System Data

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

• The mainworld. It is the fourth major moon of the system's only gas giant.
• x10 secondary rocky worlds,
  • None are currently named or surveyed.
• x1 gas giant named Gloin, orbiting the primary star within the habitable zone.
  • It has a family of five major moons.

(Expanded system data is available here.)

Mainworld Data

Froin is the fourth moon of the gas giant Gloin.

The mainworld and its gas giant primary orbit within the star's Habitable Zone.

• They lie within the zone's colder outer H- region.
• They receive lower levels of stellar energy.

The Froin system is characterized by its old central red dwarf, its single gas giant, and smaller companion red dwarf star, Aoin. The system age is roughly 9 billion years.

Gloin is a large gas giant with a family of five major moons. Of its satellites only Froin, the fourth out from the giant world, is habitable: the others are small dead vacuum rocks with navigational beacons planted on their surfaces.

• Currently, the beacons on Gloin I and II are not functional.

Mainworld Size (S)

Froin is a Meso World between 7,200km and 8,800km in diameter. The world has a standard gravity between 0.4G and 0.57G. The horizon will appear about 4km away.

Mainworld Atmosphere (A)

Froin has a pressure of 0.10 to 0.42 atmospheres. The very thin pressures require a respirator or Oxygen Mask. TL–5 or more advanced survival gear is required to settle this world.

• It experiences low temperatures.

Mainworld Hydrosphere (H)

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

• The world's sea are littered with icebergs and pack ice.

Mainworld Geography and Topography

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

(Blank map, predominantly dry world.)

Geographical Features

Froin is an old rock with a fair amount of metals, mostly radioactive endpoint elements. The core is still warm due to gravitational stretching from its giant neighbor. There is a large icepack around each of the polar regions. Two large, interlinked craters are evident on the "spinward" side of Froin. The main settlement is located in the smaller crater, Crater Deep; the downport is located in the center of the second crater, Crater Shallow. The downport Crater is approximately 80 km in diameter and 13 km deep at center. A two-trackway pressurized transit system connects the starport/town to the settlement.

A crater impact that carved a semicircular zone into the edge of the southern icepack houses an Imperial Research Area known as Research Station Zeta. Crater Zeta is around 30 km across.

History & Background (Dossier)

Froin was a ball of low grade rock with few resources and nothing to attract major settlement. It was first discovered by the Darrians in the pre-Maghiz period, who accorded it no importance. It was equally ignored by the Third Imperium during their expansion into District 267 in the 400s. This isolation eventually attracted the Ministry of Science's attention, when it was looking for a world to build the Spinward Marches' Research Station Zeta.

The world is commonly referred to as being on the "ass-end of space". It is a cold, dim nowhere with no real neighbors and few visitors. While there is a settlement focused on mining rich seams of ores exposed by the meteor strike that created the smaller crater, some 90% of the population is employed at the Crater Downport. The main activity here is to serve the enterprising (or foolish) traders that made it out this far.

World Starport (St)

Froin has a Class C Starport, an average quality installation which features amenities including unrefined fuel for starships, some brokerage services for passengers and cargo, and a variety of ship provisions. There is a shipyard capable of doing maintenance and other kinds of repair. Ports of this classification generally have only a downport, unless this is a trade port or system with an hostile environment mainworld.

The Shallow Downport and the Shallow Startown make up the bulk of employment and trade opportunities. Employment is offered in all areas of administration, engineering, gravitics, jump-tech, material working, robotics, etc. Lower tech trades are also present: Chandlers, freight workers, warehousing, longshoremen, animal handlers, etc. In addition, several technical and trade schools are based at the port. The planetary post office is also present here.

World Population (P)

Froin has population of 600 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.

Urbanization

The Settlement in the Crater Deep is focused on mining metal ores, refining them, and transporting them to the starport. Structures tend to be mostly underground, connected by tunnels or pressurized tubes over the surface. Public transit is commonly available, but dirty and generally in a barely functional state. Family abodes tend to be grouped in Inverts, which are a series of chambers cut into the rock off of a central shaft, in a manner somewhat like an inverted skyscraper of other worlds. Family and sub-cultural structure are strong in the Settlement. Schools are grouped by Invert and Invert-hex.

There are advanced communications networks in place with triple redundancy throughout the Craters. Only wireless communications exist with Research Station Zeta; that and a hard overland trek to the security checkpoint.

Linguistic Topography

The following languages are most commonly heard:

• Anglic, one of the two official languages of the Imperium.
• Vilani, one of the two official languages of the Imperium.

World Technology Level (T)

Froin possesses a Technology Level of TL–9.

• Common Communication technologies for this TL include: Fiber optics and satellite communication and data networks.
• Common Power Generation technologies for this TL include: Early fusion power.
• Common Transportation technologies for this TL include:
  • Land: Ultra high-speed trains and early grav vehicles.
  • Water: High efficiency sailcraft, multihulled seacraft, improved artificial gills.
  • Air: Tiltrotorcraft, exotic VTOL's, PARWIG, and rocket-assisted suborbitals.
  • Space: SSTO spacecraft, early military spacecraft (System Craft), and interstellar STL starships
  • FTL: Prototype Jump Drive-1.

World Government (G)

Froin 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.

Froin runs itself as a democracy; everyone who has spent at least 200 days on the surface over the last standard year who registers to vote at least 10 days before an electoral event is a legal voter.

There is an elected President, Vice-President, a unicameral Board of Laws (32 members) and a Judicial Court of Law. 3 Common Courts handle most cases; appeals and special cases are heard by the Judicial Court. The Vice-President administrates the meetings of the Board of Laws, and may break ties.

World Law (L)

Froin 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.

Imperial Landed Nobility

Froin, as a member world of the Third Imperium has a member of the Imperial Landed Nobility who acts as an Imperial representative to the world.

• It holds the estate of an Imperial knight.

Trade Data

• Importance: -1 (unimportant)

Froin's primary export are metals, primarily lead, depleted uranium, and bismuth.

World Economy

• Resources: 5 (scarce)
• Labor: 1 (tens)
• Infrastructure: 0 (non-existent)
• Efficiency: -3 (poor)

World Culture

• Heterogenity: 1 (monolithic)
• Acceptance: 1 (extremely xenophobic)
• Strangeness: 3 (somewhat typical)
• Symbols: 7 (somewhat concrete)

Local culture is disjointed, with many disparate sub-cultures based on common origins, species, and interests. Many races have arrived here over the years. Imperial humans are the majority, but Darrians, Sword Worlders, a Vargr pack, and a Mewey trading enclave also make their home here. No Zhodani are known to live on Froin.

Sports are a central theme in the overall culture, and fuel stories, politics and occasional riots. Various sports are popular across the sub-cultures, and form a major bonds across otherwise different groups. There are 3 major arenas in the Crater Shallow Startown, and 2 in the Crater Deep Settlement. Smaller gyms and arenas exist.

Education is provided to age of 18, focusing on trade-based education and starship-repair professions. A small university exists in the startown, called Hope University.

Marriage customs vary by subcultural standards, but generally follow Imperium norms. Marriages are generally considered a religious custom, and accompanied by relatively large celebrations. Local government will register any marriage recognized by any clergy, but clergy-recognition is required. Couples are the norm, though some plural marriages exist, including at least one group marriage which is a sub-culture unto its own.

Burial customs also vary by subcultural standards, but are ruled by economics. Simple burial under a meter of frozen soil on the open surface is most common. Other groups excavate catacombs; these can span multiple levels for hundreds of meters. Burial customs typically involve wrapping the deceased with fabric inscribed with messages and adorned with small items.. The deceased is then frozen solid for burial.

Later Historical Eras

Post-Collapse

But the world underwent a major expansion after the Collapse. While not as important as Iderati or Emape, about twenty percent of all the Mortal Coil's traffic passes through its huge port. Most ships that pass through are low jump independents that are making an interface from the Coil along the lower Spin Main into Plankwell on their way to Collace or Forine. About ninety percent of the population is employed at the starport at this point. The port becomes the fourth largest in Five Sisters, and unsupervised automation became a necessity out of the huge traffic load and the overworked staff.
