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 is a Non-Aligned world dominated by human sophonts located in the Frell Subsector of Halcyon Sector.

System data

The system primary is Volsojo, a dim red main sequence star: the entire system is considered to be outer zone. Volsojo retains (I) a sparse icy planetoid belt, (II) a small vacuum world, (III) a large gas giant: (IIIb) Yedan is its largest satellite and is designated the mainworld, (IV, V) two small gas giants, (VI, VII) two small vacuum worlds, and (VIII) a final large exotic atmosphere world. All of the gas giants and the exotic atmosphere world retain satellites.

(IIIb) Yedan

(IIIb) Yedan is the second of the three major moons of Woocha, orbitting its parent world at a mean distance of 25 diameters (1.08 million km), with an orbital period of 32 days 9 hours and a rotation period of 18.5 hours. It is designated as the mainworld. It has a diameter of 6681 km, a density of 5.26 g/cm³ and a surface gravity of 0.5 G. It retains an atmosphere rated as very thin, tainted, with a surface pressure of 0.18 bar and a composition of 88% nitrogen, 10% oxygen, and 1% argon, carbon dioxide, neon and other trace gases. The atmospheric taint is caused by the very low percentage of oxygen. Around 29% of the surface is covered in ice sheets and small seas of heavily saline liquid water kept melted by geothermal activity. Tidal stresses caused by the gravitational pull of Woocha cause seismic activity. The climate is very cold and weather patterns follow regular cycles during the local year. Yedan is extremely cold, with temperatures averaging around -75ºC.

Mainworld Geography & Topography

Arid dust plains, gravelly flatlands, low mountain ranges, rugged highland regions. Around 20% of the surface is covered in glacial sheets and frozen lakes. Around 10% of the surface is covered in sheets of liquid water,

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.
