Corelian Subsector is Subsector F of Theta Borealis Sector.

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

World Details: 1105[edit]

Detailed UWP data for all the worlds listed within the subsector can be retrieved from Theta Borealis Sector data files.

Astrographic Features & Trade Routes: 1105[edit]

The following astrographic and commercial data has been determined:


The Korsumug Main, the great chain of Jump-1 systems linking Astron Sector, Theta Borealis Sector, and Mavuzog Sector, runs through the subsector.

  • It is also known as the Thetan Main.
  • The narrow bridge of stars that carries the Main across the Thetan rifts is known as the Korsumug Gate.
  • Korsumug raiders cruise the Main, looking for plunder, resources, and glory.

A simple chart showing Mavuzog Sector, Theta Borealis Sector, the rimward edge of Astron Sector, and the Korsumug Main running between them.

  • The majority of worlds forming the Main lie within Theta Borealis sector.

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.

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.

Chains of giant stars trail out from the cluster into many of the surrounding sectors.

Stellar Distribution[edit]

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

Subsector Summary: 1105[edit]

Corelian, subsector F of Theta Borealis contains 26 worlds with an estimated population of 18 billion, a per capita income of Cr3,142, and a total economy is BCr58,699. These worlds originate an interstellar trade of BCr141 through 23 starports (5 Class A, 4 Class B, 10 Class C, 4 Class D) employing 18,465 people. Driving this interstellar trade are four Agricultural (Ag) worlds, five 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 Corelian maintain one Naval base. The average technology level is 8 (with most between 5 and 10). The highest technology level is 13 at Gutzkow (Theta Borealis 1519).

Corelian, subsector F of Theta Borealis contains 41 stars and 277 identified planets; 16 monostellar systems, seven binary systems, two trinary systems, and one system with four or more stars. 15 of the 26 systems (57%) have native gas giants. There are two Asteroid (As) belts, three Desert (De) worlds, two Garden (Ga) worlds, no Ice-capped (Ic) worlds, five Poor (Po) worlds, three Vacuum (Va) worlds, and no Water (Wa) or Ocean (Oc) worlds.

Corelian has an estimated population of 18 billion distributed across two High population (Hi) worlds, three Moderate population (Ph) worlds, 14 Non-industrial (Ni) worlds, five Low population (Lo) worlds, and no Barren (Ba) worlds. The highest population world is Portine (Theta Borealis 1311). The population consists of 4 sophont groups including two native sophonts.

Non-Aligned, Human-dominated[edit]

There are 21 Non-Aligned Human-dominated worlds in Corelian with an estimated population of 17 billion.

Percavid Marches[edit]

The Percavid Marches has jurisdiction over three worlds with an estimated population of 40 million, a per capita income of Cr2,925, and a total economy is BCr117. These worlds originate an interstellar trade of BCr30 through 2 starports (1 Class A, 0 Class B, 0 Class C, 1 Class D) employing 4,150 people. Driving this interstellar trade are no Agricultural (Ag) worlds, one Non-Agricultural (Na) world, one Pre-Agricultural (Pa) world, one Pre-Industrial (Pi) world, no Rich (Ri) worlds, and no Industrial (In) worlds.

The Percavid Marches has an estimated population of 40 million distributed across no High population (Hi) worlds, no Moderate population (Ph) worlds, two Non-industrial (Ni) worlds, no Low population (Lo) worlds, and no Barren (Ba) worlds. The highest population world is Honiara (Theta Borealis 1120). The population consists of 1 sophont groups.

Non-Aligned, unclaimed[edit]

There are two Non-Aligned unclaimed worlds in Corelian with an estimated population of 700 million.
