Zelden is a poor, moderate population non-agricultural and pre-industrial hellworld with a population, over a hundred million, but not yet at a billion sophonts, struggling to survive in an inhospitable environment.

• Hellworlds often offer daily, and sometimes even hourly, life-threatening situations to their inhabitants. Survivors often develop intense survival skills and tend to be grim realists.
• This world is unable to produce quality foodstuffs and must import them.
• It is a world working towards greater industrial capability, but currently lacks an adequate population to expand its industrial sector.
• It is a Non-Aligned world dominated by human sophonts located in the Sibigil Subsector of Theta Borealis Sector.

• This is a hot world, with a climate of high temperatures.

Description (Astrography & Planetology)

Stellar Data

Zelden has a solitary primary star.

• It is a turbulent red giant named Kantro.

Zelden has a solitary primary star.

	Type	Category		Mass (Sol)	Temperature (K)	Luminosity
	M6 III	Giant		7.85	2000 - 2800	2382.5
	Unit	Diameter	Safe Distance	Habitable Zone	Jump Shadow	M-Drive Limit

	Orbit #	5	6	9	12	15
	Remarks		Unstable pulsating star. It produces high levels of EM noise.

System Data

The worlds of the system have been surveyed. They consist of:

• The mainworld.
• x4 secondary rocky worlds.
• x1 planetoid belt.
• x1 gas giant.

Mainworld Data

The mainworld orbits within the star's Habitable Zone.

• It lies within the zone's warmer inner H+ region
• It receives higher levels of stellar energy.

• The world orbits inside the star's enormous Jump Shadow.

Mainworld Size (S)

Zelden is a Meso World between 5,600km and 7,200km in diameter. The world has low gravity between 0.32G and 0.46G. The horizon will appear about 3.6km away.

• The world is seismically and geologically active.

Mainworld Atmosphere (A)

Zelden has a pressure of 0.10 to 0.42 atmospheres. The very thin pressures require a respirator or Oxygen Mask. This atmosphere also contains an unusual taint such as disease, a hazardous gas mix, pollutants, or sulfur compounds, which requires the use of a Filter Respirator Combination Mask. Some taints may require more protective equipment. TL–5 or more advanced survival gear is required to settle this world.

• The world has an abiotic oxygen atmosphere.
• Oxygen is produced by photocatalytic conversion of surface materials by stellar energy.
• Fresh surface material is constantly exposed through processes such as seismic activity, volcanism, or erosion.
• The oxygen rapidly depletes from the atmosphere through oxidization with surface materials: a rough equilibrium between production and depletion exists.
• The percentage of oxygen in the atmosphere varies according to the density of global cloud cover.

Mainworld Hydrosphere (H)

Zelden has 15-25% of its surface covered by liquid water or ice. There may be a few small seas. Wilderness refueling is possible. Water for the inhabitants needs to be imported and extensively recycled. These worlds are Hell Worlds or Poor Worlds depending on their atmosphere.

• The world experiences high temperatures.
• Much of the surface is an arid, hostile environment.

Satellites:

Zelden retains a tiny planetoid moon.

• Its surface is cratered and irregular
• It orbits once every few days.

Mainworld Geography and Topography

No centrally held map of the world exists within AAB Library Data records.

• Locally, detailed maps may be available.
• Verified updated charts are constantly sought.
• Detailed survey data commands premium prices.

Native Lifeforms

No native life: the world has an abiotic oxygen atmosphere.

History & Background (Dossier)

No information yet available.

World Starport (St)

Zelden has a Class B Starport, a good quality installation which includes all the expected amenities including refined fuel for starships, brokerage services for passengers and cargo, and a variety of ship provisions. There is a shipyard capable of doing annual maintenance, overhauls and most kinds of repair, and construction of non-starships. Most ports of this classification have both a Highport and a Downport.

World Demographics (P)

Zelden has a population of 700 million.

Urbanization

A number of large urban centers surrounded by smaller satellite communities.

• Structures and facilities are sealed against local environmental conditions.
• Regional centers may have their own starports.
• Some regions of the surface of the world remain as wilderness.

World Technology Level (T)

Zelden 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 (G)

Zelden is governed by a Representative Democracy where government leadership is by representatives elected by eligible voters. What determines an eligible voter varies. The representatives determine policy, including selecting members of the bureaucracy. There can be referenda, votes by eligible voters on specific subjects.

World Military

Approximately 2 million personnel.

World Law (L)

Zelden has a moderate level with laws covering many areas of government and interaction. These laws are simple enough that most people can act as their own advocate, though for serious issues a professional is recommended. Law enforcement officials will be present, but not in great numbers. Personal concealable firearms, and anything more destructive, are typically regulated or prohibited.
