The tranquil heavens of Ultramar rupture without warning. Roboute Guilliman, oblivious to the galaxy-wide heresy, has concentrated his Ultramarines to face the Veridian menace. The true threat, however, descends from the void: the Word Bearers, once sworn allies, rain orbital devastation upon Calth. Capital ships combust, battle formations disintegrate, and treachery hardens into Lorgar's final, brutal answer. As warp-spawned horrors spill from reality's wounds and the frothing World Eaters join the assault, the Ultramarines are caught in a vicious deadlock. They battle not merely for survival, but to affirm a core tenet of their being: that even confronting absolute ruin, they know no fear.
