic atmosphere bigworld, and (VII) a vacuum iceworld with a highly elliptical orbit form the outer system – orbital positions (V) and (VI) are empty. None of the worlds retain satellites.

Mainworld Data[edit]

(I) Mestra[edit]

(I) Mestra is designated the mainworld. It orbits Smolder at a mean distance of 0.16 AU (23.9 million km), within the outer system. It has an orbital period of 47 days 8 hours: it is tidally locked to Smolder. The axial tilt is 3 degrees. Mestra has a diameter of 5,023 km, a density of 3.05 g/cm³, and a surface gravity of 0.22 G. Tidal stresses generated by the gravitational pull of Smolder cause frequent geological activity. Its atmosphere is rated as Thin, Tainted, with a mean surface pressure of 0.54 bar and a composition of 84% nitrogen (N2), 13% abiotic oxygen (O2), 1% carbon dioxide (CO2), 1% argon (Ar), and 1% water vapor (H2O), carbon monoxide (CO), ozone (O3), neon (Ne) and other trace gases. The taint is caused by the low percentage of atmospheric oxygen. Mestra is a desert world: less than 1% of the surface is covered in lakes of water kept liquid by geothermal activity. Mean surface temperature: -72°C. The atmosphere is slow and weak weather systems driven by the star drift across the globe. The climate is rated as Very Cold and is static, with no seasonal changes during the local year.

Mainworld Geography and Topography[edit]

Total surface area: 79 million km², Land surface area: 78.5 million km², Water surface area: 0.5 million km². The rugged Bloodshadow highlands cover the northern pole and much of the northern hemisphere, giving way to sharply ridged dunes and broad flatlands around the equator. The southern hemisphere alternates between low hills and wide rubble-strewn depressions. The southern pole consists of fractured canyons and ravines. Small lakes of water can be found within lowland areas, kept liquid by geothermal activity: they are surrounded by large wetland areas that give way to permafrost.

  • The oxygen in the atmosphere is abiotic in origin, produced by the photocatalytic reaction between UV energy radiating from the star and titanium dioxide (TiO2), which is found in surface minerals such as ilmenite.
  • Mestra is a Twilight Zone World.
  • 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]

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

History & Background (Dossier)[edit]

No information yet available.

World starport[edit]

Mestra 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[edit]

Mestra 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]

Mestra 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.
