Datrillian is a nonindustrial world, that requires extensive imports of outside technology to maintain a modern, star-faring society.

• In a technological universe, societies without industrial capability generally suffer as nearly all manufactured and high tech goods must be brought in at significant cost.
• 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 District 268 Subsector of Spinward Marches Sector.

• It is a mainworld which is a satellite of either a gas giant or another world.
• It is a balmy tropical world, with a climate of high temperatures.

System Data

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

• The mainworld.
• x7 secondary rocky worlds.
• x1 gas giant.

Mainworld Data

Datrillian, the largest moon of a huge gas giant, is ruled by nobility who claim to be descended from Gram Sword Worlders.

The mainworld and its gas giant primary orbit within the star's Habitable Zone.

• They lie within the zone's prime H region.
• They receive moderate levels of stellar energy.
• The gas giant is "puffy", warm and swollen due to the energy it receives from the star.

Mainworld Data

Mainworld Size (S)

Datrillian is a Meso World between 5,600km and 7,200km in diameter. The world has low gravity between 0.32G and 0.46G. The horizon will appear about 3.6km away.

Mainworld Atmosphere (A)

Datrillian has a pressure of 0.10 to 0.42 atmospheres. The very thin pressures require a respirator or Oxygen Mask. 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 Respirator Combination Mask. Some taints may require more protective equipment. TL–5 or more advanced survival gear is required to settle this world.

• It experiences high temperatures.

Mainworld Hydrosphere (H)

Datrillian has 65-75% 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)

Datrillian 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.

World Population (P)

Datrillian has a population of 8,000,000 sophonts (millions).

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

Urbanization

The population lives in one large domed city on the shore of Datrillian’s second ocean. Due to the violent nature of the gas giant, the only easily available fuel available is from the seas and the king has decreed that all ships must pay double the normal cost for fuel.

World Technology Level (T)

Datrillian 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)

Datrillian is governed by Self-Perpetuating Oligarchy. A single family or small group provides the leadership and important positions in the government. These positions are inherited by member of the group or their family members. The organization may be a monarchy, with titles passed to family members, or a plutocracy where inheritance of the family fortune includes government position. Alternatively, the organization may be a more typical government apparatus, only with positions of power inherited.

• The world is ruled by a king.

World Law (L)

Datrillian 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.
