System Data

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

• The mainworld.
• x6 secondary rocky worlds.
• x1 gas giant.

Mainworld Data

Tremous Dex orbits just within the outer system.

Mainworld Size (S)

Tremous Dex 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)

Tremous Dex has a pressure of less than 0.1 atmospheres which requires the use of a Vacc Suit. TL–8 or more advanced survival gear is required to settle this world.

• It experiences low temperatures.

Mainworld Hydrosphere (H)

Tremous Dex has 05-15% of its surface covered by ice, either in vast sheets or contained deep within craters or fractures on the surface. Wilderness refueling is possible. Water for the inhabitants can be got by mining and melting ice.

• The surface of the world is composed of a crust of ice many kilometers thick.
• Much of the surface is cratered and covered in thick layers of regolith and dust of meteoric origin, leaving only a part of the icy outer shell exposed.
• Below the outer icy shell there may be a world-ocean of liquid water.

Mainworld Geography and Topography

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

(Blank map, trace atmosphere world.)

History & Background (Dossier)

Following the Fourth Frontier War Tremous Dex was a non-aligned protectorate of the Zhodani Consulate. The Zhodani constructed basic infrastructure and factories, including a high tech facility able to manufacture laser weaponry (such as laser pistols, laser rifles, and starship weaponry) to supply the needs of the Consulate military. In 1084 the Consulate military contract came to an end and the production facilities were sold to Fantek Personal Defense Inc., who along with the physical structures and equipment also acquired the right to produce all pre-1050 designs.

World Starport (St)

Tremous Dex 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 Population (P)

Tremous Dex has a population of 20,000 sophonts (tens of thousands).

• This is a Nonindustrial World, too small to support the complete chain of production of most goods from start to finish.

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)

Worldname possesses a Technology Level of TL–12 or TL-C 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 & Air: Personal G-Tubes and advanced gravcraft.
  • Space: Advanced interplanetary spacecraft (System Craft).
  • FTL: Jump Drive-3.

World Government (G)

Tremous Dex is governed by a Corporate Polity, having a single corporation with a typical corporate structure as a government. Essentially, this is a "company town" (or world). The typical corporate-run world usually has a single purpose. Examples include mining, agriculture, or other kinds of resource extraction. But rather than a simple base of operations, there are facilities for housing workers and their families, including hospitals, schools, and other infrastructure. How, or if, the children of the workers are incorporated into the workforce varies with companies. The corporation running the world may be a subsidiary of a larger interstellar corporation.

World Law (L)

Tremous Dex has a low law level. 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. Body pistols, explosives, and poison gas are typically regulated or prohibited.

Following the Fifth Frontier War, Tremous Dex joined the Federation of Arden and by 1120 was building starships for the Federation. While the Starport remains class B and has not been upgraded as it is not a commercial facility, the shipyards are new and utilize the latest high-technology manufacturing techniques.

History-Era: New Era

Between the end of the Rebellion and 1200 Tremous Dex switched allegiance to the Regency of Deneb.
