953.M30.
Colonid Sector, Soshio Star Strait, 4.13 light-years from the Greer Abyss.
The Ramillies-class Star Fortress Casteldeg guarded the mouth of the strait.
Any large-scale Ork tide that wanted to break into the Colonid Sector had to pass through the Soshio Star Strait.
The other regions were either blocked by Warp Storms or choked with chaotic asteroid belts. Only scattered Ork vessels could pass through them, posing no great threat.
The Soshio Star Strait was the only route by which the Greer Abyss Orks could move on a massive scale. Hold this place, and the Orks would never truly threaten the Colonid Sector.
In the nearly century since Casteldeg had been deployed, the majestic Void Bastion had shattered the Ork tides surging out of the abyss again and again.
A shrill alarm suddenly rang out through the central district of the Ramillies-class Star Fortress.
Gomez, a Librarian of the Sixth Legion and a divination Psyker, reviewed the tactical data inside his helm.
He strode to the divination table, lit the incense, and pressed his hand to the crystal ball.
Nine seconds later, the crystal ball still gave no response.
Gomez then ascended into the third layer of Magnus's Mindset, freeing his body of light from his flesh.
He looked down on the Auxilia's pale-red will to fight and their deep-black fear.
And on his battle-brothers' proud pale-red fighting spirit, and their blue, rational order.
The divination Psyker loosened the locks on his mind and let his thoughts drift.
He wandered aimlessly through the mist, seeking that thread.
As his body of light trekked onward, it gradually dimmed, and Gomez began to feel weary.
He gathered in his thoughts and let his body of light fall back into his flesh.
Gomez stood silently for several seconds before opening the vox.
