System Data[edit]

Appine-Hellash System[edit]

The primary is Appine, an ordinary white main sequence star. It has a luminosity of 4.42 Sols, a mass of 1.38 Sols, and a diameter of 2.031 million km. The inner system consists of (I) a vacuum inner world, (II) a trace atmosphere worldlet, (III) an exotic atmosphere stormworld, and (IV) a corrosive atmosphere inferno world. (V) Hellash orbits within the habitable zone and is designated the mainworld. (VI) a dense icy planetoid belt, (VII) a large gas giant, (VIII) a ringed large gas giant, and (IX) a large gas giant form the outer system. Many of the worlds retain satellites.

Mainworld Data[edit]

(V) Hellash[edit]

(V) Hellash is designated the mainworld. It orbits Appine at a mean distance of 4.96 AU (742 million km), within the habitable zone. It has an orbital period of 9 years 147 days and a rotation period of 28.5 hours. The axial tilt is 17 degrees. Hellash has a diameter of 16,688 km, a density of 7.23 g/cm³, and a surface gravity of 1.71 G. The world is geologically extremely active. Its atmosphere is rated as Dense, Tainted, with a mean surface pressure of 2.38 bar and a composition of 80% nitrogen, 19% oxygen, and 1% argon, water vapour, carbon dioxide, sulfur dioxide, carbon monoxide, neon and other trace gases. The atmospheric taint is caused by gases and sulfur compounds of volcanic origin. Approximately 74% of the surface is covered in oceans of liquid water: average tidal ranges exceed 0.3m. Mean surface temperature: 33°C. The atmosphere is dynamic and violent weather systems driven by the star and the oceans surge across the globe. The climate is seasonal.


World retains two natural satellites, a trace atmosphere worldlet named Preek and a corrosive atmosphere inferno world named Basook:

(Va) Preek (UWP Y210000-0, orbiting at 25 Diameters/417,000 km)
(Vb) Basook (UWP Y5B0000-0, orbiting at 30 Diameters/501,000 km)

Mainworld geography and topography[edit]

Total surface area: 875 million km², Water surface area: 648 million km², Land surface area: 227 million km².

Native lifeforms[edit]

Hellash has extensive native life. Their metabolic functions power the process of atmospheric renewal.

World technology level[edit]

Hellash possesses a Technology Level of TL–7.

  • Common Communication technologies for this TL include: Early video and early satellite communication networks.
  • Common Power Generation technologies for this TL include: Early fuel cells, solar energy, and geothermal power sources.
  • Common Transportation technologies for this TL include:
    • Land: Improved automobiles, hovercraft, and bullet trains.
    • Water: Hydrofoils and early triphibians.
    • Air: Hang gliders and supersonic jets.
    • Space: Deep space probes and interplanetary spacecraft (System Craft).

World government[edit]

Hellash 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.
