Anarides is a low population, fluidic hellworld of less than 10,000 sophonts struggling to survive in a inhospitable environment.

  • A fluid world has an oceanic geography of a liquid other than water such as ammonia, methane, hydrocarbons, or other exotic liquids.
  • Hellworlds often offer daily, and sometimes hourly, life-threatening situations to their inhabitants.
  • It is a Non-Aligned world dominated by human sophonts located in the Brink Subsector of Shadow Rift Sector.

System Data[edit]

Nilson-Anarides System[edit]

The primary is Nilson, 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, (II) an exotic atmosphere stormworld, (III-I) a vacuum worldlet, (III-II) a trace atmosphere inner world, (IV) a corrosive atmosphere inferno world, (V) an exotic atmosphere radworld, (VI) Anarides orbits within the habitable zone and is designated the mainworld. (VII) an exotic atmosphere bigworld, (VIII-I) a dense rocky planetoid belt, and (VIII-II) a very large gas giant form the outer system. Many of the worlds retain satellites.

Mainworld Data[edit]

(VI) Anarides[edit]

(VI) Anarides is designated the mainworld. It orbits Nilson at a mean distance of 3.04 AU (454.8 million km), within the habitable zone. It has an orbital period of 4 years 60 days and a rotation period of 33 hours. The axial tilt is 4 degrees. Anarides has a diameter of 12,944 km, a density of 5.74 g/cm³, and a surface gravity of 1.05 G. The world is geologically active. Its atmosphere is rated as Corrosive, with a mean surface pressure of 38.4 bar and a composition of 91% nitrogen (N2), 6% carbon dioxide (CO2), 2% azane (NH3), and 1% argon (Ar), chlorine (Cl), methane (CH4), nitrogen dioxide (NO2), carbon monoxide (CO), abiotic oxygen (O2), neon (Ne) and other trace gases. Approximately 17% of the surface is covered in lakes and seas of ammonium hydroxide (NH4OH), ammonium chloride (NH4Cl), and liquid ammonia (NH3): average tidal ranges exceed 0.1m. Mean surface temperature: -35°C. The climate is rated as Cold and is static, with no seasonal changes during the local year. The atmosphere is very active and powerful weather systems driven by the star sweep across the globe.


Anarides retains a single natural satellite, an ice-capped vacuum worldlet called Garafan:

(VIa) Garafan (UWP Y201000-0, orbiting at 25 Diameters/325,000 km)

Mainworld Geography and Topography[edit]

Total surface area: 526 million km², Land surface area: 437 million km², Fluid surface area: 89 million km².

Native Lifeforms[edit]

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

History & Background (Dossier)[edit]

No information yet available.

World starport[edit]

Anarides has a Class D Starport, a poor quality installation which has few of the expected amenities. There is unrefined fuel for starships and a limited variety of ship provisions. There is no shipyard of any kind, but there may be parts and technical support for doing minor services and repair. Ports of this classification generally consist of only a downport, unless this is a trade port or system with an hostile environment mainworld.

World technology level[edit]

Anarides possesses a Technology Level of TL–8.

  • Common Communication technologies for this TL include: Fiber optics, improved telephones, and satellite communication and data networks.
  • Common Power Generation technologies for this TL include: Improved geothermal and improved batteries.
  • Common Transportation technologies for this TL include:
    • Land: Advanced automobiles.
    • Water: Triphibians and early artificial gills.
    • Air: Improved helicopters and hypersonic jets.
    • Space: Space shuttles, early space stations, and improved interplanetary spacecraft (System Craft).

World government[edit]

Anarides is governed by Self-Perpetuating Oligarchy. A single family or small group provides the leadership and important positions in the government. These positions are inherited by member of the group or their family members. The organization may be monarchy, with titles passed to family members. Or a plutocracy where inheritance of the family fortune includes government position. Or the organization may be more typical organization with positions of power inherited.
