Plemu 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 Zhdierqr Subsector of Fulani 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)[edit]
Plemu is a binary star system.
- The primary is a red main sequence.
- The secondary is a brown dwarf substellar object.

System Data[edit]
The worlds of the system have been surveyed. They consist of:
- The mainworld.
- x5 secondary rocky worlds.
- x2 planetoid belts.
- x2 gas giants.
Mainworld Data[edit]
Plemu 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 prime H region.
- It receives moderate levels of stellar energy.
- The world orbits inside the stars Jump Shadow.
Mainworld Size (S)[edit]
Plemu 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)[edit]
Plemu has a pressure of 0.43 to 0.70 atmospheres. The Thin Atmosphere does not require survival gear although it may be hard on sophonts not accustomed to it.
- 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)[edit]
Plemu has 15-25% of its surface covered by liquid water or ice. There may be a few small seas. Wilderness refueling is possible. Water for the inhabitants needs to be imported and extensively recycled. These worlds are Hell Worlds or Poor Worlds depending on their atmosphere.
- The world has an arid, hostile surface environment.
Mainworld Geography and Topography[edit]
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.
(Placeholder chart, predominantly dry world.)
Native Lifeforms[edit]
No native life: the world has an abiotic oxygen atmosphere.
History & Background (Dossier)[edit]
Plemu is a frontier, a wild and lonely place that rarely sees visitors. Many of the planets and moons within it have ever have had an intelligent being visit them.
- Information about the system is limited.
- The resources of the system are largely untapped.
The system is unpopulated.
- Commercial traffic is extremely rare: the system sees very few visiting ships.
- The star causes interference, strange tones and noises, and heavy static on commo and sensors.
- There are no active navigation beacons.
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.
World Starport (St)[edit]
Plemu does not have a starport. The Class X Starport is an indication that no starport exists in the system. There are no facilities or services available, and no site marked for landing.
