Prevo is a low-population world with a population of less than 10,000 sophonts in size.

• This world has yet to take off economically or otherwise and the population remains low for reasons largely unknown.
• It is a member of the Regency of Muirimi in the Zebylono Subsector of Iphigenaia Sector.

• This world is a "Twilight Zone World", a planet that is tidally-locked to its star. It has a hot side that permanently faces the star, a cold side that permanently faces away, and a narrow twilight zone in-between.
• This world-system hosts a Naval Base, usually associated with military starships, which may be located on or off-world.

Description (Astrography & Planetology)

Prevo has a solitary primary star.

• It is an orange main sequence.

System Data

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

• The mainworld.
• x4 secondary rocky worlds.
• x4 gas giants.

Mainworld Data

Prevo is a Twilight Zone World.

• One side of the world permanently faces towards the star and one side permanently faces away.
• In the narrow region between permanent night and permanent day, the primary star eternally hangs on the horizon.

The mainworld orbits within the star's Habitable Zone.

• It lies within the zones prime H region.
• It receives moderate levels of stellar energy.

• The world orbits inside the stars Jump Shadow.

Mainworld Size (S)

Prevo 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)

Prevo 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 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.

• The world has an abiotic oxygen atmosphere.
• Oxygen is produced by photocatalytic conversion of surface materials by stellar energy.
• Fresh surface material is constantly exposed through processes such as seismic activity, volcanism, or erosion.
• The oxygen rapidly depletes from the atmosphere through oxidization with surface materials: a rough equilibrium between production and depletion exists.
• The world has a low oxygen taint: the percentage of oxygen in the atmosphere varies according to the density of global cloud cover.

Mainworld Hydrosphere (H)

Prevo has 35-45% of its surface covered by liquid water. There will be a number of small seas or one larger body of water. Wilderness refueling is possible.

• The vast oceans are shallow and sluggish.

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 dry world.)

Native Lifeforms

No native life: the world has an abiotic oxygen atmosphere.

History & Background (Dossier)

Prevo is an important naval facility and training area. Areas under military control are subject to strict rules and regulations.

• It is a member world of the Regency of Muirimi.
• It has been settled for centuries.
• The resources of the system are being exploited.

The population are culturally Muirimi.

• The inhabitants can trace their origins back to the central Asian and Indian subcontinent regions of Terra.
• The majority are followers of Sitaraism, a form of star-worship.

A few organizations and private interests are active within the system.

• Commercial traffic is fairly frequent: ships regularly arrive and depart.
• Commo regularly picks up signals and private chatter. Communications are in Naiurdu and Riftian Anglic.
• A number of commercial navigation beacons will be active.
• A few vessels may be operating among the other worlds and moons that make up the system.
• Naval vessels may be active in the system.

The world formed part of an ancient Muirimi state called the Pietten Confederation.

• The Confederation practiced a harsh form of Sitaraism that placed many restrictions on its followers.
• The polity was considered belligerent and frequently had disputes with its neighbours, particularly the Republic of Georgia.
• Despite fervent internal protest, the Confederation and its member worlds chose to join the Regency upon its formation.

Note that social data, though only 40 years old, may be out of date.

• Verified updated data is constantly sought.

World Starport (St)

Prevo 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.

• A Naval Base is sited within the system.

World Demographics (P)

Prevo has a population of 400.

Urbanization

A single advanced central facility with a few outlying structures and compounds.

• Structures and facilities are sealed against local environmental conditions.
• Other than a few restricted areas, almost all of the surface of the world is wilderness.

World Technology Level (T)

Prevo 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)

Prevo has no central government for the world, an Anarchy. The largest governmental structure would be a family, tribe, or single clan. The largest group will be between 50 and 100 individuals, and there may be dozens to hundreds of them. This governmental structure can be stable over long periods of time if the population remains small or geographically separated.

World Military

Privately retained security personnel.

World Law (L)

Prevo has no law in practice. It is an Anarchy. On many worlds, this by itself justifies an Amber Zone advisory. 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.
