System Data[edit]

Dzarah-Xenus System[edit]

The primary is Dzarah, an ordinary yellow main sequence star. It has a luminosity of 0.994 Sols, a mass of 1 Sol, and a diameter of 1.366 million km. The inner system consists of (I) a trace atmosphere inner world, (II) a corrosive atmosphere inferno world, and (III) an exotic atmosphere stormworld. (IV) Xenus orbits within the habitable zone and is designated the mainworld. (V) an exotic atmosphere bigworld, (VI-I) a large gas giant, (VI-II) a sparse stony planetoid belt, (VII) a ringed large gas giant, (VIII) a dense icy planetoid belt, (IX-I) a small gas giant, and (IX-II) a small ice giant form the outer system. Many of the worlds retain satellites.

Mainworld Data[edit]

(IV) Xenus[edit]

(IV) Xenus is designated the mainworld. It orbits Dzarah at a mean distance of 0.98 AU (146.6 million km), within the habitable zone. It has an orbital period of 354 days 8 hours and a rotation period of 31 hours. The axial tilt is 32 degrees. Xenus has a diameter of 11,728 km, a density of 3.78 g/cm³, and a surface gravity of 0.63 G. The world is geologically active. Its atmosphere is rated as Dense, Tainted, with a mean surface pressure of 1.91 bar and a composition of 79% nitrogen (N2), 19% oxygen (O2), 1% argon (Ar), and 1% carbon dioxide (CO2), water vapor (H2O), ozone (O3), neon (Ne) and other trace gases. The taint is caused by allergenic spores and pollens of organic origin. Approximately 37% of the surface is covered in seas of liquid water: average tidal ranges exceed 0.2m. Mean surface temperature: 19°C. The climate is rated as Temperate-Prime and experiences minor seasonal changes during the local year. The atmosphere is dynamic and strong weather systems driven by the star and the seas work across the globe.


Xenus retains a single natural satellite, a very thin atmosphere worldlet named Korith:

(IVa) Korith (UWP Y322000-0, orbiting at 45 Diameters/525,000 km)

Mainworld Geography and Topography[edit]

Total surface area: 432 million km², Land surface area: 272 million km², Water surface area: 160 million km².

Native Lifeforms[edit]

Dzarah-Xenus System[edit]

Xenus, the mainworld, has extensive, abundant native life, with complex organisms inhabiting every ecological niche. Their metabolic functions drive the process of atmospheric renewal.

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

World starport[edit]

Xenus 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]

Xenus possesses a Technology Level of TL–4.

World government[edit]

Xenus 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.
