System Data[edit]

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

Mainworld Data[edit]

Mainworld Size (S)[edit]

Usyupkut is a Meso World between 12,000km and 13,500km in diameter. The world has a standard gravity between 0.8G and 1.1G. The horizon will appear about 5.1km away. Vessels with 1G of thrust should check with local starport authorities before attempting to land using emergency power.

Mainworld Atmosphere (A)[edit]

Usyupkut has a pressure of 1.50 to 2.49 atmospheres. A Dense Atmosphere requires no survival gear although it may be hard on sophonts not accustomed to it.

Mainworld Hydrosphere (H)[edit]

Usyupkut has 55-65% of its surface covered by liquid water. It has significant large liquid bodies. Wilderness refueling is possible.

Mainworld Geography and Topography[edit]

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

History & Background (Dossier)[edit]

Comp-Prog-Dav-R-Deitrick-Starter-Trav-Page-16 16-July-2018a.jpg

Usyupkut lies on the Rhamsteppe-Mongrebi Main, an important trade route. It is a member of the region known as The Access, the long spine of the Main.

It is a part of the Darmine Cultural Region, created within rimward Zarushagar Sector by order of Emperor Artemsus in the years immediately following the Ilelish Pacification Campaign.

The world is believed to contain an archaeological site, supposedly holding extremely advanced remnants of the now-vanished Ancients precursor race.

  • The Droyne authorities actively discourage access to the region where the site is said to be located.

World Starport[edit]

Usyupkut has a Class A Starport, an excellent 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 other kinds of repair, and construction of both starships and non-starships. Most ports of this classification have both a Highport and a Downport.

World Population (P)[edit]

Usyupkut has a population of 700,000 sophonts (hundreds of thousands).

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

Droyne organise themselves into oytripin, which consist of multiple tyafelmin and dreskayin, and can produce kroylosses.

Linguistic Topography[edit]

The most commonly heard language is:

  • Oynprith, a ceremonial and ritualistic language apparently universal among Droyne communities.

Other languages are occasionally heard, including:

World Technology Level[edit]

Usyupkut possesses a Technology Level of TL–12 or TL-C in Hexadecimal Notation.

World Government[edit]

Usyupkut is governed by Self-Perpetuating Oligarchy. A single family or small group provides the leadership and important positions within the government. These positions are inherited by members of the group or by their relatives. The organization may be a monarchy, with titles passed to family members, or a plutocracy where inheritance of the family fortune includes government position. Alternatively, the organization may be a more typical government apparatus, only with positions of power inherited.

World Law (L)[edit]

Usyupkut has a moderate law 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. Light assault weapons, and anything more destructive, are typically regulated or prohibited.

Imperial Landed Nobility[edit]

Usyupkut, as a member world of the Third Imperium, holds the estate of an Imperial Landed Knight who acts as an Imperial representative to the world, and the estate and fiefdom of two members of the Imperial Landed Nobility, who oversee affairs regarding the world at an Interstellar and Imperial level.

Trade Data[edit]

  • Importance: 2 (ordinary)

World Economy[edit]

  • Resources: A (abundant)
  • Labor: 4 (tens of thousands)
  • Infrastructure: 6 (limited)
  • Efficiency: +1 (average)

World Culture[edit]

  • Heterogenity: 3 (monolithic)
  • Acceptance: 7 (aloof)
  • Strangeness: 3 (somewhat typical)
  • Symbols: A (abstract)

World Timeline[edit]

Major events that have affected this world and the wider region that it lies within:

Later Historical Eras[edit]

History: New Era[edit]

Many Droyne refugees fled here to escape persecution during the Rebellion. A hundred years on, Usyupkut was a stable world possessed of a modest trade fleet (some of which were moth-balled refugee ships). It developed strong ties to nearby Human-dominated worlds.
