System Data[edit]

Farsite-Estos System[edit]

The primary is Farsite, a dim red main sequence star. It has a companion, Glamis, a red subdwarf, orbiting at 2350 AU. Farsite has a luminosity of 0.001 Sols, a mass of 0.114 Sols and a diameter of 280,000 km. (I, II, III) three rocky vacuum worlds, (IV) Estos, designated the mainworld, (V) a large gas giant, (VI) an exotic atmosphere world, and (VII) a small gas giant form the outer system. Both of the gas giants and many of the rocky worlds retain families of satellites.

Glamis Subsystem[edit]

The primary is Glamis, an ordinary red subdwarf star orbiting Farsite at 2350 AU. It has a luminosity of 0.0038 Sols, a mass of 0.215 Sols and a diameter of 187,000 km. (I) a rocky thin atmosphere world, (II) an icy thin atmosphere world, and (III) a large gas giant form the outer system. The gas giant retains a family of satellites.

Mainworld Data[edit]

(IV) Estos[edit]

(IV) Estos is designated the mainworld. It orbits Farsite at a mean distance of 0.97 AU (145 million km), it has an orbital period of 2 years 22 days and a rotation period of 19.25 hours. The axial tilt is 7.5 degrees. Estos has a diameter of 6,188 km, a density of 5.36 g/cm³, and a surface gravity of 0.47 G. Its atmosphere is rated as Trace, with a mean surface pressure of 0.03 bar and a composition of 91% carbon dioxide, 7% nitrogen: 1% argon, and 1% oxygen, carbon monoxide, nitrogen oxide, neon and other trace gases. Approximately 11% of the surface is covered in a crusting of water-ice. Mean surface temperature: -235° C.

Satellite:[edit]

(IV) Estos retains a single large natural satellite, a vacuum moon named Nyoka.

(IVa) Nyoka (Y301000-0, orbiting at 25 diameters/155,000 km)

Mainworld geography and topography[edit]

Total surface area: 120 million km², Land surface area: 106 million km², Ice Coverage: 14 million km².

Native lifeforms[edit]

No worlds within the Estos system have native life.

History & Background (Dossier)[edit]

No information yet available.

World starport[edit]

Estos 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]

Estos 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[edit]

Estos 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.
