A Tech-priest, also spelled Tech-Priest or even tech-priest, is an adept of the Adeptus Mechanicus of the Imperium of Man who is generally responsible for maintaining all of the advanced technology of the Imperium, enlarging the Imperium’s stocks of technical knowledge and conducting what little new scientific research occurs within the Imperium since the end of the Horus Heresy. Tech-priests are members of the Cult Mechanicus, the Cult of the Machine, a priesthood which forms an ecclesiastical hierarchy of technicians, scientists, and religious leaders who believe that knowledge represents the only true divinity in the universe. The Tech-priests provide the rest of the Imperium with its equivalent to technicians, scientists and engineers.
