Dark Imperium (Pb)

Darkness descends across the galaxy as Cadia crumbles under Chaos's relentless assault. The Great Rift tears reality asunder, unleashing warp-spawned horrors and ancient terrors upon an empire teetering on the brink. Yet salvation stirs—a primarch awakens from millennia of slumber, and the Ultramarines rise anew to answer his call.

From the depths of stasis emerges Roboute Guilliman, the Emperor's son, bearing the fury of a reborn Ultramarines Legion. His return ignites a crusade of unprecedented scale—a desperate bid to reclaim the Imperium from the encroaching void and restore what was lost to darkness.

Yet the enemy masses as never before. From the Scourge Stars descends Nurgle's plague-ridden horde, their gaze fixed upon Macragge itself. Guilliman must race to Ultramar to face the Death Guard and confront Mortarion—his own brother, now twisted by the corruption of Chaos.
