Jump map from Travellermap.com

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

• Its surface is ice-capped with little or no atmosphere and nearly all of its water frozen.
• It is a Non-Aligned world dominated by human sophonts located in the Trichal 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.

Description (Astrography & Planetology)

Bydon has a solitary primary star.

• It is a red main sequence.

Bydon has a solitary primary star.

System Data

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

• The mainworld.
• x2 secondary rocky worlds.
• x1 planetoid belt.
• x3 gas giants.

Mainworld Data

Bydon is tidally locked to its 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.

It orbits towards the outer edge of its star's habitable zone.

• It receives relatively low levels of stellar energy.

Mainworld Size (S)

Bydon 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)

Bydon 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)

Bydon 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 surface of the world is composed of a crust of ice many kilometers thick.
• Much of the surface is cratered and covered in regolith and thick dust of meteoric origin, leaving only around 10% of the icy outer shell exposed.
• Below the outer icy shell there may be a world-ocean of liquid water.

Mainworld Geography and Topography

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

• Locally, detailed maps may be available.

Native Lifeforms

There are possibly sub-ice native lifeforms occupying a variety of ecological niches.

History & Background (Dossier)

Note that social data, though only 40 years old, may be out of date.

• Verified updated data is constantly sought.

World Starport (St)

Bydon has a Class B Starport, a good 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 most kinds of repair, and construction of non-starships. Most ports of this classification have both a Highport and a Downport.

World Demographics (P)

Bydon has a population of 900.

• There are dozens of temporary workers, permitted to stay for a set period, resident on the world.

Urbanization

A single central facility, lying close to the starport, with a few outlying structures and compounds.

• Structures and facilities are sealed against local environmental conditions.
• Almost all of the surface of the world is wilderness.

World Technology Level (T)

Bydon possesses a Technology Level of TL–10 or TL-A in Hexadecimal Notation.

• Common Communication technologies for this TL include: Holovision, Personal Global Communications, and advanced Translators.
• Common Power Generation technologies for this TL include: Increasingly advanced fusion plants and advanced fuel cells.
• Common Transportation technologies for this TL include:
  • Land & Water: Grav belts and maturing gravcraft.
  • Air: Greatly improved hybrid grav-aircraft.
  • Space: Improved interplanetary spacecraft (System Craft).
  • FTL: Jump Drive-1.

World Government (G)

Bydon has no central government or substantial government apparatus; an Anarchy. The largest governmental structure would be a family, tribe, or single clan. The largest group will be between 50 and 100 individuals, and there may be dozens to hundreds of them. This governmental structure can be stable over long periods of time if the population remains small or geographically separated.

World Military

Privately retained security personnel.

World Law (L)

Bydon 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. Body pistols, explosives, and poison gas are typically regulated or prohibited.
