Demar is a pre-agricultural, moderate population rich garden world with over a hundred million, but not yet at a billion sophonts in population size.

  • Garden worlds are known for their near-ideal utopian environments conducive to most sophonts, plants, animals, and other forms of life.
  • It is a pre-agricultural world with an environment suitable for large scale agricultural and livestock industries that have not yet been widely developed.
  • This is a rich world with a prosperous and thriving world economy.
  • Its economy and population are rapidly growing and living conditions are expected to quickly rise barring outside forces.
  • It is a Non-Aligned world dominated by human sophonts located in the Veesene Subsector of Halcyon Sector.

System Data[edit]

Chaster-Demar System[edit]

The primary is Chaster, an ordinary yellow main sequence star. It has a luminosity of 0.778 Sols, a mass of 0.96 Sols, and a diameter of 1.299 million km. The inner system consists of (I) a trace atmosphere inner world, and (II) a standard atmosphere hospitable world. (III) Demar orbits within the habitable zone and is designated the mainworld. (IV) a thin atmosphere hospitable world forms the inner part of the outer system. Orbital positions (V) through (X) are unavailable due to the presence of the companion star. (XI) a sparse stony planetoid belt, (XII) a small gas giant, (XIII) a ringed large gas giant, and (XIV) a small ice giant form the outer part of the outer system. Many of the worlds retain satellites.

Aaron Subsystem[edit]

The companion is Aaron, a red subdwarf star that orbits Chaster at 11.3 AU (orbital position (VIII), 1.69 billion km) and has an orbital period of 38 years 281 days. It has a luminosity of 0.0074 Sols, a mass of 0.134 Sols, and a diameter of 212,000 km. (I) a vacuum worldlet, (II) a trace atmosphere iceworld, (III) an exotic atmosphere bigworld, and (IV) a vacuum iceworld form the outer system. Many of the worlds retain satellites.

Mainworld Data[edit]

(III) Demar[edit]

(III) Demar is designated the mainworld. It orbits Chaster at a mean distance of 0.68 AU (101.7 million km), within the habitable zone. It has an orbital period of 209 days 1 hour and a rotation period of 23 hours. The axial tilt is 12 degrees. Demar has a diameter of 9,312 km, a density of 5.38 g/cm³, and a surface gravity of 0.71 G. The world is geologically active. Its atmosphere is rated as Standard, with a mean surface pressure of 0.79 bar and a composition of 78% nitrogen, 21% oxygen, and 1% argon, water vapour, carbon dioxide, neon and other trace gases. Approximately 64% of the surface is covered in oceans of liquid water: average tidal ranges exceed 0.2m. Mean surface temperature: 22°C. The atmosphere is active and strong weather systems driven by the star and the oceans sweep across the globe. The climate is seasonal.

Satellites[edit]

Demar retains two natural satellites, a trace atmosphere worldlet named Merott and a vacuum worldlet named Faldan:

(IIIa) Merott (UWP Y110000-0, orbiting at 11 Diameters/102,000 km)
(IIIb) Faldan (UWP Y200000-0, orbiting at 35 Diameters/326,000 km)

Mainworld geography and topography[edit]

Total surface area: 272 million km², Water surface area: 174 million km², Land surface area: 98 million km².

Native lifeforms[edit]

Demar has extensive native life. Their metabolic functions power the process of atmospheric renewal.

History & Background (Dossier)[edit]

World starport[edit]

Demar has a routine quality starport.

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

World technology level[edit]

Demar possesses a Technology Level of TL–6.

World government[edit]

Demar has a Balkanized Government.

  • No central ruling authority exists. Rival governments compete for control.
  • The typical power source of this government is a Balkanization.
  • The typical power structure of this government is a Confederation (Anarchy).
