The massive Imperial fleet bore scars of battle across its hulls—charred impact craters, armor plating corroded by acidic slime, and breaches hastily sealed with welded repairs.

The Void Shield generators droned ceaselessly, their energy readings fluctuating wildly. Tech-Priests and servitors moved through narrow passageways and open repair decks, using spare parts and prayers to preserve the lives of these steel behemoths.

Every minor spatiotemporal disturbance made the ships' frames groan, reminding everyone just how devastating the destruction they had escaped had been.

The screen streamed immense quantities of data from the Battle of Stygia: the attack vectors of Tyranid bio-ships, energy discharge patterns, the frequency with which different unit types appeared and their mutation records, as well as loss reports and final combat logs for every Imperial combat unit.

Bloodshot from lack of rest, his eyes remained sharp. His fingers moved rapidly across the console, extracting, comparing, and archiving key information.

"But after encountering concentrated fire from our lance arrays, its mid-battle tactics clearly shifted. It concentrated its main force while using large numbers of smaller organisms as expendable fodder to drain our ammunition and energy.

"The interval between those tactical changes was far
