Theta Borealis Sector
Theta Borealis Sector is a distant region located in non-aligned space, far to spinward of the Third Imperium.
- It is part of Charted Space.
- It is named for Theta Borealis, a supergiant star lying close to its center.
- The occasional Zhodani, Aslan, or Imperial trader has ventured upon the place, but few make the trip.
Description (Specifications)[edit]
Theta Borealis Sector lies on the far spinward edge of Charted Space.
- It is a relatively densely populated sector in a largely empty region of space.
The sector was initially surveyed during the Imperial First Survey.
- First Survey primary data on the sector was very fragmented.
The sector was extensively surveyed during the Imperial Second Survey.
- IISS personnel based at Pautho, an Imperial Client State, were heavily involved in gathering and collating the survey data.
- Much of the updated data relating to the sector was based on remote long-term observations done over approximately 70 years (from 995 to 1065).
- Most of the output from these observations was automatically generated.
World Listings: 1105[edit]
Comprehensive Second Survey UWP data for all worlds lying within the sector can be retrieved from Theta Borealis Sector data files.
- 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.

Mains[edit]
The Korsumug Main, the great chain of Jump-1 systems linking Astron Sector, Theta Borealis Sector, and Mavuzog Sector, runs through the region.
- It is also known as the Thetan Main.
- It is a Long Main (more than 51 worlds).
- It passes through the spectacular heart of the Borealis Group.
- 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.

Dennson Main
The Dennson Main is a "Short Main" (a main consisting of between 11 and 50 worlds).
- It is named for Dennson, its most important world.
- It lies on the rimward edge of the Thetan Void.
Worlds in blue lie on the Dennson Main.
Worlds in purple lie on the Korsumug Main.
- Dennson is marked in red.
- Jelmirt, the Capital of the Percavid Marches, is marked in yellow.
Calibration Points[edit]
Three Calibration Points (deep space refuelling points, locally referred to as "Hubs") are located within Theta Borealis Sector:
- Nezal Hub (hex 1812, Phoenix Subsector)
- Latol Hub (hex 2318, Phoenix Subsector)
- Deepspace Hub (hex 3117, Sibigil Subsector)
These Hubs are corporate-operated and not generally available to non-corporate personnel or vessels.
- Their presence is not displayed on commercially available star charts.
- Their exact location within their respective hexes is not publically available.
Hexes are extremely large, in the region of 3.2 lightyears / 170 light weeks across.
- Without exact coordinates to jump to within it, any ship arriving randomly within the hex is likely to end up many tens of light-weeks away from the Calibration Point.

Clusters & Traces[edit]
Borealis Group
Theta Borealis Sector is dominated by the Borealis Group, a very large cluster of stars containing an unusually high number of stellar giants.
- It is an astrographic feature visible across the whole of Charted Space.
- It is centered on the supergiant star Theta Borealis.
- The cluster lies close to the coreward edge of the Great Rift.
Significant Stars
The brightest stars in the group are called the Borealean Stars. They include:
- Theta Borealis: A7 Ia Supergiant, Luminosity: 73,000 sols.
- Sigma Borealis: M9 II Bright Giant, Luminosity: 16,200 sols.
- Tau Borealis: M9 II Bright Giant, Luminosity: 16,200 sols.
- Epsilon Borealis: M7 II Bright Giant, Luminosity: 15,550 sols.
- Zeta Borealis: M5 II Bright Giant, Luminosity: 14,900 sols.
- Mu Borealis: M5 II Bright Giant, Luminosity: 14,900 sols.
- Kappa Borealis: A3 Ib Supergiant, Luminosity: 13,000 sols.
The major stars of the cluster are surrounded by more than sixty other giant and subgiant stars, some almost as bright as the named giants, as well as numerous main sequence stars and white dwarfs.
- The cluster has higher than normal concentrations of gas and dust within it, largely consisting of material thrown off by the stars.
- This gas and dust reflects the intense light of the stars and gives the vast feature a diffuse glow.
The skies within the region are spectacular. Some of the brighter stars can be seen from the surfaces of worlds during daylight hours.
Many of the stars are active objects, experiencing violent flare activity and producing a lot of EM noise across the spectrum.
- The background interference is significant - sensor operations and communications can be seriously hampered by signals originating parsecs away.
- Levels of interference vary periodically.
- Areas of the cluster may contain clouds of matter thrown off by stellar activity.
- Radiation Levels may be significantly raised on worlds within the cluster.
Many of these gigantic, turbulent stars are destinations on the Korsumug Main.
Muravia Cluster
The Muravia Cluster is a small cluster of stars within the larger Borealis Group.
- It lies across parts of Persiphus Subsector, Ventura Subsector, Borealis Kantel Subsector, and Jauhaux Subsector.
- The supergiant star Theta Borealis lies on its trailing edge.
- It is considered likely to be the next major target of Korsumug aggression.
Rifts & Voids[edit]
The highest tech level commonly encountered out This Far Along (spinward of the Third Imperium) is TL–12, though a few worlds are more advanced.
- This level of technology allows the routine use of up to Jump-3 drives.
- Traditionally, areas that cannot be routinely crossed by Jump-3-capable vessels are denoted as rift regions.

Thetan Rift
The Thetan Rift is a large area of lower stellar density lying within the spinward-coreward quadrant of the Sector. It is composed of two separate regions:
- The Thetan Rift, measuring around 5 parsecs coreward-rimward by around 9 parsecs spinward-trailing and extending into Astron Sector.
- The Zephor Void, measuring around 4 parsecs coreward-rimward by around 3 parsecs spinward-trailing.
- The Korsumug Gate marks its trailing edge.
Thetan Void
The Thetan Void is a large area of lower stellar density lying within the coreward-trailing quadrant of the sector.
- It measures around 7 parsecs coreward-rimward by around 11 parsecs spinward-trailing.
- The Korsumug Gate marks its spinward edge.
The Great Rift
The rimward edge of the sector lies adjacent to the Great Rift, the great expanse of empty space dividing the Imperial core from those regions lying "Behind the Claw".
- It is a vast impassable barrier.
- It is studded with space-time anomalies.
Other Astrographic Features[edit]
Uncharted Anomaly[edit]
The "Enigma of Theta Borealis" [1] is a mysterious astrographic feature.
- It is believed to be an uncharted space-time anomaly
- Its precise location, nature, and characteristics remain unknown.
- It is believed to lie across parts of Monway Subsector and Banderhue Subsector.
Stellar Distribution[edit]
A basic map showing the distribution and size of stars within Theta Borealis Sector.
- 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).
- The two distinctive circular clusters of giant stars that make up the Borealis
Group can be clearly distinguished, with Kappa B (to coreward) and Theta B
(to rimward) at their respective centers.
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 sector and far beyond.
