System Data[edit]

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

  • The mainworld. It orbits the primary-secondary pair within the habitable zone.
  • x2 secondary rocky worlds. Both orbit the primary-secondary pair.
  • x4 gas giants. Three orbit the the primary-secondary pair, one orbits the distant tertiary star.

Mainworld Data[edit]

Mainworld Size (S)[edit]

Mettari is a Meso World between 8,800km and 10,400km in diameter. The world has a standard gravity between 0.6G and 0.8G. The horizon will appear about 4.4km away.

Mainworld Atmosphere (A)[edit]

Mettari has a pressure of 0.43 to 0.70 atmospheres. The Thin Atmosphere does not require survival gear although it may be hard on sophonts not accustomed to it.

Mainworld Hydrosphere (H)[edit]

Mettari 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.

History & Background (Dossier)[edit]

Comp-Prog-Dav-R-Deitrick-Starter-Trav-Page-16 16-July-2018a.jpg

Mettari is a member of the Rhamsteppe-Mongrebi Main. It is a part of the Adni Run region of the Main.

It is a part of the Darmine Cultural Region, created within rimward Zarushagar Sector by order of Emperor Artemsus in the years immediately following the Ilelish Pacification Campaign.

World Starport (St)[edit]

Mettari has a Class D Starport, a poor quality installation which has few of the 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 only a downport, unless this is a trade port or system with an hostile environment mainworld.

World Population (P)[edit]

Mettari has a population of 20 sophonts (tens).

  • This is a Low Population World and the population would be too low to sustain itself without significant outside assistance. This may represent a transient population such as the crew of a starship, the final survivors of a dying colony, an advance team setting up to receive colonists, or a small outpost where establishing a colony is not the primary objective.

Linguistic Topography[edit]

The most commonly heard languages are:

World Technology Level (T)[edit]

Mettari 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)[edit]

Mettari has no central government or substantial government apparatus; 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 Law (L)[edit]

Mettari 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. Portable energy weapons, body pistols, explosives, and poison gas are typically regulated or prohibited.
