Alpha Subsector is Subsector A of Theta Borealis Sector.

  • It lies within Charted Space.
  • On older surveys it may be referred to as the Alpha Quadrant.

Description (Specifications)[edit]

Alpha Subsector is a settled region on the frontier of Balkanized Space.

  • The resources of the subsector are being exploited.

Astrographic Features & Trade Routes[edit]

The following astrographic and commercial data has been determined:

  • The subsector is a relatively low stellar density region.
  • There are two rift regions within the subsector.
  • The brightest star is the blue-white bright giant primary of the Thrace system.
  • No trade routes are noted as crossing the region.

Stellar Distribution[edit]

A basic map showing the distribution and size of stars within Alpha 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.

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.

Rift Regions[edit]

Rift Regions.
The star Theta Borealis is marked in red.

Two rift areas lie within the subsector: the Thetan Rift and a small part of the Gulf of Dalevon.

Locally at least, a rift is an astrographic concept based on Jump Drive performance.

The highest tech level commonly encountered out this Far Along (spinward of the Third Imperium) is TL–12, though a few worlds may be more advanced.

Borealis Group[edit]

Chart Borealis Group Stellar.png

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.

  • Alpha Subsector lies to spinward-coreward of the clusters core, forming part of a long outlying trail of relatively small stars.

Theta Borealis Bright Stars 2.jpg

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 Alpha 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:

  • Verified updated data is constantly sought.

History & Background / Dossier[edit]

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

Alpha Subsector is a relatively backwater region with little activity or development within its borders. This is partly due to the xenophobic mistrust of local Human societies, whose small settlements have formed a trade protection agreement known as "the protectorate". This governs mutual trade agreements, information co-ordination, and protection against invaders and poachers. It is governed by a body of representatives who meet at established periodic intervals. Relationships with "aliens" (those not of the protectorate) are frosty at best, and carefully controlled.

The Siderion system fields the locally manufactured Siderion class Asteroid Ship.

  • A single example of the class has been completed.

Polity Listing[edit]

The following polities can be found within this subsector:

Military Forces[edit]

The powerful Trooles Confederation Navy dominates the region.

Major Historical Events Timeline[edit]


Subsector Summary[edit]

Alpha, subsector A of Theta Borealis contains 26 worlds with an estimated population of 193 million, a per capita income of Cr2,787, and a total economy is BCr538. These worlds originate an interstellar trade of BCr17 through 23 starports (3 Class A, 9 Class B, 8 Class C, 3 Class D) employing 1,815 people. Driving this interstellar trade are four Agricultural (Ag) worlds, two Non-Agricultural (Na) worlds, three Pre-Agricultural (Pa) worlds, one Pre-Industrial (Pi) world, no Rich (Ri) worlds, and no Industrial (In) worlds. The governments in Alpha maintain two Naval bases, and one Scout base. The average technology level is 8 (with most between 5 and 10). The highest technology level is 13 at Boswool (Theta Borealis 0205).

Alpha, subsector A of Theta Borealis contains 37 stars and 254 identified planets; 17 monostellar systems, seven binary systems, two trinary systems, and no systems with four or more stars. 13 of the 26 systems (50%) have native gas giants. There are two Asteroid (As) belts, no Desert (De) worlds, no Garden (Ga) worlds, one Ice-capped (Ic) world, no Poor (Po) worlds, four Vacuum (Va) worlds, and four Water (Wa) or Ocean (Oc) worlds.

Alpha has an estimated population of 193 million distributed across no High population (Hi) worlds, no Moderate population (Ph) worlds, 13 Non-industrial (Ni) worlds, nine Low population (Lo) worlds, and one Barren (Ba) world. The highest population worlds are Magpie (Theta Borealis 0806), Creoll (Theta Borealis 0302), and Poltan (Theta Borealis 0303). The population consists of 4 sophont groups including two native sophonts.

  • Byl: less than 1 million on their homeworld.
  • Irf: less than 1 million on their homeworld.


Non-Aligned, Human-dominated[edit]

There are 18 Non-Aligned Human-dominated worlds in Alpha with an estimated population of 174 million.

Kingdom of Peladon[edit]

The Kingdom of Peladon has jurisdiction over six worlds with an estimated population of 11 million, a per capita income of Cr1,727, and a total economy is BCr19. These worlds originate an interstellar trade of BCr0 through 6 starports (1 Class A, 2 Class B, 2 Class C, 1 Class D) employing 65 people. Driving this interstellar trade are one Agricultural (Ag) world, one Non-Agricultural (Na) world, no Pre-Agricultural (Pa) worlds, no Pre-Industrial (Pi) worlds, no Rich (Ri) worlds, and no Industrial (In) worlds. The governments in Kingdom of Peladon maintain one Naval base, and one Scout base. The average technology level is 9 (with most between 6 and 11). The highest technology level is 11 at Westmoore (Theta Borealis 0410) and Kapalon (Theta Borealis 0509).

The Kingdom of Peladon has an estimated population of 11 million distributed across no High population (Hi) worlds, no Moderate population (Ph) worlds, three Non-industrial (Ni) worlds, three Low population (Lo) worlds, and no Barren (Ba) worlds. The highest population worlds are Krytolon (Theta Borealis 0609) and Kapalon (Theta Borealis 0509). The population consists of 1 sophont groups.
