Deevan is an agricultural, nonindustrial, pre-rich garden world with a near-ideal, utopian environment conducive to most sophonts, but still lacks an adequate population to expand its economy to a rich status.

  • As an agricultural world, this world is a near-ideal environment for producing quality foodstuffs of plant, animal, and other forms. Quality foodstuffs are a major export commodity for this world.
  • It requires extensive imports of outside technology to maintain a modern, star-faring society. Having to import most manufactured and high tech goods drives the price up for these items at this world.
  • Its economy and population are rapidly growing and living conditions are expected to quickly rise barring outside forces.
  • This a "low technology" world with technology competency well below technology standards for Charted Space.
  • It is a Non-Aligned world dominated by human sophonts located in the Esser Subsector of Divide Sector.

System Data[edit]

Angala-Deevan System[edit]

The primary is Angala, an ordinary yellow main sequence star. It has a luminosity of 0.52 Sols, a mass of 0.871 Sols, and a diameter of 1.264 million km. The inner system consists of (I) a corrosive atmosphere inferno world, (II) a very thin atmosphere hospitable world, (III) Deevan orbits within the habitable zone and is designated the mainworld. (IV) a very thin atmosphere hospitable world, (V) a large gas giant, (VI-I) a ringed large gas giant, and (VI-II) form the outer system. Many of the worlds retain satellites.

Bardo Subsystem[edit]

The companion is Bardo, a dim red main sequence star that lies at a mean distance of 589 AU (orbital position (XIV), 88.1 billion km) from Angala. It has a luminosity of 0.0055 Sols, a mass of 0.302 Sols, and a diameter of 444,000 km. (I) a trace atmosphere worldlet, (II) a vacuum iceworld, (III) a large gas giant, (IV) a small gas giant, and (V) a vacuum iceworld form the outer system. Many of the worlds retain satellites.

Ginty Subsystem[edit]

The far companion is Ginty, a dim red subdwarf star that orbits Bardo at a mean distance of 20.2 AU (orbital position (IX), 3.02 billion km) and has an orbital period of 165 years. It has a luminosity of 0.00152 Sols, a mass of 0.093 Sols, and a diameter of 127,000 km. (I) a sparse stony planetoid belt, (II) an exotic atmosphere bigworld, and (III) a trace atmosphere iceworld form the outer system. Many of the worlds retain satellites.

Mainworld Data[edit]

(III) Deevan[edit]

(III) Deevan is designated the mainworld. It orbits Angala at a mean distance of 0.65 AU (97.2 million km), within the habitable zone. It has an orbital period of 205 days 2 hours and a rotation period of 33 hours. The axial tilt is 25 degrees. Deevan has a diameter of 11,552 km, a density of 4.83 g/cm³, and a surface gravity of 0.79 G. The world is geologically active. Its atmosphere is rated as Dense, with a mean surface pressure of 1.73 bar and a composition of 77% nitrogen (N2), 21% oxygen (O2), 1% argon (Ar), and 1% water vapor (H2O), carbon dioxide (CO2), ozone (O3), neon (Ne) and other trace gases. Approximately 61% of the surface is covered in oceans of liquid water: average tidal ranges exceed 0.35m. Mean surface temperature: 19°C. The climate is rated as Temperate-Prime and experiences moderate seasonal changes during the local year. The atmosphere is active and strong weather systems driven by the star and the oceans sweep across the globe.

Satellites[edit]

Deevan retains two natural satellites, a vacuum worldlet named Pestens and a trace atmosphere worldlet named Kuris:

(IIIa) Pestens (UWP Y100000-0, orbiting at 15 Diameters/105,000 km)
(IIIb) Kuris (UWP Y310000-0, orbiting at 25 Diameters/290,000 km)

Mainworld Geography and Topography[edit]

Total surface area: 419 million km², Water surface area: 256 million km², Land surface area: 163 million km².

Native Lifeforms[edit]

Angala-Deevan System[edit]

The hot marginally hospitable world lying in orbital position (II) (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.

Deevan, 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.

The cold marginally hospitable world lying in orbital position (IV) (within the H+ region of the outer system) has primitive cryophile native life, consisting entirely of microscopic cyanobacteria-parallels that thrive in the harsh conditions. Their metabolic functions drive the process of atmospheric renewal.

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

Bardo Subsystem[edit]

The small gas giant lying in orbital position (IV) (within the outer system) has jovionoid lifeforms within its atmosphere.

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

Ginty Subsystem[edit]

No world in the subsystem is known to have native life.

History & Background (Dossier)[edit]

No information yet available.

World starport[edit]

Deevan 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]

Deevan possesses a Technology Level of TL–5.

  • Common Communication technologies for this TL include: Telephone, radio, and television.
  • Common Power Generation technologies for this TL include: Electricity, hydrocarbon internal combustion, and the most fundamental atomic energy.
  • Common Transportation technologies for this TL include:
    • Land: Ground cars or automobiles and tracked vehicles.
    • Water: Large ships and submersibles with steel hulls.
    • Air: Early aircraft including seaplanes and very early unmanned rockets.

World government[edit]

Deevan has a Civil Service Bureaucracy government.

  • It is a government by agencies employing individuals selected for their expertise.
  • The typical power source of this government is an Oligarchy.
  • The typical power structure of this government is a Unitary State.
