Jump map from Travellermap.com

Yarsa is a low-population vacuum world, with a population of less than 10,000 sophonts, warranting hazardous environment precautions.

• Life in a vacuum requires great discipline. After all, it only takes one forgotten seal on a vacuum suit to spell death. Those who survive tend to be very methodically-minded and attentive to small detail.
• It is a Non-Aligned world dominated by human sophonts located in the Tangal 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.

System Data

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

• The mainworld.
• x4 secondary rocky worlds.
• x1 planetoid belt.

Mainworld Data

Yarsa is a Twilight Zone World.

• One side of the world permanently faces towards the star and one side permanently faces away.
• In the narrow region between permanent night and permanent day, the primary star eternally hangs on the horizon.

The mainworld orbits within the star's Habitable Zone.

• It lies within the zone's colder outer H- region.
• It receives relatively low levels of stellar energy.

Mainworld Size (S)

Yarsa 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)

Yarsa has a pressure of less than 0.001 atmospheres which requires the use of a Vacc Suit. TL–8 or more advanced survival gear is required to settle this world.

• Vacuum worlds have no climate, but experience extreme differences in temperature between direct starlight and shade.

Mainworld Hydrosphere (H)

Yarsa has no free-standing water or ice on the surface. Wilderness refueling isn't possible on this world. Water for the inhabitants needs to be imported and extensively recycled. These worlds are classified Desert World or a Hell World depending on their atmosphere.

Mainworld Geography and Topography

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

• Locally, detailed maps may be available.
• Verified updated charts are constantly sought.
• Detailed survey data commands premium prices.

History & Background (Dossier)

No information yet available.

World Starport

Yarsa 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 Technology Level

Yarsa possesses a Technology Level of TL–9.

• Common Communication technologies for this TL include: Fiber optics and satellite communication and data networks.
• Common Power Generation technologies for this TL include: Early fusion power.
• Common Transportation technologies for this TL include:
  • Land: Ultra high-speed trains and early grav vehicles.
  • Water: High efficiency sailcraft, multihulled seacraft, improved artificial gills.
  • Air: Tiltrotorcraft, exotic VTOL's, PARWIG, and rocket-assisted suborbitals.
  • Space: SSTO spacecraft, early military spacecraft (System Craft), and interstellar STL starships
  • FTL: Prototype Jump Drive-1.

World Government

Yarsa 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.
