Cheetham Subsector is Subsector A of Iphigenaia Sector.
- It lies within Charted Space.
- On some star charts it may be named Chasm Subsector.
Description (Specifications)[edit]
Cheetham Subsector is an unpopulated wilderness that rarely sees visitors.
- It is named for Xavier Cheetham, an explorer and media personality who disappeared in the area a century ago.
- The original name dates back to the Rule of Man, before the Long Night.
- The resources of the subsector are completely untapped.
Astrographic Features & Trade Routes: 1105[edit]
The following astrographic and commercial data has been determined regarding Cheetham Subsector:
- The subsector is a sparse stellar density region.
- The brightest star is the orange subgiant primary of the Utradis system.
- No trade routes are noted as crossing the region.
Stellar Distribution[edit]
A basic map showing the distribution and size of stars within Cheetham Subsector, right:
- 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]
One rift area lies within the subsector: the Idella Rift.
- It dominates almost the whole of the subsector.
A simple map showing rift regions within Cheetham Subsector, right:
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.
- This level of technology allows the routine use of up to Jump-3 drives.
- Areas that cannot be crossed by Jump-3-capable vessels are denoted as rifts.
Borealis Group[edit]
The Borealis Group can be seen as a bright, dense, noticeable grouping of stars in the skies to Spinward.
- It is a huge cluster of stars centered on the supergiant Theta Borealis.
- It is a distinctive astrographic feature that can be observed from all across Charted Space.
World Listing: 1105[edit]
Comprehensive Second Survey data for all worlds lying within Cheetham 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:
7 Worlds in the Cheetham Subsector
Note that some Second Survey data, though only 40 years old, may already be out of date.
- Verified updated data is constantly sought.
Subsector Summary: 1105[edit]
Note that this section is awaiting an AAB Internal Records update.
