Belethan is a preindustrial hellworld with a challenging environment.

  • The inhabitants of this world struggle to survive in the life-threatening environment of a desert hellworld.
  • This world has little to no free-standing water.
  • The world is a preindustrial one, which cannot produce adequate materials to maintain a modern, star-faring society. These items must be imported at considerable cost.
  • This world has few easy prospects for significant economic development. The inhabitants of this world are searching for economic prospects capable of leading them to prosperity.
  • This a "low technology" world with technology competency well below technology standards for Charted Space.
  • It is a Non-Aligned world dominated by human sophonts located in the Tsorva Subsector of Halcyon Sector.

System data[edit]

Hollis-Belethan System[edit]

The primary is Hollis, a hot white main sequence star. It has a luminosity of 60.4 Sols, a mass of 2.76 Sols, and a diameter of 3.67 million km. The inner system consists of (III) a sparse stony planetoid belt, (IV) a vacuum inner world, (V) a corrosive atmosphere inferno world, (VI) a thin atmosphere bigworld, and (VII) a thin atmosphere inner world – orbital positions (I) and (II) are empty. (VIII) Belethan orbits within the habitable zone and is designated the mainworld. (IX) an exotic atmosphere bigworld, (X) a vacuum worldlet, and (XI) a vacuum iceworld form the outer system. Many of the worlds retain satellites.

Mainworld Data[edit]

(VIII) Belethan[edit]

(VIII) Belethan is designated the mainworld and orbits Hollis at a mean distance of 10.8 AU (1.62 billion km), within the habitable zone. It has an orbital period of 21 years 133 days and a rotation period of 29 hours. The axial tilt is 16 degrees. Belethan has a diameter of 7,776 km, a density of 5.28 g/cm³, and a surface gravity of 0.58 G. The world is geologically active. Its atmosphere is rated as Dense, Tainted, with a mean surface pressure of 1.95 bar and a composition of 77% nitrogen, 22% oxygen, and 1% argon, carbon dioxide, neon and other trace gases. The taint is caused by the extremely low atmospheric humidity and large quantities of fine wind-borne dust. Less than 0.1% of the surface is covered in lakes of liquid water. Mean surface temperature: 54°C. The atmosphere is dynamic and violent weather systems, driven by the star, sweep across the globe. The climate is seasonal.


Belethan retains two natural satellites, barren vacuum moons named Ardak and Varlot:

(VIIIa) Ardak (UWP Y200000-0, orbits at 11 Diameters/86,000 km)
(VIIIb) Varlot (UWP H300000-0, orbits at 30 Diameters/233,000 km)

Mainworld geography and topography[edit]

Total surface area: 109 million km², Land surface area: 109 million km², Water surface area: less than 100,000 km²,

Native lifeforms[edit]

Belethan has widespread native life, entirely consisting of extremophile microorganisms that can survive in a wide variety of environments. Their metabolic functions drive the process of atmospheric renewal.
