Isa is a poor, nonindustrial hellworld with a population struggling to survive in an inhospitable environment.

• Hellworlds often offer daily, and sometimes even hourly, life-threatening situations to their inhabitants. Survivors often develop intense survival skills and tend to be grim realists.
• It requires extensive imports of outside technology to maintain a modern, star-faring society.
• It is a Non-Aligned world dominated by human sophonts located in the Siridor 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.
• It is closely associated with the Gulf of Siridor.
• It is considered a member of the Wilder Stars.

Description (Astrography & Planetology)

Stellar Data

System Data

A diagram indicating the positions of all of the major worlds and satellites in the system. Distances are noted in AU.

• Extended system data is available.

Primary System

• The Mainworld
• x1 gas giant

Secondary System
(1.6 AU from primary).

• x2 secondary rocky worlds

Circumbinary Worlds

• x1 secondary rocky world
• x1 planetoid belt
• x2 gas giants

Jump Shadow

The Jump Shadow of the star lies at 0.073 AU. The mainworld orbits beyond the safe jump distance.

Mainworld Data

Isa is tidally locked to its primary star.

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

Mainworld Size (S)

Isa is a Small World between 2,400km and 4,000km in diameter. The world has low gravity between 0.1G and 0.17G. The horizon will appear about 2.5km away.

Mainworld Atmosphere (A)

Isa 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 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.

Mainworld Hydrosphere (H)

Isa has 05-15% of its surface covered by liquid water or ice. Wilderness refueling will be difficult. 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

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

(Blank map, predominantly dry world.)

History & Background (Dossier)

Isa is a backwater that rarely sees visitors. Many of the planets and moons within the system have never been visited by an intelligent being.

• Information about the system is limited.
• The resources of the system are untapped.

Note that social data, though only 40 years old, may be out of date: previously undocumented groups may now inhabit the system and maintain their own culture, forms of government, and systems of law.

• Verified updated data is constantly sought.

World Starport (St)

Isa has a Class C Starport, an average quality installation which features amenities including unrefined fuel for starships, some brokerage services for passengers and cargo, and a variety of ship provisions. There is a shipyard capable of doing maintenance and other kinds of repair. Ports of this classification generally have only a downport, unless this is a trade port or system with an hostile environment mainworld.

World Population (P)

Isa has a population of 40,000 sophonts (tens of thousands).

• This is a Nonindustrial World, too small to support the complete chain of production of most goods from start to finish.

World Technology Level (T)

Isa 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 (G)

Isa 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.

World Law (L)

Isa 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. Machine guns, other automatic weapons, portable energy weapons, and other military weapons, body pistols, explosives, and poison gas are typically regulated or prohibited.
