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.
