System Data[edit]

Garada-Viller System[edit]

The primary is Garada, an ordinary white main sequence star. It has a luminosity of 7.18 Sols, a mass of 1.62 Sols, and a diameter of 2.282 million km. The inner system consists of (I) a vacuum worldlet, (III) a trace atmosphere inner world, (IV) a corrosive atmosphere inferno world, and (V) a thin atmosphere hospitable world – orbital position (II) is empty. (VI-I) Viller, designated the mainworld, and (VI-II) a sparse stony planetoid belt have a shared orbit within the habitable zone. (VII-I) a ringed large gas giant, and (VII-II) a large gas giant form the outer system. Many of the worlds retain satellites.

Semeto Subsystem[edit]

The companion is Semeto, a dim red subdwarf star that orbits Garada at a mean distance of 322 AU (orbital position (XIII), 48.2 billion km) and has an orbital period of 4,540 years. It has a luminosity of 0.00152 Sols, a mass of 0.093 Sols, and a diameter of 127,000 km. (I) a trace atmosphere radworld, (II) an exotic atmosphere bigworld, (III) a sparse icy planetoid belt, and (IV) a small gas giant form the outer system. Many of the worlds retain satellites.

Mainworld Data[edit]

(VI-I) Viller[edit]

(VI-I) Viller is designated the mainworld. It orbits Garada at a mean distance of 2.32 AU (347.1 million km), within the habitable zone. It has an orbital period of 2 years 284 days and a rotation period of 35 hours. The axial tilt is 14 degrees. Viller has a diameter of 11,504 km, a density of 3.73 g/cm³, and a surface gravity of 0.61 G. The world is geologically active. Its atmosphere is rated as Dense, Tainted, with a mean surface pressure of 1.69 bar and a composition of 75% nitrogen (N2), 22% oxygen (O2), 2% argon (Ar), 1% xenon (Xe), and 1% water vapor (H2O), carbon dioxide (CO2), ozone (O3), carbon monoxide (CO), neon (Ne) and other trace gases. The taint is caused by the high percentage of inert gases, principally argon and xenon. Approximately 64% of the surface is covered in seas of liquid water: average tidal ranges exceed 0.4m. Mean surface temperature: 42°C. The climate is rated as Hot and experiences minor seasonal changes during the local year. The atmosphere is very active and powerful weather systems driven by the star and the oceans surge across the globe.


Viller retains two natural satellites, a cratered vacuum worldlet named Rylan and a thin atmosphere hospitable world named Kala:

(VI-Ia) Rylan (UWP H200000-0, orbiting at 12 Diameters/140,000 km)
(VI-Ib) Kala (UWP G443000-0, orbiting at 60 Diameters/690,000 km)

Mainworld Geography and Topography[edit]

Total surface area: 416 million km², Water surface area: 266 million km², Land surface area: 150 million km².

Native Lifeforms[edit]

Garada-Viller System[edit]

The hot marginally hospitable world lying in orbital position (V) (within the H– region of the inner system) has extensive native life, consisting of minute multicellular organisms that can be found in most ecological niches. Their metabolic functions drive the process of atmospheric renewal.

Viller, the mainworld, has extensive, abundant native life, with complex organisms inhabiting every ecological niche. Their metabolic functions drive the process of atmospheric renewal. Fauna follows a wide variety of body patterns but the prevalent form is Asymetrical N-TBS-AL-LL-N, with an exoskeleton, ichor fluids and a leathery exterior. Most native organisms are indigestible by humans and many are toxic.

  • Kala, Viller's temperate hospitable outer moon 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]

Viller is a member of the Protectorate of Leset.

World starport[edit]

Viller 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]

Viller possesses a Technology Level of TL–6.

World government[edit]

Viller 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.
