Kahlenite Chain

On the eastern fringe of the Segmentum Pacificus lies the ancient and obscure Roteus sector, near the shifting and dangerous Warp currents between the Siren's Storm and Vortex of Despair (which can be found on maps of the Cicatrix Maledictum), there are a string of three nearby star systems.

These three systems, Koteal, Alovus, and Rokan, are collectively known as The Kahlenite Chain, and were all administered from the Sector seat on the Hive World of Kahlen. The sector has been extensively inhabited by Humans since the Dark Age of Technology (some dubious ancient records on Kahlen suggest the region was first settled around M21), and nearly all were brought into the Imperium during the Great Crusade Era.

There was limited fighting in the region during the Heresy, and a number of Xenos threats over the M30-40 eons, but on the whole the region has been remarkably stable, until the Cicatrix Maledictum broke apart the Galaxy.

The Siren's Storm and Vortex of Despair both grew and shifted, the horrible glowing arc of the Cicatrix appeared in the skies, and communication and travel through the Warp were blocked for a number of years. A few hysterical communications were recieved by neighboring sectors, but nothing coherent enough to mobilize serious aid, or to fully understand the nature of the problems. It sounds much like the same problems happening all over the Imperium.

The Kahlenite chain is old and ultimately strategically unimportant, and so the limited Imperium resources in the Segmentum all went elsewhere, as the Imperium is full of more urgent and more important problems, and crises more easily understood and fought.

Finally, the warp storms have receded, and a small fleet of Black Templars are returning to the region to restore order. Initial reports suggest that Heretic Astartes have toppled the sector seat on Kahlen, but that several planets in the chain have held out and remained loyal to the Emperor.

Median Warp transit times:

Koteal to Alovus:  5 days subjective,  23 days Imperial Solar Calendar time

Alovus to Rokan:   4 days subjective,  17 days Imperial Solar Calendar time

Current warp conditions are mostly clear, after having been turbulent and chaotic for several years. The Astronomicon is still partly obscured by the Siren's Storm, by now provides enough of a beacon to make inter-system transit possible. Exact exit locations may still be unreliable due to the obfuscation.

Astropathic communication is possible again, but often garbled or unclear due to interference, and many astropath nodes in the chain are unresponsive.
