System Data[edit]

This star system is detailed using the Fringian Variant System Description.

Furey System[edit]

The primary is Furey, an red subgiant star. It has a luminosity of 0.04 Sols, a mass of 0.489 Sols, and a diameter of 764,000 km. (I) a sparse stony planetoid belt, (III) a sparse stony planetoid belt, (IV) a trace atmosphere inner world, (V) a corrosive atmosphere inferno world – orbital position (II) is empty. (VI) a corrosive atmosphere inferno world orbits within the habitable zone. (VII) a corrosive atmosphere inferno world, and (VIII) a thin atmosphere radworld form the outer system. The outer worlds retain satellites.


The companion is Anega, an ordinary red main sequence star. It has a luminosity of 0.04 Sols, a mass of 0.489 Sols, and a diameter of 764,000 km. (I) Irat orbits within the habitable zone and is designated the mainworld. (II) an exotic atmosphere bigworld, (III) a small gas giant, (IV) a large gas giant, (V) a very thin atmosphere radworld, and (VI) a ringed small ice giant form the outer system. Most of the worlds retain satellites.

Mainworld Data[edit]

(I) Irat[edit]

(I) Irat is designated the mainworld. It orbits Anega at a mean distance of 0.16 AU (23.9 million km), within the habitable zone. It has an orbital period of 33 days 10 hours: it is tidally locked to Anega. The axial tilt is 7 degrees. Irat has a diameter of 10,576 km, a density of 4.79 g/cm³, and a surface gravity of 0.72 G. The world is flexed by tidal forces and is geologically active. Its atmosphere is rated as Thin, Tainted, with a mean surface pressure of 0.46 bar and a composition of 78% nitrogen, 20% oxygen, and 1% argon, water vapour, neon and other trace gases. The atmospheric taint is caused by gases of volcanic origin, principally carbon dioxide, sulfur dioxide, and carbon monoxide in high enough concentrations to present a hazard to health. Approximately 77% of the surface is covered in oceans of liquid water: average tidal ranges exceed 0.75m. Mean surface temperature: 33°C. The atmosphere is dynamic and strong weather systems driven by the star and the oceans sweep across the globe. The climate is static.

Mainworld geography and topography[edit]

Total surface area: 351 million km², Water surface area: 270 million km², Land surface area: 81 million km².

Native lifeforms[edit]

Irat has extensive native life. Their metabolic functions drive the process of atmospheric renewal.

History & Background (Dossier)[edit]

World starport[edit]

Irat 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]

Irat possesses a Technology Level of TL–5.

World government[edit]

Irat has a Feudal Technocracy government.

  • It is a government by specific individuals for those who agree to be ruled. Relationships are based on the performance of technical activities which are mutually-beneficial.
  • The typical power source of this government is an Oligarchy.
  • The typical power structure of this government is a Hegemony.
