Jump map from Travellermap.com

Thrace is a nonindustrial water world, which has 90% or more of its surface covered in an ocean of water.

• The inhabitants of this world live on the roughly 10% of exposed land mass, in underwater colonies, on city ships, or similar arrangements.
• As a nonindustrial world, it requires extensive imports of outside technology to maintain a modern, star-faring society. The need to import most manufactured and high technology goods drives the price of these goods up in the open market.
• It is a Non-Aligned world dominated by human sophonts located in the Alpha Subsector of Theta Borealis Sector.

• It orbits the tertiary star.
• It is a balmy tropical world, with a climate of high temperatures.

Description (Astrography & Planetology)

Stellar Data

Thrace is a trinary star system.

• The primary is a turbulent blue-white bright giant.
• The secondary is a white main sequence.
• The tertiary is a white main sequence.

Thrace has three stars in the star system.

System Data

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

• The mainworld.
• x5 secondary rocky worlds.
• x2 planetoid belts.
• x2 gas giants.

Mainworld Data

The mainworld orbits within the tertiary star's Habitable Zone.

• It lies within the zone's warmer inner H+ region
• It receives higher levels of stellar energy.

• The world orbits beyond the star's Jump Shadow.

Mainworld Size (S)

Thrace is a Meso World between 8,800km and 10,400km in diameter. The world has a standard gravity between 0.6G and 0.8G. The horizon will appear about 4.4km away.

Mainworld Atmosphere (A)

Thrace 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)

Thrace has 95-100% of its surface covered by liquid water with only a few islands and archipelagos. Wilderness refueling is possible. Such worlds are Water Worlds or Ocean Worlds.

Satellites:

Thrace retains a small vacuum moon.

• It orbits once every few days.

Mainworld Geography and Topography

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

• Locally, detailed maps may be available.
• Verified updated charts are constantly sought.
• Detailed survey data commands premium prices.

(Placeholder chart, predominantly watery world.)

Native Lifeforms

Primitive aquatic native life. Its metabolic functions drive the process of atmospheric renewal.

History & Background (Dossier)

The local population are supporters of the trade protection agreement known unofficially as "the protectorate". Coordinating largely remotely, these xenophobic societies mistrust "alien" goods, and are unfriendly (or perhaps more unfriendly) to non-protectorate members offering trade.

World Starport (St)

Thrace has a Class E Starport, a frontier quality installation with few 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 a downport.

Facilities

Port facilities within the system include:

• No information yet available.

World Technology Level (T)

Thrace possesses a Technology Level of TL–8.

• Common Communication technologies for this TL include: Fiber optics, improved telephones, and satellite communication and data networks.
• Common Power Generation technologies for this TL include: Improved geothermal and improved batteries.
• Common Transportation technologies for this TL include:
  • Land: Advanced automobiles.
  • Water: Triphibians and early artificial gills.
  • Air: Improved helicopters and hypersonic jets.
  • Space: Space shuttles, early space stations, and improved interplanetary spacecraft (System Craft).

World Government (G)

Thrace is governed by an Impersonal Bureaucracy. The leadership of the government takes another form (democracy, dictatorship, oligarchy), but the bureaucracy dictates government policy and its execution. Government leadership is reduced to little more than figureheads and does not select the bureaucracy leadership or its members.

World Military

No information yet available.

World Law (L)

Thrace has a moderate law 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, and anything more destructive, are typically regulated or prohibited.

World Economy

• Resources: C (very abundant)
• Labor: 5 (hundreds of thousands)
• Infrastructure: 1 (extremely limited)
• Efficiency: -3 (poor)

Trade Data

• Importance: -3 (very unimportant)

World Demographics (P)

Thrace has a population of 5,000,000

Urbanization

A central urban area surrounded by smaller satellite communities.

• Outlying areas have a few isolated structures or compounds.
• Almost all of the surface of the world is wilderness.

World Culture

• Homogeneity: 6 (harmonious)
• Acceptance: 3 (xenophobic)
• Strangeness: 5 (distinct)
• Symbols: 8 (somewhat abstract)
