Leware is a low-population fluid world with a population less than 10,000 sophonts in population size.

System Data[edit]

Orchand-Leware System[edit]

The primary is Orchand, an ordinary yellow-white main sequence star. It has a luminosity of 5.34 Sols, a mass of 1.46 Sols and a diameter of 2.115 million km. Orchand's inner system consists of (II) a dense rocky planetoid belt and (IV) a hot small gas giant – orbital positions (I) and (III) are empty. (V) Leware orbits within the habitable zone and is designated the mainworld. (VI) a sparse rocky planetoid belt, (VII) a spectacularly ringed large gas giant, (VIII) a large gas giant, (IX) a small ice giant, and (X) a sparse icy planetoid belt form the outer system. All of the worlds in the system retain satellites.

Harp Subsystem[edit]

The companion is Harp, a magenta-coloured L-type brown dwarf lying approximately 1,800 AU from Orchand. It is not luminous, it has a mass of 0.063 Sols and a diameter of 60,000 km. It retains no planetary bodies.

Mainworld Data[edit]

(IV) Leware[edit]

(IV) Leware is designated the mainworld. It orbits Orchand at a mean distance of 1.74 AU (261 million km), it has an orbital period of 3 years 222 days and a rotation period of 27.3 hours. The axial tilt is 16 degrees. Leware has a diameter of 10,133 km, a density of 6.33 g/cm³, and a surface gravity of 0.91 G. The world is geologically active. Its atmosphere is rated as Insidious, with a mean surface pressure of 35.5 bar and a composition of 93% carbon dioxide (CO2), 5% nitrogen (N2), 1% water vapor (H2O), and 1% argon (Ar), muriatic acid vapor (HCl), sulfur dioxide (SO2), carbon monoxide (CO) and other trace gases. Approximately 27% of the surface is covered in shallow seas of superheated water, kept liquid by the immense atmospheric pressure which increases its boiling point to 243°C: average tidal ranges are around 0.6m. The waters contain many chemicals in solution. Mean surface temperature: 197°C. The atmosphere is dynamic and powerful weather systems, driven by the star and the seas, sweep across the globe. The climate is seasonal.

Satellites:[edit]

Leware retains one natural satellite, a cratered vacuum worldlet named Chum:

(IVa) Chum (UWP H300000-0, orbiting at 25 Diameters/250,000 km).

Mainworld Geography and Topography[edit]

Total surface area: 323 million km², Land surface area: 236 million km², Fluid surface area: 87 million km².

Native Lifeforms[edit]

Despite the extremely hostile conditions Leware has primitive native life, consisting entirely of microscopic cyanobacteria-parallels that exist in any location where they can find conditions that meet their biological needs. Their metabolic functions play little part in the process of atmospheric renewal.

History & Background (Dossier)[edit]

World starport[edit]

Leware has a poor quality starport.

  • A Class-D Starport Facility has minimal if any shipyards and can only perform extremely limited repair work.
  • This facility has many skilled personnel who can perform minor repair work.
  • This facility has refueling infrastructure and limited refining capabilities. One may purchase unrefined fuel here.
  • Starports of this class very rarely have both a Lowport and a Highport.

World technology level[edit]

Leware possesses a Technology Level of TL–7.

  • Common Communication technologies for this TL include: Early video and early satellite communication networks.
  • Common Power Generation technologies for this TL include: Early fuel cells, solar energy, and geothermal power sources.
  • Common Transportation technologies for this TL include:
    • Land: Improved automobiles, hovercraft, and bullet trains.
    • Water: Hydrofoils and early triphibians.
    • Air: Hang gliders and supersonic jets.
    • Space: Deep space probes and interplanetary spacecraft.

World government[edit]

Leware has no well-defined government structure.

  • In many cases, tribal, clan or family bonds predominate.
  • The typical power source of this government is an Pantocracy or Chaos.
  • The typical power structure of this government is a Confederation (Anarchy).
