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. The outer of the two is named Jayhon.

Mainworld Data

The planet has a standard oxygen-nitrogen atmosphere tainted by airborne micro-organisms and a chilly climate.

It orbits within its star's habitable zone.

• It receives moderate levels of stellar energy.

Mainworld Size (S)

Persephone is a Meso World between 10,400km and 12,000km in diameter. The world has a standard gravity between 0.7G and 0.9G. The horizon will appear about 4.7km away.

Mainworld Atmosphere (A)

Persephone 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.

• It experiences low temperatures.

Mainworld Hydrosphere (H)

Persephone has 45-55% of its surface covered by liquid water. Wilderness refueling is possible.

Mainworld Geography and Topography

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

(Blank map, predominantly dry world.)

History & Background (Dossier)

The system forms an important and heavily traveled link between Lunion and Glisten subsectors. The Scout Way Station uses Jayhon, the outer gas giant, as its main fuel source and supplies much of the fuel required for the port as well.

World Starport (St)

Persephone 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.

• The world is host to an Imperial Way Station.

World Government (G)

Persephone 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.

Persephone is ruled by an oligarchic Council of Merchants that has made itself hereditary. The mainworld's starport is large and its associated markets often contain many rare commodities.

World Law (L)

Persephone 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.
