Echo Prime is a low-population world with a population of less than 10,000 sophonts in size.

• This world has yet to take off economically or otherwise and the population remains low for reasons largely unknown.
• It is a member of the Solomani Confederation in the Carcosa Subsector of Aldebaran Sector.

• This world-system has a Naval Base, usually associated with military starships, which may be located on or off-world.
• It has an elliptical orbit around its star.

System Data

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

• The mainworld.
• x8 secondary rocky worlds.
• x1 vast icy planetoid belt, lying in the far outer system.
• x2 gas giants.

All of the secondary worlds and gas giants within the system display some degree of orbital eccentricity.

Mainworld Data

Echo Prime has an elliptical orbit around the primary. It has a mean orbital distance of 1.03 AU and an orbital period of 380 standard days.

• At perihelion it is 0.94 AU from the star and at aphelion it is 1.11 AU from the star.

Except at the extreme point of perihelion, Echo Prime orbits within the star's habitable zone.

Mainworld Size (S)

Echo Prime is a Meso World between 10,400km and 12,000km in diameter. The world has a standard gravity between 0.7G and 0.9G. The horizon will appear about 4.7km away.

Mainworld Atmosphere (A)

Echo Prime has a pressure of 0.43 to 0.70 atmospheres. While the thin atmosphere does not require survival gear 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 Mask. Some taints may require more protective equipment. TL–3 or more advanced survival gear is required to settle this world.

• It experiences generally moderate temperatures.
  • Temperatures at perihelion are high, while temperatures at aphelion are low.

Mainworld Hydrosphere (H)

Echo Prime has 45-55% of its surface covered by liquid water. Wilderness refueling is possible.

• At aphelion the world's seas become crusted with pack ice.

Mainworld Geography and Topography

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

Echo Prime has large ice caps that grow and recede depending on where the world is in its orbit. Surface water also freezes and flows with that cycle.

(Blank map, predominantly dry world.)

Native Lifeforms

Abundant native life occupying every available ecological niche. Its metabolic functions drive the process of atmospheric renewal.

• Native life is adapted to the world's year-long hot-cold cycle.

History & Background (Dossier)

Echo Prime is a former rimward military "hardpoint" system of the Solomani Confederation. Now, it is considered the ass-end of space.

World Starport (St)

Echo Prime 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.

• This world is host to a Confederation Naval Base.

World Population (P)

Echo Prime has population of 200 sophonts (hundreds).

• This is a Low Population World and the population would be too low to sustain itself without moderate outside assistance. This may represent a large transient population such as the crew of a fleet of starships, the dwindling remnants of a dying colony, a construction team building a new colony, or an outpost that could evolve into a colony.
• The population almost entirely consists of Solomani humans.

Urbanization

A small community lies just outside the downport. The citizens live alone or in groups of two or three in single family houses, generally with 1 floor, and constructed of hardcrete with excellent TL–10 amenities.

Linguistic Topography

The most commonly heard languages are:

• Rim Anglic, a dialect of Anglic and the principal language of the Confederation.

World Technology Level (T)

Echo Prime possesses a Technology Level of TL–10 or TL-A in Hexadecimal Notation.

• Common Communication technologies for this TL include: Holovision, Personal Global Communications, and advanced Translators.
• Common Power Generation technologies for this TL include: Increasingly advanced fusion plants and advanced fuel cells.
• Common Transportation technologies for this TL include:
  • Land & Water: Grav belts and maturing gravcraft.
  • Air: Greatly improved hybrid grav-aircraft.
  • Space: Improved interplanetary spacecraft (System Craft).
  • FTL: Jump Drive-1.

World Government (G)

Echo Prime is governed by a Participatory Democracy where eligible voters determine laws and policy. What determines an eligible voter varies. There may be smaller councils or regional bodies to draft the policies voted upon. Leadership of the government and all members of the bureaucracy are determined by the voting population.

World Military

The world depends on the local Naval station for defense. While now deprioritized, the Naval station is still well-kempt and actively visited by warships on a regular basis.

World Law (L)

Echo Prime 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.

Trade Data

• Importance: 1 (ordinary)

World Economy

A few of the citizens choose to work at the downport or on the highport.

• Resources: B (abundant)
• Labor: 1 (tens)
• Infrastructure: 1 (extremely limited)
• Efficiency: +2 (good)

World Culture

The population is generally Confederation ex-military that decided to stay here during retirement. They like being alone, and would prefer to stay that way.

• Heterogenity: 3 (monolithic)
• Acceptance: 3 (xenophobic)
• Strangeness: 7 (confusing)
• Symbols: 7 (somewhat concrete)
