The serene skies of Ultramar shatter as Roboute Guilliman, blind to the Heresy’s shadow, gathers his Ultramarines against the Veridian threat. But the true enemy strikes from the stars: Word Bearers, once allies, unleash orbital hellfire upon Calth. Fleets burn, legions scatter, and betrayal crystallizes into Lorgar’s vengeance. As daemons pour forth and World Eaters join the fray, the Ultramarines are trapped in a brutal stalemate, fighting not just for survival, but to prove that even in the face of absolute despair, they know no fear.
