For too long, the Emperor's Children have been denied their birthright. Once a legion of perfection, they now exist as fractured warbands, driven by excess and ambition, scouring world after world in a hollow pursuit of glory. That age of aimless ruin is at an end.

Fulgrim – ascended Primarch of the III Legion, the Perfect Son, Emperor-in-Waiting – issues a singular command to his scattered warriors: conquer the Imperial world of Crucible and deliver the head of the Black Templars champion charged with its defence.

What should be a swift and brutal assault instead becomes a grinding siege. As the world burns and victory hangs in the balance, Fulgrim’s true designs begin to surface. The Emperor’s Children are forced to turn not only on their enemies, but on one another, as rival champions vie for favour and survival.

With loyalty fraying and excess consuming them from within, the legionnaires must confront an uncomfortable truth: what must be sacrificed to earn Fulgrim’s approval – and what will remain of them once the war is over?
