Adeptus Mechanicus

The Adeptus Mechanicus is the official Imperial name within the Adeptus Terra for the Cult Mechanicus or Cult of the Machine based on Mars which provides the Imperium with its scientists, engineers and technicians. The Adepts of the Mechanicus are the primary keepers of what is viewed as sacred wisdom, a privileged caste of Tech-priests who jealously guard the knowledge required to maintain and construct much of the Imperium’s advanced technology. In ancient times, before the current Age of the Imperium officially began following the end of the Horus Heresy, the Adeptus Mechanicus was instead called the Mechanicum. The Adeptus Mechanicus was formally separated from the larger Mechanicum of Mars by order of the Council of Terra in 012.M31. This occurred after the Red Planet had fallen to the control of the Hereteks who represented the Traitor faction of the Mechanicum.
