Jump map from Travellermap.com

Semso 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 develop intense survival skills and tend to be grim realists.
• It is a Non-Aligned world dominated by human sophonts located in the Semso Subsector of Chiep Zhez Sector.

• 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

Semso is a binary star system.

• Both are red main sequence stars.

Semso has two stars in the star system.

System Data

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

• The mainworld.
• x6 secondary rocky worlds.
• x2 planetoid belts.
• x2 gas giants.

Mainworld Data

Semso orbits at the outer edge of the primary star's narrow habitable zone.

It has a slow rotation period: one local day is equivalent to 3.3 standard days (approximately 80 standard hours).

Mainworld Size (S)

Semso 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)

Semso 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 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.

• It experiences very low temperatures.

Mainworld Hydrosphere (H)

Semso 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.

• The world is crusted in frost and fractured ice.

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)

Semso is a remote outpost, a wild and lonely place on the frontier of settled space.

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

Semso 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)

Semso has a population of 200 sophonts (hundreds).

• This is a Low Population World and the population would be too low to sustain itself without moderate outside assistance. This may represent a large transient population such as the crew of a fleet of starships, the dwindling remnants of a dying colony, a construction team building a new colony, or an outpost that could evolve into a colony.

World Technology Level (T)

Semso possesses a Technology Level of TL–7.

• Common Communication technologies for this TL include: Early video and early satellite communication networks.
• Common Power Generation technologies for this TL include: Early fuel cells, solar energy, and geothermal power sources.
• Common Transportation technologies for this TL include:
  • Land: Improved automobiles, hovercraft, and bullet trains.
  • Water: Hydrofoils and early triphibians.
  • Air: Hang gliders and supersonic jets.
  • Space: Deep space probes and interplanetary spacecraft (System Craft).

World Government (G)

Semso is governed by Self-Perpetuating Oligarchy. A single family or small group provides the leadership and important positions within the government. These positions are inherited by members of the group or by their relatives. The organization may be a monarchy, with titles passed to family members, or a plutocracy where inheritance of the family fortune includes government position. Alternatively, the organization may be a more typical government apparatus, only with positions of power inherited.

World Law (L)

Semso 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.
