Astron Voids

The Astron Voids are an astrographic feature lying across four subsectors located within Astron Sector.

• They are rift areas of low stellar density.
• They are a barrier to interstellar travel.

Description (Specifications)

The Astron Voids are connected areas of lower stellar density lying within the rimward-trailing quadrant of Astron Sector.

• Other large rifts in the region include the Longer Void to spinward and the Hudson Expanse to coreward.

What determines an area as a rift is 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.
• Locally, areas that cannot be crossed by Jump-3-capable vessels are denoted as rift regions.
• The nature and borders of a rift may be determined by other criteria in different regions.

The Voids are considered to consist of three distinct regions:

• The Great Astron Void, measuring around 5 parsecs coreward-rimward by around 13 parsecs spinward-trailing.
• The Lagoon Void, measuring around 4 parsecs coreward-rimward by around 7 parsecs spinward-trailing.
• The Sagar, a separate void region measuring around 2 parsecs coreward-rimward by around 4 parsecs spinward-trailing.

History & Background (Dossier)

The Astron Voids are desolate and lonely places, their dark and empty cores fringed by unpopulated, untamed wilderness systems.

• A few deep-frozen rogue worlds may lie within their boundaries.

The Voids prevent routine travel by vessels with less than Jump-4 drives.

• They form a natural obstacle to exploration and exploitation of the region.

The Three Sisters are a group of distinctive orange giant stars that are associated with the Astron Voids.

• The three stars lie at the rimward-trailing corner of Astron Sector.
• They can be seen from all across the sector and far beyond.

Historical Data

The Voids were originally charted during the 300s and 400s, during the Imperial First Survey.

Timeline

• ca -1900: The first human explorers are active in the region (Terrans of the Rule of Man).
• 300-420: The Imperial First Survey charts the region.
• 420: The region is officially named.
• 995-1065: The Second Survey charts the region.
