Fedan is a rich, pre-agricultural world with a moderate population over a hundred million, but not yet at a billion sophonts in size.

  • The world's agricultural industry is growing and some economists forecast an explosion in this world's agribusiness in the near future as new agro-technology and a more capable labor force are imported.
  • This is a rich world with a prosperous and thriving world economy.
  • This world has high-grade living conditions with a good climate and a non-harmful environment. As such, this world is much sought after with large queues for immigration here.
  • This a "low technology" world with technology competency well below technology standards for Charted Space.
  • It is a member of the Firstworlds in the Velous Subsector of Far Home Sector.

System Data[edit]

Vanticar-Fedan System[edit]

The primary is Vanticar, a hot white main sequence star. It has a luminosity of 16 Sols, a mass of 2.1 Sols, and a diameter of 2.505 million km. The inner system consists of (II) a trace atmosphere inner world, (III) a vacuum inner world, (V) a corrosive atmosphere inferno world, and (VI) a dense atmosphere stormworld – orbital positions (I) and (IV) are empty. (VII) Fedan orbits within the habitable zone and is designated the mainworld. (VIII) a very thin atmosphere hospitable world, (IX) a large gas giant, (X) a ringed small gas giant, (XI) a small ice giant, and (XII) a broad icy planetoid belt form the outer system. Many of the worlds retain satellites.

Mainworld Data[edit]

(VII) Fedan[edit]

(VII) Fedan is designated the mainworld. It orbits Vanticar at a mean distance of 5.1 AU (763 million km), within the habitable zone. It has an orbital period of 7 years 346 days and a rotation period of 24.5 hours. The axial tilt is 17 degrees. Fedan has a diameter of 9,087 km, a density of 5.47 g/cm³, and a surface gravity of 0.71 G. The world is geologically active. Its atmosphere is rated as Dense, with a mean surface pressure of 2.12 bar and a composition of 78% nitrogen (N2), 21% oxygen (O2), and 1% argon (Ar), water vapor (H2O), carbon dioxide (CO2), neon (Ne) and other trace gases. Approximately 77% of the surface is covered in seas of liquid water: average tidal ranges exceed 0.3m. Mean surface temperature: 25°C. The atmosphere is very active and strong weather systems driven by the star and the oceans sweep across the globe. The climate is seasonal.


Fedan retains a single natural satellite, a cratered vacuum worldlet named Gozan:

(VIIa) Gozan (UWP H200000-0, orbiting at 25 Diameters/225,000 km)

Mainworld geography and topography[edit]

Total surface area: 259 million km², Water surface area: 199 million km², Land surface area: 60 million km².

Native Lifeforms[edit]

The hot stormworld lying in orbital position (VI) (within the H– region of the inner system) has primitive native life, consisting entirely of microscopic cyanobacteria-parallels that exist in any location where they can find even a minimal trace of shelter and moisture. Their metabolic functions maintain the process of atmospheric renewal.

Fedan, the mainworld, has extensive, abundant native life, with organisms inhabiting every ecological niche. Their metabolic functions drive the process of atmospheric renewal.

The cold marginally hospitable world lying in orbital position (VIII) (within the H+ region of the outer system) has primitive native life, consisting entirely of microscopic cyanobacteria-parallels that exist in any location where they can find even a minimal trace of shelter and warmth. Their metabolic functions maintain the process of atmospheric renewal.

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

History & Background (Dossier)[edit]

No information yet available.

World starport[edit]

Fedan has a Class D Starport, a poor quality installation which has few of the 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 only a downport, unless this is a trade port or system with an hostile environment mainworld.

World technology level[edit]

Fedan possesses a Technology Level of TL–4.

World government[edit]

Fedan has a Balkanized Government. There is no central world government. The world has several governments competing for control of the world. These may be allies, cooperating, competitors, or at war with each other.

Central hive-cities each controlling a territory containing smaller hive communities.
