K'shek is a pre-agricultural, pre-Industrial, moderate population world with over a hundred million, but not yet at a billion sophonts in population size.

  • It requires significant imports of outside technology to maintain a modern, star-faring society.
  • Its economy and population are growing and living conditions are expected to slowly improve barring outside forces.
  • It is a member of the Sath Alliance in the Sath Subsector of Far Home Sector.
  • Warning: Humans are not welcome within the Sath Alliance. Those few humans that venture into its territory are generally met with a hostile reception and are closely monitored at all times.

System Data[edit]

Kh'isaa-Kshek System[edit]

The primary is Kh'isaa, a hot blue-white main sequence star. It has a luminosity of 75.2 Sols, a mass of 3.22 Sols, and a diameter of 4.063 million km. The inner system consists of (I) a dense stony planetoid belt, and (II) a vacuum worldlet. Orbital positions (III) through (VI) are unavailable due to the presence of the companion star. (VII) K'shek orbits within the habitable zone and is designated the mainworld. (VIII) a trace hospitable world, (IX) an exotic atmosphere radworld, (X) a trace atmosphere iceworld, and (XI) a vacuum iceworld form the outer system. Many of the worlds retain satellites.

Is'shka Subsystem[edit]

The companion is Is'shka, a dim red subdwarf star that orbits Kh'isaa at a mean distance of 0.89 AU (orbital position (IV), 133 million km) and has an orbital period of 171 days. It has a luminosity of 0.00152 Sols, a mass of 0.093 Sols, and a diameter of 127,000 km. It retains (I) a sparse stony planetoid belt, and (II) a vacuum worldlet. The worldlet retains a satellite. The Is'shka subsystem lies entirely within Kh'isaa's inner system.

Ish Subsystem[edit]

The far companion is Ish, a magenta-coloured L-type brown dwarf lying approximately 1700 AU from Kh'isaa. It is not luminous, it has a mass of 0.062 Sols and a diameter of 60,000 km. (I) a dense icy planetoid belt, and (II) a trace atmosphere worldlet form the outer system. The worldlet retains a satellite.

Mainworld Data[edit]

(VII) K'shek[edit]

(VII) K'shek is designated the mainworld. It orbits Kh'isaa at a mean distance of 9.72 AU (1.45 billion km), within the habitable zone. It has an orbital period of 16 years 325 days and a rotation period of 26.5 hours. The axial tilt is 18 degrees. K'shek has a diameter of 11,365 km, a density of 5.24 g/cm³, and a surface gravity of 0.85 G. The world is geologically very active. Its atmosphere is rated as Dense, Tainted, with a mean surface pressure of 1.79 bar and a composition of 72% nitrogen (N2), 27% oxygen (O2), and 1% argon (Ar), water vapor (H2O), carbon dioxide (CO2), ozone (O3), neon (Ne) and other trace gases. The taint is caused by the high percentage of atmospheric oxygen. Approximately 67% of the surface is covered in oceans of liquid water: average tidal ranges exceed 0.3m. Mean surface temperature: 29°C. The climate is rated as Temperate-Warm and experiences minor seasonal changes during the local year. The atmosphere is active and powerful weather systems driven by the star and the oceans sweep across the globe.


K'shek retains two natural satellites, a cratered vacuum worldlet named Chaa and a trace atmosphere ice-capped worldlet named Ik'sch:

(VIIa) Chaa (UWP Y100000-0, orbiting at 9 Diameters/100,000 km)
(VIIb) Ik'sch (UWP Y311000-0, orbiting at 45 Diameters/510,000 km)

Mainworld Geography and Topography[edit]

Total surface area: 406 million km², Water surface area: 272 million km², Land surface area: 134 million km².

  • Breathing K'shek's atmosphere without suitable filtration equipment will cause oxygen narcosis and oxygen toxicity. Symptoms include sensations of euphoria and nausea, seizures, bouts of physical rigidity followed by convulsions and unconsciousness. Prolongued exposure causes acute breathing difficulties, damage to the lungs and the heart, and death.

Native Lifeforms[edit]

Kh'isaa-Kshek System[edit]

K'shek, the mainworld, has extensive, abundant native life, with complex organisms inhabiting every ecological niche. Their metabolic functions drive the process of atmospheric renewal.

No other world in the subsystem is known to have native life.

Is'shka Subsystem[edit]

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

Ish Subsystem[edit]

No native life is known to exist within the subsystem.

History & Background (Dossier)[edit]

This system is controlled by the Shikh'aa Faction of the Sath Alliance.

World starport[edit]

K'shek 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]

K'shek possesses a Technology Level of TL–4.

World government[edit]

K'shek has a Balkanized Government. There is no central world government. The world has several governments competing for control of the world. These may be allies, cooperating, competitors, or at war with each other.

Different minor Factions, all nominally loyal to the Shikh'aa Faction, control nation-territories.
