Ribis is a low population, fluidic hellworld of less than 10,000 sophonts struggling to survive in an inhospitable environment.

• A fluid world has an oceanic geography consisting of heavily contaminated water or a substance such as ammonia, methane, hydrocarbons, or other exotic liquid.
• Hellworlds often offer daily, and sometimes hourly, life-threatening situations to their inhabitants.
• It is a member world of the Sorority of Hygiea located in the Galaxa Subsector of Mavuzog 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 is a cold world with an overall climate that is at the lower temperature range of human-congruous sophont endurance.

Description (Astrography & Planetology)

Stellar Data

Ribis is a binary star system.

• Both are red main sequence stars.
  • They are close companions.

Ribis has two stars in the star system.

System Data

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

• The mainworld.
• x2 secondary rocky worlds.
• x1 planetoid belt.
• x2 gas giants.

Mainworld Data

Ribis has a circumbinary orbit, circling around both stars and receiving their combined energy output.

It is tidally locked to the binary stars.

• It experiences libration - a regular wobble - as it orbits, causing the two stars to move in the sky.

600 px

It orbits towards the outer edge of the two star's combined habitable zone.

• It receives relatively low levels of stellar energy.

Mainworld Size (S)

Ribis 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)

Ribis has an Exotic Atmosphere and possesses an unusual gas mix which requires the use of oxygen tanks. Additionally, protective suits, while not necessary, are recommended. TL–8 or more advanced survival gear is required to settle this world.

• It experiences low temperatures.

Mainworld Hydrosphere (H)

Ribis has 05-15% of its surface covered by liquid water or ice heavily tainted with other substances, which makes it dangerous, corrosive, or toxic. Wilderness refueling will be difficult. Water for the inhabitants needs to be imported and extensively recycled. These worlds may be Hell Worlds.

• The water on the surface may be unsuitable for use or consumption without extensive filtering and purification.
• Refining for fuel may cause issues with shipboard purification plants.

Mainworld Geography and Topography

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

• Locally, detailed maps may be available.

(Blank map, exotic world.)

Exotic primitive native life occupying a few specialist ecological niches. Its metabolic functions help drive the process of atmospheric renewal.

• Native lifeforms are cryophilic - they thrive in low temperatures.
• They will rapidly die in environmental conditions suitable for humans.

History & Background (Dossier)

World Starport (St)

Ribis 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)

Ribis has a population of 50 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.

World Technology Level (T)

Ribis 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)

Ribis is governed by a Corporate Polity, having a single corporation with a typical corporate structure as a government. Essentially, this is a "company town" (or world). The typical corporate-run world usually has a single purpose. Examples include mining, agriculture, or other kinds of resource extraction. But rather than a simple base of operations, there are facilities for housing workers and their families, including hospitals, schools, and other infrastructure. How, or if, the children of the workers are incorporated into the workforce varies with companies. The corporation running the world may be a subsidiary of a larger interstellar corporation.

As a member of the Sorority of Hygiea, this government pays tax to the polity leadership at Fal Zaria.

World Law (L)

Ribis 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.
