Yedan is a poor, non-agricultural and nonindustrial world.
- It requires extensive imports of outside technology to maintain a modern, star-faring society.
- It is unable to produce quality foodstuffs and must import them.
- It has few prospects for economic development. Life here is drastically bleak.
- It is a Non-Aligned world dominated by human sophonts located in the Frell Subsector of Halcyon Sector.
Astrography and Planetology
This star system is detailed using the Fringian Variant System Description.

System Data
Volsojo-Yedan System
The primary is Volsojo, a dim red main sequence star. It has a luminosity of 0.0055 Sols, a mass of 0.302 Sols, and a diameter of 444,000 km. (I) a sparse icy planetoid belt, (II) a vacuum iceworld, (III) Woocha, a small gas giant: (IIIb) Yedan is its largest moon and is designated the mainworld, (IV) a small ice giant, (V) a large gas giant, (VI) a vacuum iceworld, (VII) a vacuum worldlet, and (VIII) an exotic atmosphere bigworld form the outer system. Most of the worlds retain satellites.
(III) Woocha
(III) Woocha is a small gas giant that orbits Volsojo at a mean distance of 0.68 AU (101.7 million km) and has an orbital period of 372 days 17 hours. It has a diameter of 28,000km and is a bright blue colour. It retains a family of three major satellites of which the second, (IIIb) Yedan, is designated the mainworld.
Mainworld Data
(IIIb) Yedan
(IIIb) Yedan is the second of the three major moons of Woocha and is designated the mainworld. It orbits its parent world at a mean distance of 25 diameters (700,000 km) and has an orbital period of 98 days 0 hours: it is tidally locked to Woocha. It has an axial tilt of 0 degrees relative to Woocha. It has a diameter of 6,681 km, a density of 4.26 g/cm³ and a surface gravity of 0.41 G. Tidal stresses caused by the gravitational pull of Woocha cause frequent seismic activity. It retains an atmosphere rated as Very Thin, Tainted, with a surface pressure of 0.18 bar and a composition of 90% nitrogen (N2), 8% abiotic oxygen (O2), 1% carbon dioxide (CO2), and 1% argon (Ar), water vapor (H2O), ozone (O3), neon (Ne) and other trace gases. The taint is caused by the extremely low percentage of oxygen and high levels of carbon dioxide. Around 26% of the surface is covered in thick ice sheets and around 3% is covered in small seas of water kept liquid by salinity and geothermal activity: tidal ranges are negligible. Mean surface temperature: -75°C. The atmosphere is extremely sluggish and marginal weather systems driven by the star drift across the surface. The climate is static.
Mainworld Geography & Topography
Total surface area: 140 million km², Land surface area: 99 million km², Ice Coverage: 38 million km², Water surface area: 3 million km². Much of the surface of Yedan is arid dust plains, gravelly flatlands and rippled dunes, divided by low mountain ranges and dotted with rugged highland regions. Much of the surface is covered in glacial sheets, frozen lakes and deep layers of frozen gas. Geologically active areas have small bodies of water, kept liquid by geothermal activity. The lakes are marked by geysers that tower many kilometers into the sky and spread gas and ice crystals over thousands of kilometers.
- 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.
Native lifeforms
Yedan does not have native life and no offworld organisms are known to have colonised the world. The atmosphere is partially renewed by the worlds geothermal activity but it is gradually depleting.
History & Background (Dossier)
No information yet available.
World starport
Yedan has a Class B Starport, a good quality installation which includes all the expected amenities including refined fuel for starships, brokerage services for passengers and cargo, and a variety of ship provisions. There is a shipyard capable of doing annual maintenance, overhauls and most kinds of repair, and construction of non-starships. Most ports of this classification have both a Highport and a Downport.
World technology level
Yedan possesses a Technology Level of TL–10 or TL-A in Hexadecimal Notation.
- Common Communication technologies for this TL include: Holovision, Personal Global Communications, and advanced Translators.
- Common Power Generation technologies for this TL include: Increasingly advanced fusion plants and advanced fuel cells.
- Common Transportation technologies for this TL include:
- Land & Water: Grav belts and maturing gravcraft.
- Air: Greatly improved hybrid grav-aircraft.
- Space: Improved interplanetary spacecraft (System Craft).
- FTL: Jump Drive-1.
World government
Yedan is governed by a Feudal Technocracy. Society divides itself based on the technical requirements of the society. Each of these functions are granted as a fief to an individual or group. Leadership of these fiefs determines the head of the government.
World military

World economy
- Resources: A (Abundant)
- Labor: 5 (Hundreds of thousands)
- Infrastructure: 6 (Limited)
- Efficiency: +1 (Average)
