Jump map from Travellermap.com

Cogri is a nonindustrial, rich oceanic water world.

• It is covered with very deep oceans with less than 1% of its land above sea level.
• The inhabitants of this world live on the roughly 1% 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.
• Its economy and population are already quite rich with highly desirable living conditions.
• It is a member of the Third Imperium in the Lanth Subsector of Spinward Marches Sector in the Domain of Deneb.
• This is a cold world with an overall climate that is at the lower temperature range of human-congruous sophont endurance.
• Cogri is a member of the Spinward Main.

System Data

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

• The mainworld.
• x2 secondary rocky worlds.
• x3 planetoid belts.
• x2 gas giants.

Mainworld Data

Cogri has a harsh, frozen climate; the planet is covered in a thick, fractured outer crust of pack ice and icebergs, with little solid rock to build upon.

The mainworld orbits within the star's Habitable Zone.

• It lies within the zone's colder outer H- region.
• It receives relatively low levels of stellar energy.

Mainworld Size (S)

Cogri is a Big World between 15,200km and 16,800km in diameter. The world has a standard gravity between 1.1G and 1.5G. The horizon will appear about 5.7km away. Vessels with only 1G of thrust should avoid landing on this world.

Mainworld Atmosphere (A)

Cogri has a pressure of 0.71 to 1.49 atmospheres. A Standard Atmosphere does not require survival gear and will likely be easy for most sophonts to breathe.

• It experiences very low temperatures.

Mainworld Hydrosphere (H)

Cogri 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.

• The world-ocean is littered with icebergs and pack ice.

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)

Cogri has a Class C Starport, an average quality installation which features amenities including unrefined fuel for starships, some brokerage services for passengers and cargo, and a variety of ship provisions. There is a shipyard capable of doing maintenance and other kinds of repair. Ports of this classification generally have only a downport, unless this is a trade port or system with an hostile environment mainworld.

World Population (P)

Cogri has a population of 4,000,000 sophonts (millions).

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

Urbanization

Half the population clusters about the starport, while the remainder lives in settlements built atop every scrap of available ice-crusted rock.

Linguistic Topography

The most commonly heard languages are:

• Anglic, one of the two official languages of the Imperium.
• Vilani, one of the two official languages of the Imperium.

World Technology Level (T)

Cogri 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 gills.
  • 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 (G)

Cogri 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)

Cogri has a low law level. There are few laws, covering only important areas. There may be few or no law enforcement officers, the expectation is citizens will bring law breakers to the attention of the Judicial system. Legal proceedings will be fast, with few people involved. For interactions outside of the framework of the laws, cultural norms dominate. Machine guns, other automatic weapons, portable energy weapons, and other military weapons, body pistols, explosives, and poison gas are typically regulated or prohibited.

Imperial Landed Nobility

Cogri, as a member world of the Third Imperium, holds the estate of an Imperial Landed Knight who acts as an Imperial representative to the world, and the fiefdom of a member of the Imperial Landed Nobility, who oversees affairs regarding the world at an Interstellar and Imperial level.

• It holds the estate of an Imperial knight, the Imperial representative to the world.
• It holds the fiefdom of an Imperial baron.

Trade Data

• Importance: 0 (unimportant)

World Economy

• Resources: D (very abundant)
• Labor: 5 (hundreds of thousands)
• Infrastructure: 4 (very limited)
• Efficiency: -3 (poor)

Ice-burrowing “submarines” are used to reach the clear liquid water far beneath the floating crust of ice, and to harvest the life found around geothermal vents there. Chemicals are extracted from the vent deposits by deep-diving teams. Conditions are harsh, but the locals are skilled and hardworking, and enjoy a high standard of living.

World Culture

• Heterogenity: 3 (monolithic)
• Acceptance: 6 (aloof)
• Strangeness: 2 (typical)
• Symbols: 6 (somewhat concrete)
