Coos is a nonindustrial fluid world.

• A fluid world has an oceanic geography consisting of heavily contaminated water or a substance such as ammonia, methane, hydrocarbons, or other exotic liquid.
• 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.
• This world is a member of the Trelyn Domain (the Duchy of Trelyn) located in the Coos Subsector of Vanguard Reaches Sector.

• This is a "high technology" world with technology achievements at, near, or above the standard for Charted Space.
• The world serves as the subsector capital with the significant extra trade and prestige associated with that role.
• This world has an exploration base, which is similar to an Imperial Scout base, capable of handling explorer personnel and exploratory starships.
• This world has a colony at Egin XI.

System Data

The worlds of the system have been surveyed. They consist of:

• The mainworld.
• x7 secondary rocky worlds.
• x1 planetoid belt.
• x3 gas giants.

Mainworld Data

Mainworld Size (S)

Coos is a Big World between 13,600km and 15,200km in diameter. The world has a standard gravity between 1G and 1.3G. The horizon will appear about 5.4km away. Vessels with only 1G of thrust should avoid landing on this world.

Mainworld Atmosphere (A)

Coos has an Exotic Atmosphere and possesses an unusual gas mix which requires the use of oxygen tanks. Additionally, protective suits, while not necessary, are recommended. TL–8 or more advanced survival gear is required to settle this world.

Mainworld Hydrosphere (H)

Coos has 55-65% of its surface covered by liquid water or ice heavily tainted with other substances, which makes it dangerous, corrosive, or toxic. Wilderness refueling will be difficult. Water for the inhabitants needs to be imported and extensively recycled. These worlds may be Hell Worlds.

• The water on the surface may be unsuitable for use or consumption without extensive filtering and purification.
• Refining for fuel may cause issues with shipboard purification plants.

Mainworld Geography and Topography

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

History & Background (Dossier)

To comply with the terms of its Imperial charter, the Allarton Corporation, the Imperial corporation underpinning the Trelyn Domain, is limited to operations exclusively within the Trelyn Subsector of Vanguard Reaches Sector. Allarton officials and representatives may occasionally conduct business on other worlds of the Domain.

• Corporate operations in other areas of the Vanguard Reaches are conducted under the wholly owned Pan-Melesien Company.
• Corporate operations in the Far Frontiers Sector are conducted under the wholly owned Artesian Company, based at Yster.

Both subsidiary companies may be active on worlds far beyond their official operating areas.

Negotiations with the Pan-Melesien Company at Coos resulted in Karelian joining the Trelyn Domain in 972, keeping control of its colonies at Weslaco, Surtun, and Yalgoo, while granting independence to Tithira.

The jump drives for Allarton's Stellaris-class vessels are produced on Coos.

World Starport (St)

Coos has a Class A Starport, an excellent 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 other kinds of repair, and construction of both starships and non-starships. Most ports of this classification have both a Highport and a Downport.

• The world is host to a Trelyn Exploration Base.

World Population (P)

Coos has a population of 9,000,000 sophonts (millions).

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

World Technology Level (T)

Coos possesses a Technology Level of TL–13 or TL-D in Hexadecimal Notation.

• Common Communication technologies for this TL include: Holovideo recorders.
• Common Power Generation technologies for this TL include: Miniature super-batteries, prototype collectors, advanced fusion plants.
• Common Transportation technologies for this TL include:
  • Land, Water & Air: Personal G-Tubes and advanced gravcraft.
  • Space: Advanced interplanetary spacecraft (System Craft).
  • FTL: Jump Drive-4.

World Government (G)

Coos is governed by a Representative Democracy where government leadership is by representatives elected by eligible voters. What determines an eligible voter varies. The representatives determine policy, including selecting members of the bureaucracy. There can be referenda, votes by eligible voters on specific subjects.

World Law (L)

Coos 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. All firearms except shotguns, and anything more destructive, are typically regulated or prohibited.
