The Adeptus Mechanicus are the fanatical worshippers of the Machine God of Mars. For thousands of years the robed priests of the Machine Cult have presided over the fabrication, maintenance, and preservation of Humanity’s surviving technological wonders with reverence and ritual. Led by Tech-Priests whose weak organic flesh has been replaced with metallic augmentations, their armies fight to defend forge worlds and strike out across the galaxy in search of ancient archeotech.

Among the Machine Cult's ranks are cohorts of obedient cybernetic soldiers, lumbering warrior robots, and battle servitors. They bear an array of esoteric weapons, capable of annihilating foes in volleys of irradiated ammunition or incinerating them with torrents of searing energy. Those who seek to sabotage the divine works of the Omnissiah must face the might of this merciless mechanical war machine, devoid of both pity and remorse.
