Luasyeh is a poor, 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 Ekthkawa Subsector of Harea 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 hot world, with a climate of high temperatures.
• It lies within the Great Rift.

System Data

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

• The mainworld.
• x3 secondary rocky worlds.
• x2 planetoid belts.
• x1 gas giant.

Mainworld Data

Luasyeh 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 at the inner edge of the habitable zone.

• It receives high levels of stellar energy.

Mainworld Size (S)

Luasyeh is a Meso World between 5,600km and 7,200km in diameter. The world has low gravity between 0.32G and 0.46G. The horizon will appear about 3.6km away.

Mainworld Atmosphere (A)

Luasyeh 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 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.

• It experiences high temperatures within the twilight zone.

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 percentage of oxygen in the atmosphere varies according to the density of global cloud cover.

Mainworld Hydrosphere (H)

Luasyeh has 25-35% of its surface covered by liquid water. It has a few small seas. Wilderness refueling is possible. Water for the inhabitants will be recycled.

• The warm stormy seas are shrouded in fogs, steams, and hazes.

Mainworld Geography and Topography

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

• Locally, detailed maps may be available.

(Placeholder chart, predominantly dry world.)

Native Lifeforms

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

History & Background (Dossier)

Luasyeh is a wilderness, a wild and lonely place that almost never sees visitors. Many of the planets and moons within the system have never had an intelligent being visit them.

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.
