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.
Astrography and Planetology
- This world lies within the Rissa Gateway region.

System data
The system primary is Yarid, an ordinary red main sequence star. It has a dwarf companion, Berk. (I) Rissa orbits in the habitable zone and is designated the mainworld. (II, III, IV) three rocky vacuum worlds and (V) an exotic atmosphere world form the outer system. Rissa and the exotic atmosphere world retain satellites. Berk, the companion star, orbits at (XII) 305 AU. It retains (I) a sparse planetoid belt.
(I) Rissa
(I) Rissa is designated the mainworld. It orbits Yarid at a mean distance of 0.2 AU (27.9 million km), it has an orbital period of 46 days 15 hours, and a rotation period of 27.25 hours. 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. Its atmosphere is rated as Thin, Tainted with a mean surface pressure of 0.62 bar and a composition of 75% nitrogen, 23% oxygen, 2% argon, carbon dioxide, neon and other trace gases. The world experiences high levels of radiation originating from the star: protective measures must be taken at all times. Approximately 18% of the surface is covered in oceans 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 and weather patterns follow regular cycles during the local year.
Satellites:
Rissa retains two satellites:
- (Ia) Rasenik, UWP H322000-0, orbiting at 7 Diameters (95,000 km)
- (Ib) Pomardo, UWP G201436-A, orbiting at 35 Diameters (475,000 km)

World starport
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.

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
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.
