Uffan is a rich, agricultural garden world with a near-ideal, utopian environment conducive to most sophonts.

  • This world-system hosts a Military Base, usually associated with military ground forces, which may be located on or off-world.

System Data[edit]

Uffan-Vush System[edit]

The primary is Vush, an ordinary white main sequence star. It has a luminosity of 4.42 Sols, a mass of 1.38 Sols and a diameter of 2.032 million km. The inner system consists of (I) a vacuum worldlet, (II) a very thin atmosphere inner world, (III) a corrosive atmosphere inferno world, and (IV) an exotic atmosphere bigworld. (V) Uffan orbits within the habitable zone and is designated the mainworld. (VI) a large gas giant, (VII) a ringed large gas giant, (VIII) an exotic atmosphere bigworld, and (IX) a dense icy planetoid belt form the outer system. Many of the worlds retain satellites.

Landax Subsystem[edit]

The companion is Landax, an ordinary red subdwarf star lying approximately 890 AU from Vush. It has a luminosity of 0.0074 Sols, a mass of 0.134 Sols and a diameter of 399,000 km. (I) a vacuum iceworld and (II) a ringed small gas giant form the outer system. The gas giant retains a single large satellite.

Mainworld Data[edit]

(V) Uffan[edit]

(V) Uffan is designated the mainworld. It orbits Vush at a mean distance of 1.6 AU (241 million km), it has an orbital period of 629 days 6 hours and a rotation period of 37.3 hours. The axial tilt is 2 degrees. Uffan has a diameter of 13,052 km, a density of 5.47 g/cm³, and a surface gravity of 1.01 G. The world is geologically active. It has an atmosphere rated as Standard, with a mean surface pressure of 0.99 bar and a composition of 79% nitrogen (N2), 20% oxygen (O2), and 1% argon (Ar), water vapor (H2O), carbon dioxide (CO2), neon (Ne) and other trace gases. Approximately 64% of the surface is covered in oceans of liquid water: average tidal ranges are around 0.1m. Mean surface temperature: 21°C. The atmosphere is dynamic and weather systems, driven by the star and the oceans, roll across the globe. The climate is static.


Uffan retains two natural satellites, a tiny vacuum worldlet named Strak and a cratered vacuum worldlet named Nenavid:

(Va) Strak (UWP YS00000-0, orbiting at 45 Diameters/585,000 km)
(Vb) Nenavid (UWP Y100000-0, orbiting at 50 Diameters/655,000 km)

Mainworld Geography & Topography[edit]

Total surface area: 535 million km², Land surface area: 193 million km², Water surface area: 342 million km². Dalee and Phorge, two small continents, lie in the northern and southern tropics respectively, and the oceans are studded with subcontinental landmasses, large islands and chains of archipelagos. Much of the surface land area is concentrated within the equator and the temperate zones.

Native Lifeforms[edit]

Uffan-Vush System[edit]

Uffan, the mainworld, has extensive, abundant native life, with complex organisms inhabiting every ecological niche. Their metabolic functions drive the process of atmospheric renewal. Native fauna comes in many shapes and sizes but the single most common body pattern is bilateral HS-BT-LN-LN-T, with a skeleton interior, blood fluids, and skin exteriors. Native lifeforms have a generally similar chemistry to humans and can be consumed, though their flavor and texture is an acquired taste.

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

Landax Subsystem[edit]

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

History & Background / Dossier[edit]

Uffan is one of the original Seven Colonies and has been populated for far more than three millennia.

World Starport[edit]

Uffan has a good quality starport.

  • A Class B Starport Facility has not very well developed shipyards and is only capable of producing spaceships.
  • This facility has many very skilled personnel who can perform not only major repair work, but overhaul work as well.
  • This facility has advanced refueling and refining infrastructure. One may purchase practically any kind of refined fuel here.
  • Almost every starport of this class possesses both a Lowport and a Highport. Such ports rarely have more than one of each kind of port.

World Technology Level[edit]

Uffan possesses a Technology Level of TL–9.

  • Common Communication technologies for this TL include: Fiber optics and satellite communication and data networks.
  • Common Power Generation technologies for this TL include: Early fusion power.
  • Common Transportation technologies for this TL include:
    • Land: Ultra high-speed trains and early grav vehicles.
    • Water: High efficiency sailcraft, multihulled seacraft, improved artificial gears.
    • Air: Tiltrotorcraft, exotic VTOL's, PARWIG, and rocket-assisted suborbitals.
    • Space: SSTO spacecraft, early military spacecraft (System Craft), and interstellar STL starships
    • FTL: Prototype Jump Drive-1.

World Government[edit]

Uffan has a Representative Democracy government.

  • It is a government by elected representatives.
  • The typical power source of this government is a Republic.
  • The typical power structure of this government is a Unitary State .

World Military[edit]

Uffan has military units referred to collectively as the Uffan Strategic Space Forces.

World Economy[edit]

  • Resources: B (Abundant)
  • Labor: 6 (Millions)
  • Infrastructure: A (Extensive)
  • Efficiency: +3 (Improved)

Trade Data[edit]

Uffan is largely agricultural, though there is extensive small-scale local industry primarily geared to supporting agriculture.

Uffan produces large amounts of livestock and processed animal products.

World Demographics[edit]

Population 41,400,000

  • Humaniti (Human races)
    • Solomani (Major Race): 40.6 million (98% of the population), descended from the first human settlers on the world.
  • Native Non-Human Races:
    • Hoppers: 671,000 (1.62% of the population), concentrated within hives in human communities.
    • Meroquan: 72,000 (less than 0.02% of the population), largely concentrated within the city of Celestras.
    • Temelik: 10,500 (less than 0.01% of the population), widely dispersed across the world.


Almost the entire population are concentrated on the continent of Dalee. The chief cities are:

  • Carvo (population 11.2 million), the capital and the site of the surface starport.
  • Celestras (population 6.5 million)
  • Paradim (population 4.5 million)

The cities are surrounded by smaller satellite towns. An efficient and well-maintained transportation network connects all of the major communities.

The continent of Phorge is divided into enormous family ranches that raise livestock. The rest of the land surface of the world is primary wilderness.

World Culture[edit]

  • Homogeneity: 8 (Discordant)
  • Acceptance: A (Very friendly)
  • Strangeness: 6 (Very distinct, a proud heritage with ancient traditions)
  • Symbols: B (Abstract, often denoting strong group affiliations)
