The Dark Apostle is a high priest of the Ruinous Powers, a fanatical preacher who leads the warriors of Chaos in worship and war alike. Bearing an ornate crozius and cloaked in profane iconography, he is the spiritual heart of a warband, exhorting his brethren to ever greater atrocities in the name of the Dark Gods.
Through thunderous sermons and blasphemous rites, the Dark Apostle stokes the zeal of his followers until they fight with the reckless fury of true believers. He is versed in the dark liturgies that can call down the favour of the gods, binding the loyalty of his warriors and unsettling the resolve of the foe. In battle he wades forward at the fore, his crozius wreathed in unholy power, an unshakable icon of faith made manifest.
Within the ranks of the Chaos Space Marines, the Dark Apostle wields authority that rivals that of any warlord, for he speaks with the voice of the gods themselves. Attended by cowled Dark Disciples, he is both shepherd and executioner, guiding the damned along the ruinous path and consigning the faithless to a well-deserved doom.
