Duhamel Subsector is Subsector L of Theta Borealis Sector.
- It lies within Charted Space.
- On older surveys it may be referred to as the Duhamel Quadrant.
Description (Specifications)[edit]
Duhamel Subsector is a settled and developed region within Balkanized Space.
- Some worlds have been settled for millennia.
- The resources of the subsector are being exploited.
Astrographic Features & Trade Routes[edit]
The following astrographic and commercial data has been determined:
- Most of the subsector is a standard stellar density region.
- There are no rift regions within the subsector.
- The brightest star is the unstable yellow bright giant primary of the Phonecia system.
- No communications routes are known to cross the region.
Stellar Distribution[edit]
A basic map showing the distribution and size of stars within Duhamel Subsector.
- The color corresponds to the visible color of the star, which links to its spectral classification.
- The size as shown indicates both the physical size of the object and its relative brightness.
(Chart sourced from Traveller Map).
Note that the stars as depicted are representative. Any star, no matter what its size, is a mere speck within the hex it occupies.
- Ordinary main sequence stars can barely be seen from even a hex away.
- Huge, intensely luminous giant stars can be seen from across the subsector and far beyond.
Borealis Group[edit]
The subsector forms part of the Borealis Group, a gigantic, broadly spherical cluster of stars centered on Theta Borealis Sector.
- It is a distinctive, extremely bright feature that can be easily observed from all across Charted Space.
- It is more than 40 parsecs in diameter.
- It contains an unusually high number of giant stars.
- It is the density of giant stars within the region, rather than their individual brightness, that makes the feature so prominent.
Chains of giant stars trail out from the cluster into many of the surrounding sectors.
- Duhamel Subsector lies to trailing of the clusters core, forming part of a long outlying trail of giant stars.
The night-time skies of all of the worlds across the region are studded with a panoply of colorful, intensely bright stars.
- Some are so bright that they can be clearly seen from planetary surfaces during daylight hours.
- The brightest is Theta Borealis, an unstable, violent, blue-white bright supergiant with a luminosity of around 73,000 sols.
- Other extremely bright stars within the cluster include Sigma Borealis, Tau Borealis, Epsilon Borealis, Mu Borealis, and Kappa Borealis.
- While the cluster contains many extremely luminous giant stars, Theta B is exponentially brighter than any of the others.
World Listing[edit]
Comprehensive Second Survey data for all worlds lying within Duhamel Subsector is available.
- The primary source material for all data is Traveller Map.
- Other sources may differ: some elements of the data may be contradictory or incorrect.
- Data is occasionally updated as new information becomes available.
- Scouting missions gathering reliable, verified data can receive substantial payment.
AAB library archives contain expanded data about the following systems:
Note that some Second Survey data, though only 40 years old, may already be out of date.
- Verified updated data is constantly sought.
History & Background (Dossier)[edit]
A few worlds of the region were settled sometime after -1900 by humans originating in the Rule of Man. These isolated settlements survived and even prospered during the Long Night, becoming known as the the Verstand-Jugartha colonies. They served as the focus for waves of settlers originating in what later became the Imperial core, who had gained access to Sylean jump technology and were seeking empty worlds of their own.
Finding their destination worlds already thoroughly governed and relatively heavily populated, later waves of arrivals carried on to spinward, seeking other habitable worlds within the region that they could claim. Although this slow trickle of humanity had effectively ceased by the end of the third century, by the beginning of the twelth century some of these outposts had grown into heavily populated worlds with distinctive cultures of their own. Among these the Nh'ekul culture is one of the most prominent.
Polity Listing[edit]
No polities are known to exist within (or make any claim upon) the subsector.
Native Sophonts[edit]
No Sophont species are believed to have originated in this area.
Demographics[edit]
Significant populations of the following races (sophont species) reside within this area:
- Humaniti (Human races)
- Non-Human Races
- Aslan (Major Race). A few Ihatei scouts exploring to spinward.
Subsector Timeline[edit]
Major events that have affected this subsector and the wider region that it lies within:
- ca -250,000: the Ancients were likely active within Theta Borealis Sector.
- -5415: the Zhodani discover jump drive technology.
- -2396 / 2123AD: the first known human explorers are active in the region (a few wandering Terrans).
- ca -1900: small numbers of humans (Terrans of the Rule of Man) begin founding settlements across Theta Borealis Sector.
- -1776: the Long Night begins.
- Year 0: far to trailing, across the Great Rift, the Third Imperium is founded.
- 100s-200s: a few pioneering Imperial explorers pass through the subsector.
- 300-420: the Imperial First Survey charts the subsector.
- mid-300s: waves of humans with origins in the Imperial core begin settling within the region.
- 500s: Jaibok raiders of the resurgent Korsumug Empire become active on the Korsumug Main.
- 995-1065: the Second Survey charts the subsector.
- 1065: the Imperial Second Survey is published.
Subsector Summary[edit]
Duhamel, subsector L of Theta Borealis contains 31 worlds with an estimated population of 119 billion, a per capita income of Cr4,664, and a total economy is BCr555,068. These worlds originate an interstellar trade of BCr861 through 26 starports (6 Class A, 5 Class B, 14 Class C, 1 Class D) employing 103,505 people. Driving this interstellar trade are eight Agricultural (Ag) worlds, two Non-Agricultural (Na) worlds, one Pre-Agricultural (Pa) world, five Pre-Industrial (Pi) worlds, two Rich (Ri) worlds, and two Industrial (In) worlds. The governments in Duhamel maintain three Scout bases, and one Naval base. The average technology level is 7 (with most between 5 and 10). The highest technology level is 13 at Storm Rider (Theta Borealis 2625).
Duhamel, subsector L of Theta Borealis contains 41 stars and 329 identified planets; 23 monostellar systems, six binary systems, two trinary systems, and no systems with four or more stars. 14 of the 31 systems (45%) have native gas giants. There are two Asteroid (As) belts, one Desert (De) world, one Garden (Ga) world, no Ice-capped (Ic) worlds, one Poor (Po) world, four Vacuum (Va) worlds, and no Water (Wa) or Ocean (Oc) worlds.
Duhamel has an estimated population of 119 billion distributed across three High population (Hi) worlds, one Moderate population (Ph) world, ten Non-industrial (Ni) worlds, nine Low population (Lo) worlds, and one Barren (Ba) world. The highest population worlds are Ratan (Theta Borealis 2822) and Dennson (Theta Borealis 3122). The population consists of 1 sophont groups.
