Seos is an agricultural, nonindustrial world still lacking adequate means to expand its economy.

• As an agricultural world, this world is a near-ideal environment for producing quality foodstuffs of plant, animal, and other forms. Quality foodstuffs are a major export commodity for this world.
• It requires extensive imports of outside technology to maintain a modern, star-faring society. Having to import most manufactured and high tech goods drives the price up for these items at this world.
• It is a member of the Empire of Varroerth in the Nanthou Subsector of Windhorn Sector, which is part of the Vargr Extents.

• This is a "low technology" world with technology competencies well below standard for Charted Space.

Mainworld Data

Mainworld Size (S)

Seos is a Meso World between 7,200km and 8,800km in diameter. The world has a standard gravity between 0.4G and 0.57G. The horizon will appear about 4km away.

Mainworld Atmosphere (A)

Seos has a pressure of 0.71 to 1.49 atmospheres. While a Standard Atmosphere does not require survival gear this atmosphere also contains an unusual taint such as disease, a hazardous gas mix, pollutants, or sulfur compounds which requires the use of a Filter Mask. Some taints may require more protective equipment. TL–3 or more advanced survival gear is required to settle this world.

Mainworld Hydrosphere (H)

Seos has 55-65% of its surface covered by liquid water. It has significant large liquid bodies. Wilderness refueling is possible.

Mainworld Geography and Topography

No centrally held map of the world exists within AAB Library Data records.

(Blank map, predominantly watery world.)

History & Background (Dossier)

World Starport (St)

Seos 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 Population (P)

Seos has a population of 2,000,000 sophonts (millions).

• This is a Nonindustrial World, too small to support the complete chain of production of most goods from start to finish.
• The population entirely consists of Vargr.

World Technology Level (T)

Seos possesses a Technology Level of TL–5.

• Common Communication technologies for this TL include: Telephone, radio, and television.
• Common Power Generation technologies for this TL include: Electricity, hydrocarbon internal combustion, and the most fundamental atomic energy.
• Common Transportation technologies for this TL include:
  • Land: Ground cars or automobiles and tracked vehicles.
  • Water: Large ships and submersibles with steel hulls.
  • Air: Early aircraft including seaplanes and very early unmanned rockets.

World Government (G)

Seos is governed by a Civil Service Bureaucracy. The leadership of the government takes another form (democracy, dictatorship, oligarchy), but the bureaucracy leadership influences policy. The government leadership may select the bureaucracy leadership, but not its membership. Usually the governmental leadership is divided, or incapable of setting policy, and the bureaucracy provides a stabilizing influence. This ruling bureaucracy may be the full government bureaucractic apparatus or a section with limited jurisdiction but considerable influence, like the military.

World Law (L)

Seos has a moderate level with laws covering many areas of government and interaction. These laws are simple enough that most people can act as their own advocate, though for serious issues a professional is recommended. Law enforcement officials will be present, but not in great numbers. Personal concealable firearms, and anything more destructive, are typically regulated or prohibited.
