Rissa is a poor, low-population hellworld with a population less than 10,000 sophonts struggling to survive in an inhospitable environment.
- Hellworlds often offer daily, and sometimes even hourly, life-threatening situations to their inhabitants. Survivors often form intense survival skills and tend to be grim realists.
- It is a Non-Aligned world dominated by human sophonts located in the Abidal Subsector of Halcyon Sector.
- This world-system hosts a Military Base, usually associated with military ground forces, which may be located on or off-world.
Description (Astrography & Planetology)[edit]
This star system is detailed using the Fringian Variant System Description.
- This world lies within the Rissa Gateway region.

System Data[edit]
Rissa-Yarid System[edit]
The system primary is Yarid, an ordinary red main sequence star. It has a luminosity of 0.04 Sols, a mass of 0.489 Sols and a diameter of 764,000 km. (I) Rissa orbits in the habitable zone and is designated the mainworld. (II) a thin atmosphere hospitable world, (III) a vacuum iceworld, (IV) a trace atmosphere iceworld, and (V) an exotic atmosphere bigworld form the outer system. Rissa and the bigworld retain satellites.
Berk Subsystem[edit]
The companion is Berk, a tiny dwarf star that orbits Yarid at a mean distance of 305 AU (orbital position (XII), 45.6 billion km) and has an orbital period of 7,600 years. It has a luminosity of 0.00003 Sols, a mass of 1.11 Sols and a diameter of 8,350 km. It retains (I) a sparse icy planetoid belt.
Mainworld Data[edit]
(I) Rissa[edit]
(I) Rissa is designated the mainworld. It orbits Yarid at a mean distance of 0.18 AU (27.1 million km), it has an orbital period of 39 days 22 hours: it is tidally locked to the primary. The axial tilt is 13.5 degrees. Rissa has a diameter of 7,844 km, a density of 5.53 g/cm³, and a surface gravity of 0.63 G. Tidal forces flex the world and it is geologically active. Its atmosphere is rated as Thin, Tainted with a mean surface pressure of 0.62 bar and a composition of 82% nitrogen, 17% oxygen, 1% argon, carbon dioxide, neon and other trace gases. The taint is caused by high levels of radiation originating from the star: protective measures must be taken at all times. Approximately 18% of the surface is covered in seas and lakes of liquid water: average tidal ranges exceed 0.5m. Mean surface temperature: -13°C. The atmosphere is sluggish and minor weather systems slowly cross the globe. The climate is seasonal.
Mainworld Size (S)[edit]
This world is a Meso World between 7,200km and 8,800km in diameter. The world has a standard gravity between 0.4G and 0.57G. The horizon will appear about 4km away.
Mainworld Atmosphere (A)[edit]
This world has a pressure of 0.43 to 0.70 atmospheres. While the thin atmosphere does not require survival gear 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 Mask. Some taints may require more protective equipment. TL–3 or more advanced survival gear is required to settle this world.
Mainworld Hydrosphere (H)[edit]
This world has 15-25% of its surface covered by liquid water or ice. There may be a few small seas. Wilderness refueling is possible. Water for the inhabitants needs to be imported and extensively recycled. These worlds are Hell Worlds or Poor Worlds depending on their atmosphere.
Mainworld geography and topography[edit]
Total surface area: 193 million km², Land surface area: 158 million km², Water surface area: 35 million km².
Native lifeforms[edit]
Rissa has extensive but primitive native life, consisting entirely of microscopic organisms that exist in any location where they can find even a minimal trace of water. Their metabolic processes maintain a cycle of atmospheric renewal.
History & Background (Dossier)[edit]
No information yet available.
World starport[edit]
Rissa 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.
World technology level[edit]
Rissa possesses a Technology Level of TL–10 or TL-A in Hexadecimal Notation.
- Common Communication technologies for this TL include: Holovision, Personal Global Communications, and advanced Translators.
- Common Power Generation technologies for this TL include: Increasingly advanced fusion plants and advanced fuel cells.
- Common Transportation technologies for this TL include:
- Land & Water: Grav belts and maturing gravcraft.
- Air: Greatly improved hybrid grav-aircraft.
- Space: Improved interplanetary spacecraft (System Craft).
- FTL: Jump Drive-1.
World government[edit]
Rissa is governed by a Corporate Polity with a single corporation with a typical corporate structure as a government. 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.
World military[edit]
The governing corporation has experimented with subsidizing their income with mercenary operations across the Distant Fringe. A typical example is Colonel Ryan's Rissian Regiment.
