Billow is a barren fluid world with oceans consisting of heavily contaminated water or a substance such as ammonia, methane, hydrocarbons, or other exotic liquid.

• This world has no overt population, government, or law level.
• This world could be populated if anyone had an inclination to do so...
• It is an unclaimed Non-Aligned world located in the Zarn Subsector of Canopus 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.
• This is a "forbidden" world designated as a Red Zone with an environment, laws, customs, life forms, or other conditions that make it extremely dangerous to visitors. Everyone is forbidden to travel here.
• It is a member of the Cassion Strand.

Notes

The two stars of the Billow system have an average separation of 45 AU and orbit a barycenter that lies between them.

• They have an orbital period around one another of approximately 410 standard years.

System Data

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

• The mainworld, orbiting the primary star.
• x7 secondary rocky worlds. Two orbit the primary star, five orbit the secondary star.
• x3 planetoid belts, all orbiting the secondary star.
• x3 small gas giants. Two orbit the primary star, one has a 260 AU / 5,600 year circumbinary orbit in the far outer system.

Mainworld Data

Billow is tidally locked to the system's primary star.

• The star is always high in the sky on the bright face, it hangs on horizon in the twilight zone, while the cold dark face is in permanent darkness.
• The world experiences libration - a regular wobble - as it orbits, causing the star to move in the sky.

Mainworld Size (S)

Billow is a Meso World between 12,000km and 13,500km in diameter. The world has a standard gravity between 0.8G and 1.1G. The horizon will appear about 5.1km away. Vessels with 1G of thrust should check with local starport authorities before attempting to land using emergency power.

Mainworld Atmosphere (A)

Billow has an Insidious Atmosphere which requires the use of a Hostile Environment Suit or Vacc Suit, but extreme conditions cause the corrosive effects to defeat any personal protective measures in a few hours. TL–10 or more advanced survival gear is required to settle this world.

Mainworld Hydrosphere (H)

Billow has 95-100% of its surface covered by a fluid other than water. Wilderness refueling is not possible. Water for the inhabitants needs to be imported and extensively recycled. These worlds may be Hell Worlds.

• This surface fluid may be ammonia, methane, hydrocarbons, or other exotic liquids depending on the local temperature and environment.

Mainworld Geography and Topography

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

(Blank map, exotic world.)

History & Background (Dossier)

Billow is a Forbidden World and is designated as a Red Zone. It presents serious risks and dangers due to the environment or native life forms, laws or customs, or other conditions that make it extremely dangerous to visitors.

• Travel to this world is prohibited.

It is a member of the Cassion Strand, a small cluster and minor trade route lying within the coreward-trailing quadrant of the sector, close to the border with Aldebaran Sector.

Solomani Security keeps a close eye on things to ensure the security of the Confederation and the well-being of its loyal citizens. Almost anyone could be a SolSec informant, passing on all sorts of useful information: some gain a reward or benefit for their actions, others are coerced, but many see it as an act of duty to help protect the Solomani state and its interests.
