Barsoom is a high-population world with a billion or more sophonts in population size.

  • This world has a nearby Naval Base, usually associated with military starships.
  • This world has a nearby Military Base, usually associated with military ground forces.
  • This world has a colony at Arisia (world).

Description / Astrography & Planetology[edit]

The Barsoom primary is small, older star, with only the mainworld in its habitable zone.

System Data[edit]

The Barsoom primary is a M1 spectral class star; a smaller, older star than most in this region. It has a habitable zone of 0.14 AU and 0.24 AU.

This system has 2 gas giants, making it viable refueling point.

There are 7 rocky worlds, with Barsoom being the largest and closest body.

  • 0.20 AU Barsoom

Mainworld Data[edit]

Barsoom is a standard rocky planet, with a metallic core, and a planetary day of 14.0 standard hours. This configuration provides a stronger than normal magnetic field, allowing for life to survive in such close propinquity to its primary. The high spinrate and increased radius of Barsoom also reduces the effective gravity at the surface.

Barsoom is a planetary oddity: a small world with a thin oxygen-nitrogen atmosphere and a significant amount of water. Although close to its red dwarf sun, it is not tide-locked and has two small moons. which appear to be captured planetoids -- though no planetoid belt exists in the system. These anomalies have fueled speculation about planetary engineering performed by a pre-Humaniti civilization.

Mainworld Geography & Topography[edit]

Barsoom appears to be a old world with little tectonic activity. There are several mountain ranges, but most are of moderate altitude or lower. There are 3 large seas distributed across the surface.

The planetary ecology is described as quite fragile, and the population takes threats to its well-being seriously as part of planetary policy.

Recently the government has taken independent action against the pirates who plague the subsector.

History & Background (Dossier)[edit]

Barsoom is an important, high-population world with two small moons, located in Jardin Subsector of the Solomani Rim.

World Starport[edit]

Barsoom has a Class A Starport, an excellent 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 other kinds of repair, and construction of both starships and non-starships. Most ports of this classification have both a Highport and a Downport.

Barsoom maintains 2 separate, fully-functional Highports.

  • Barsoom Freeport
  • Barsoom BurroughsPort

This arrangement was chosen to maximize flexibility and goods throughput, though the Barsoom military must appreciate the lack of a blindside in their operations. That said, access to the surface by non-local spacecraft is expressly forbidden without prior approval and military escort. They are quite serious, and visitors should expect interceptor spacecraft and aircraft to immediately engage their craft should it begin descent.

Otherwise, visitors can find an approved Barsoom descent transport (BDT) with relative ease.

There are at least 4 Downports available located near regional capitols or manufacturing centers. These downports offer clean accommodations, restaurants, banking, chandlers, business offices, etc. Security is considered higher than most worlds, and activities of visitors are tracked and monitored. A regional passport can be applied for and acquired by most visitors that will allow access to the local city area near the downport. Expanded access passports can be acquired after a person has spent at least 30 standard days on Barsoom or its highports. Keep in mind that passport access is quite granular, and access to specific locations can be granted within the hour or revoked without warning.

The Travellers' Aid society maintains a hostel here, and may be able to advise Travellers on planning access.

World Technology Level[edit]

Barsoom possesses a Technology Level of TL–13 or TL-D in Hexadecimal Notation.

  • Common Communication technologies for this TL include: Holovideo recorders.
  • Common Power Generation technologies for this TL include: Miniature super-batteries, prototype collectors, advanced fusion plants.
  • Common Transportation technologies for this TL include:

World Government[edit]

Barsoom is governed by an Impersonal Bureaucracy. The leadership of the government is another form (democracy, dictatorship, oligarchy), but the bureaucracy dictates government policy and its execution. Government leadership is reduced to little more than figureheads and does not select the bureaucracy leadership or its members.

World Law Level[edit]

Scout Survey has assigned Law Level B, with rigid government-imposed limitations on civilian movements. In most locations, these limits are largely reasonable, allowing for a normal standard of living and business activities. Limits become more controlling around any region or activity that touches on the environment or ecostructures.

World Military[edit]

Recently the government has taken independent action against the pirates who plague the subsector.

World Economy[edit]

The Barsoom economies are many and varied, and focus on local demand. Due to the fragility of the local ecosystems, Barsoom imports large amounts of food stuffs from its neighbor, Gladstone_(world).

Trade Data[edit]

Metals, manufactured goods, computers, electronics, heavy equipment.

World Demographics[edit]

Humaniti 100%

World Culture[edit]

"The world moves quickly, but we move with care."

This world is prosperous, producing valued products efficiently using the latest technologies. Its people work hard, but have a continuous lifestyle that deliberately ignores the position of the Sun.

Public Education, including advanced degrees, are free. As a result, a significant portion of the population is always continuing its education. Engineering and Science research is always ongoing.


Cities are more or less evenly spread over the surface, following resource centers.
