Thetan Rift

The Thetan Rift is an astrographic feature lying across parts of four subsectors within Theta Borealis Sector and Astron Sector.

• It is a rift area of low stellar density.
• It is a barrier to interstellar travel.

Description (Specifications)

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.
• The nature and borders of a rift may be determined by other criteria in different regions.

Astrography

The Thetan Rift is a large area of lower stellar density lying within the spinward-coreward quadrant of Theta Borealis Sector.

• Other large rifts in the region include the Thetan Void to trailing and the Great Rift to rimward.

The Rift is composed of two separate regions:

• The Thetan Rift, measuring around 5 parsecs coreward-rimward by around 9 parsecs spinward-trailing.
• The Zephor Void, measuring around 4 parsecs coreward-rimward by around 3 parsecs spinward-trailing.
• The Korsumug Gate marks its trailing edge.

History & Background (Dossier)

The Thetan Rift is a desolate and lonely place, empty of stars and uncrossable by most starships.

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

The Rift prevents routine travel by jump-5-capable vessels.

• It presents a significant obstacle to interstellar trade and commerce.
• It forms a natural defensive barrier against the Jaibok.

Historical Data

The Rift was originally charted during the 300s and 400s, during the Imperial First Survey.
