System Data[edit]

Egant-Janna System[edit]

The primary is Egant, a yellow giant star. It has a luminosity of 4.76 Sols, a mass of 2.18 Sols, and a diameter of 4.314 million km. The inner system consists of (II) an exotic atmosphere radworld, (III) a corrosive atmosphere inferno world, and (IV) a very thin atmosphere hospitable world – orbital position (I) is empty. (V) Janna orbits within the habitable zone and is designated the mainworld. (VII) an exotic atmosphere bigworld forms the outer system – orbital position (VI) is empty. Many of the worlds retain satellites.

Mainworld Data[edit]

(V) Janna[edit]

(V) Janna is designated the mainworld. It orbits Egant at a mean distance of 1.47 AU (219.9 million km), within the habitable zone. It has an orbital period of 1 year 76 days and a rotation period of 43 hours. The axial tilt is 16 degrees. Janna has a diameter of 5,877 km, a density of 4.33 g/cm³, and a surface gravity of 0.36 G. The world is geologically active. Its atmosphere is rated as Very Thin, with a mean surface pressure of 0.34 bar and a composition of 79% nitrogen (N2), 19% oxygen (O2), 1% argon (Ar), and 1% xenon (Xe), water vapor (H2O), carbon dioxide (CO2), neon (Ne) and other trace gases. Approximately 12% of the surface is covered in lakes and seas of liquid water: average tidal ranges exceed 0.1m. Mean surface temperature: 48°C. The climate is rated as Hot and experiences minor seasonal changes during the local year. The atmosphere is slow and weak weather systems driven by the star drift across the globe.

Mainworld Geography and Topography[edit]

Total surface area: 109 million km², Land surface area: 96 million km², Water surface area: 13 million km².

Native Lifeforms[edit]

Egant-Janna System[edit]

The hot marginally hospitable world lying in orbital position (IV) (within the H– region of the inner system) has primitive native life, consisting entirely of microscopic cyanobacteria-parallels that exist in any location where they can find even a minimal trace of shelter and moisture. Their metabolic functions maintain the process of atmospheric renewal.

Janna, the mainworld, has extensive native life, consisting of microscopic organisms, stromatolite-parallels and primitive flora that can be found in almost every ecological niche. Their metabolic functions drive the process of atmospheric renewal.

No other world in the system is known to have native life.

History & Background (Dossier)[edit]

World starport[edit]

Janna 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]

Janna possesses a Technology Level of TL–8.

  • Common Communication technologies for this TL include: Fiber optics, improved telephones, and satellite communication and data networks.
  • Common Power Generation technologies for this TL include: Improved geothermal and improved batteries.
  • Common Transportation technologies for this TL include:
    • Land: Advanced automobiles.
    • Water: Triphibians and early artificial gills.
    • Air: Improved helicopters and hypersonic jets.
    • Space: Space shuttles, early space stations, and improved interplanetary spacecraft.

World government[edit]

Janna has a Participatory Democracy government.

  • It is a government by advice and consent of the citizen.
  • The typical power source of this government is an Democracy.
  • The typical power structure of this government is a Unitary State.
