System Data

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

• The mainworld.
• x12 secondary rocky worlds.
• x3 gas giants.

Mainworld Data

The mainworld orbits within the star's Habitable Zone.

• It lies within the zone's prime H region.
• It receives moderate levels of stellar energy.

Mainworld Size (S)

Imperish 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)

Imperish has a pressure of 1.50 to 2.49 atmospheres. While a Dense Atmosphere requires no 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)

Imperish has 85-95% of its surface covered by liquid water with a few small continents, and a number of islands and archipelagos. Dry land is limited. Wilderness refueling is possible.

Satellites:

Imperish retains three small vacuum moons.

• The worlds orbit once every few weeks.

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

Abundant, diverse native life filling every available ecological niche. Its metabolic functions drive the process of atmospheric renewal.

History & Background (Dossier)

Imperish is a frontier, a wild and lonely place that rarely sees visitors. Many of the planets and moons within the system have never had an intelligent being visit them.

• Information about the system is limited.
• The resources of the system are largely untapped.

The system is unpopulated.

• Commercial traffic is extremely rare: the system sees very few visiting ships.
• Commo only picks up natural background noise and static.
• There are no active navigation beacons.

Note that social data, though only 40 years old, may be out of date: previously undocumented groups may now inhabit the system and maintain their own culture, forms of government, and systems of law.

• Verified updated data is constantly sought.

World Starport (St)

Imperish does not have a starport. The Class X Starport is an indication that no starport exists in the system. There are no facilities or services available, and no site marked for landing.
