System Data[edit]

Horovan-Eigh System[edit]

The primary is Horovan, an ordinary orange main sequence star. It has a luminosity of 0.42 Sols, a mass of 0.825 Sols, and a diameter of 1.263 million km. The inner system consists of (I) a vacuum worldlet and (II) a dense atmosphere stormworld. (III) Eigh orbits within the habitable zone and is designated the mainworld. (IV) a standard atmosphere bigworld, (V) a small gas giant, (VI) a small ice giant and (VII) a vacuum iceworld form the outer system. Many of the worlds retain satellites.

Ranedos Subsystem[edit]

The companion is Ranedos, a dwarf star that lies approximately 147 AU (orbital position (XII), 2.5 billion km) from Horovan: the two stars orbit their barycenter, located within orbital position (XI), once every 1400 years. Ranedos has a luminosity of 0.00004 Sols, a mass of 0.83 Sols, and a diameter of 12,500 km. The outer system consists of (I) a sparse icy planetoid belt.

Mainworld Data[edit]

(III) Eigh[edit]

(III) Eigh is designated the mainworld. It orbits Holovan at a mean distance of 0.66 AU (98.7 million km), within the habitable zone. It has an orbital period of 215 days 15 hours and a rotation period of 20.5 hours. The axial tilt is 16 degrees. Eigh has a diameter of 9,377 km, a density of 5.22 g/cm³, and a surface gravity of 0.70 G. The world is geologically active. Its atmosphere is rated as Thin, Tainted, with a mean surface pressure of 0.62 bar and a composition of 88% nitrogen (N2), 19% oxygen (O2), 1%, argon (Ar), 0.5% neon (Ne), 0.5% xenon (Xe), and 1% water vapor (H2O), carbon dioxide (CO2) and other trace gases. The atmospheric taint is caused by the high percentage of inert gases. Approximately 38% of the surface is covered in seas of liquid water: average tidal ranges exceed 0.25m. Mean surface temperature: 9°C. The climate is rated as Temperate-Cool 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.

Mainworld geography and topography[edit]

Total surface area: 276 million km², Land surface area: 171 million km², Water surface area: 105 million km².

  • Breathing the atmosphere without protective measures can result in argon, neon and xenon pooling within the lungs, eventually causing inert gas asphyxiation. Breathing untainted air will rapidly clear any such pooling. Symptoms include a noticeable deepening of the voice, a persistent headache, dizziness, confusion, and physical tremors. Prolonged exposure can cause nausea, vomiting, unconsciousness, coma and death.

Native lifeforms[edit]

Eigh has primitive native life, consisting entirely of microscopic cyanobacteria-parallels that exist in almost every ecological niche. Their metabolic functions maintain the process of atmospheric renewal.

History & Background (Dossier)[edit]

No information yet available.

World starport[edit]

Eigh 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]

Eigh possesses a Technology Level of TL–4.

  • Common Communication technologies for this TL include: Telephone and telegraphs, widespread printing.
  • Common Power Generation technologies for this TL include: Early electricity, hydrocarbon internal combustion.
  • Common Transportation technologies for this TL include:
    • Land: Trains and early automobiles.
    • Water: Clippers and steam ships.
    • Air: Dirigibles, balloons, very basic rockets.

World government[edit]

Eigh has a Self-Perpetuating Oligarchy government.

  • It is a government by a restricted minority, with little or no input from the masses.
  • The typical power source of this government is an Oligarchy.
  • The typical power structure of this government is a Hegemony.
