Athar is a poor, barren desert-like hellworld with no overt population, government, or law level.

  • This world has no free-standing water.
  • Hellworlds often offer daily, and sometimes hourly, life-threatening situations to their inhabitants.
  • This world could probably be populated by very determined colonists if any had an inclination to do so...
  • It is an unclaimed Non-Aligned world located in the Athar Subsector of Ledge Sector.

Description (Astrography & Planetology)[edit]

The Athar system was officially surveyed by the University of Tal Varisa Deep Sky Program.

  • The results of the survey are available as the DSP Listing, a comprehensive star catalog first published in 5550AD.

System Data[edit]

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

Mainworld Data[edit]

Limited data is available about the body nominated as the mainworld. All of the data has been gathered over centuries of remote observation.

Mainworld Size (S)[edit]

This world 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)[edit]

This world 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 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.

Mainworld Hydrosphere (H)[edit]

This world 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.
