The Adeptus Mechanicus are the mysterious and insular tech-savants of the Imperium of Man. Obsessed with the sanctity and preservation of the machine, theirs is a dogma of stagnation. But there is one among them who still pursues innovation: Archmagos Dominus Belisarius Cawl.
In To Speak as One, Cawl sends his most trusted acolytes to an Inquisitorial fortress to acquire a xenos specimen. But when the Inquisition refuse to hand over their prisoner, the agents of Cawl are forced to take drastic action.
