Isigo is a barren world with 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 Bablari Subsector of Iphigenaia 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)

Isigo is a binary star system.

• The primary is a red main sequence.
• The secondary is a tiny white dwarf stellar remnant.

The system lies deep within the Great Rift.

The system is part of the Splinters.

System Data

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

• The mainworld.
• x3 secondary rocky worlds.
• x4 gas giants.

Mainworld Data

Isigo 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 zones colder outer H- region.
• It receives lower levels of stellar energy.

• The world orbits inside the stars Jump Shadow.

Mainworld Size (S)

Isigo is a Small World between 4,000km and 5,600km in diameter. The world has low gravity between 0.24G and 0.34G. The horizon will appear about 3km away.

Mainworld Atmosphere (A)

Isigo has a pressure of 0.10 to 0.42 atmospheres. The very thin pressures require a respirator or Oxygen Mask 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 Respirator Combination Mask. Some taints may require more protective equipment. TL–5 or more advanced survival gear is required to settle this world.

• The world has an abiotic oxygen atmosphere.
• Oxygen is produced by photocatalytic conversion of surface materials by stellar energy.
• Fresh surface material is constantly exposed through processes such as seismic activity, volcanism, or erosion.
• The oxygen rapidly depletes from the atmosphere through oxidization with surface materials: a rough equilibrium between production and depletion exists.
• The world has a low oxygen taint: the percentage of oxygen in the atmosphere varies according to the density of global cloud cover.

Mainworld Hydrosphere (H)

Isigo has 35-45% of its surface covered by liquid water. There will be a number of small seas or one larger body of water. Wilderness refueling is possible.

• The world experiences low temperatures.
• Much of the surface is a frigid, hostile environment.

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.

Native Lifeforms

No native life: the world has an abiotic oxygen atmosphere.

History & Background (Dossier)

Isigo is an empty and untamed wilderness. Very few intelligent beings have ever have set foot on any of the worlds in the system.

• Information about the system is limited.
• The resources of the system remain untapped.

Officially, the system almost never sees traffic.

• Commo typically only picks up natural background noise and static.

The Aslan appear to be using the system as a link in a secretive path across the region.

• If they are, their vessels only enter the system very occasionally.
• They likely conduct refueling operations then continue on their way.

Aslan Clan interests may have established an exploration route, seeking to find a safe course into the empty systems of Theron Sector.

• They seem to be moving along the very edge of the Great Rift, using isolated systems and a hidden fuel cache.
  • The most likely location for any such fuel cache is considered to be hex 2901 of Waoasi Subsector (Subsector D of Faoheiroi'iyhao Sector).
• If it really exists, the route relies on Jump-5 vessels.

The Clans would likely use any such route to communicate with and supply their explorers, pioneers, and scattered outposts within the region.

• The existence of the route and the fuel cache have not been proven.

(Chart sourced from Traveller Map)

• Rift regions are shown in blue.
• Known Aslan outposts and settlements are ringed in red.

Note that social data, though only 40 years old, may be out of date: previously undocumented groups may now inhabit the system and maintain their own culture, forms of government, and systems of law.

• Verified updated data is constantly sought.
