Jump map from Travellermap.com

Pebble is a low-population vacuum world, with a population of less than 10,000 sophonts, warranting hazardous environment precautions.

• Life in a vacuum requires great discipline. After all, it only takes one forgotten seal on a vacuum suit to spell death. Those who survive tend to be very methodically-minded and attentive to small detail.
• It is a member of the Talpaku Communality in the Talpaku Subsector of Yiklerzdanzh Sector.

• This dangerous world is designated an Amber Zone with an environment, laws, customs, life forms, or other conditions that make it dangerous to visitors.

Description (Astrography & Planetology)

Stellar Data

Pebble is a binary star system.

• The primary is a red main sequence.
• The secondary is a white dwarf stellar remnant

Pebble has two stars in the star system.

System Data

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

• The mainworld.
• An unknown number of secondary rocky worlds.
• x3 planetoid belts.
• x3 gas giants.

Mainworld Data

Pebble orbits towards the outer edge of its star's habitable zone.

• It receives relatively low levels of stellar energy.

It has a slow rotation period: one local day is equivalent to 3.6 standard days (around 85 standard hours).

Mainworld Size (S)

Pebble is a Small World between 900km and 2,400km in diameter. The world has very low gravity between 0.05G and 0.09G. The horizon will appear about 2km away.

Mainworld Atmosphere (A)

Pebble has a pressure of less than 0.001 atmospheres which requires the use of a Vacc Suit. TL–8 or more advanced survival gear is required to settle this world.

• Vacuum worlds have no climate, but experience extreme differences in temperature between direct starlight and shade.

Mainworld Hydrosphere (H)

Pebble has no free-standing water or ice on the surface. Wilderness refueling isn't possible on this world. Water for the inhabitants needs to be imported and extensively recycled. These worlds are classified Desert World or a Hell World depending on their atmosphere.

Satellites

Pebble does not retain any moons.

Mainworld Geography and Topography

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

(Blank map, vacuum world.)

History & Background (Dossier)

Pebble is a Danger World and is designated as an Amber Zone. It presents particular risks and dangers due to the environment or native life forms, laws or customs, or other conditions that are not well understood.

• Visitors are advised to act with caution.

World Starport (St)

Pebble has a Class E Starport, a frontier quality installation with few 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 a downport.

World Population (P)

Pebble has a population of 7,000 sophonts (thousands).

• This is a Low Population World and the population would be too low to sustain itself without a little outside assistance. This may represent the home base of a sizable but mostly transient population such as the base of a major starship expedition, the last generation of a dying colony, the first generation of a new colony, or a large outpost that will probably evolve into a colony if not stopped.
• The population almost entirely consists of Talpaku.
• A few humans and other sophonts may be encountered.

Linguistic Topography

Talpaku, a language comprised of whistles and clicks, is commonly used on the world.

• Talpaku cannot vocalize human sound, and even the most skilled humans can only poorly imitate spoken Talpaku.
• Language Translators are widely used for inter-species communication.

World Technology Level (T)

Pebble 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)

Pebble has no central government or substantial government apparatus; an Anarchy. The largest governmental structure would be a family, tribe, or single clan. The largest group will be between 50 and 100 individuals, and there may be dozens to hundreds of them. This governmental structure can be stable over long periods of time if the population remains small or geographically separated.

World Law (L)

Pebble has no law in practice. It is an Anarchy. On many worlds, this by itself justifies an Amber Zone advisory. There are few laws, covering only important areas. There may be few or no law enforcement officers, the expectation is citizens will bring law breakers to the attention of the Judicial system. Legal proceedings will be fast, with few people involved. For interactions outside of the framework of the laws, cultural norms dominate.

World Economy

Each world in the Talpaku Communality has its own currency, the values of which fluctuate against each other according to economic circumstances.

There is a "reference" unit of currency called the kuyo, which is used by the Communality government, by multistellar companies, and for transactions between individuals and companies on different worlds.

World Culture

The world lies within the Zhodani Shadow, a region strongly influenced by the society and culture of the Zhodani Consulate.
