Orowan is a non-agricultural, pre-industrial vacuum world, which warrants hazardous environment precautions.

  • Life in a vacuum requires great discipline. After all, it only takes one forgotten seal on a vacuum suit to spell death. Those who survive tend to be very methodically-minded and attentive to small detail.
  • It is unable to produce quality foodstuffs and must import them.
  • It requires extensive imports of outside technology to maintain a modern, star-faring society. The need to import most manufactured and high technology goods drives the price of these goods up in the open market.
  • Its economy and population are slowly growing and living conditions are expected to improve in the near future barring outside forces.
  • It is a Non-Aligned world dominated by human sophonts located in the Orowan Subsector of Halcyon Sector.
  • This world-system hosts a Military Base, usually associated with military ground forces, which may be located on or off-world.

System Data[edit]

Amadur-Orowan System[edit]

The primary is Amadur, a gigantic orange bright giant star. It has a luminosity of 2138 Sols, a mass of 13.4 Sols and a diameter of 153 million km – the corona extends as far as 1.02 AU, to orbital position (IV). The inner system consists of (IV) an extremely hot large gas giant orbiting close to the surface of the star, (VIII) a sparse stony planetoid belt, and (IX) a vacuum inner world – orbital positions (V), (VI) and (VII) are empty. (X) Perrin, a small gas giant, orbits within the habitable zone; (Xb) Orowan is its outer moon and is designated the mainworld. (XI) a small gas giant, (XII) an exotic atmosphere bigworld, (XIII-I) a vacuum worldlet, and (XIII-II) a vacuum iceworld form the outer system. Many of the worlds retain satellites.

(X) Perrin[edit]

(X) Perrin is a small gas giant that orbits Amadur at a mean distance of 37.6 AU (orbital position (X), 5.62 billion km), within the habitable zone, and has an orbital period of 63 years. It has a diameter of 39,000 km and is a heavily banded reddish-brown colour. It retains a family of two major satellites of which the outer, (Xb) Orowan, is designated the mainworld.

Mainworld Data[edit]

(Xb) Orowan[edit]

(Xb) Orowan is the outer of the two major moons of (X) Perrin and is designated the mainworld. Orowan orbits its parent world at a mean distance of 30 diameters (1.18 million km), with an orbital period of 6 days 9 hours and a rotation period of 6 days 9 hours: Orowan is tidally locked to Perrin. It has an axial tilt of 3 degrees. Orowan has a diameter of 4,643 km, a density of 4.43 g/cm³ and a surface gravity of 0.29 G. Tidal stresses caused by the gravitational pull of Perrin cause occasional geological activity. The atmosphere is rated as Vacuum. It has no hydrosphere. Mean surface temperature: 170°C in sunlight, -10°C in shadow.

Mainworld geography and topography[edit]

Total surface area: 68 million km².

Native lifeforms[edit]

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

World starport[edit]

Orowan has a good quality starport.

  • A Class-B Starport Facility has not very well developed shipyards and is only capable of producing spaceships.
  • This facility has many very skilled personnel who can perform not only major repair work, but overhaul work as well.
  • This facility has advanced refueling and refining infrastructure. One may purchase practically any kind of refined fuel here.
  • Almost every starport of this class possesses both a Lowport and a Highport. Such ports rarely have more than one of each kind of port.

World technology level[edit]

Orowan possesses a Technology Level of TL–11 or TL-B in Hexadecimal Notation.

World government[edit]

Orowan has a Representative Democracy government.

  • It is a government by elected representatives.
  • The typical power source of this government is a Republic.
  • The typical power structure of this government is a Unitary State .
