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 tech-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 Traitor faction of the Mechanicum loyal to the Warmaster Horus later called the "Dark Mechanicum."
The Mechanicus acknowledge the Emperor of Mankind as the ruler of the Imperium of Man, but not the religious truth of the Imperial Cult or the Ecclesiarchy, and are granted an unusual amount of political and religious autonomy within the Imperium's structure, a role protected by the ancient Treaty of Mars. The Mechanicus essentially maintains an empire-within-an-empire in Imperial space, and its interests usually, but not always, coincide with those of the wider Imperium.
Instead of the Imperial Creed, the servants of the Mechanicus follow their own dark and mysterious scriptures and worship the strange deity they call the Machine God or the "Omnissiah."
As part of this faith, the Adeptus Mechanicus believes knowledge is the true manifestation of divinity in the universe, and all creatures and artefacts that embody knowledge are holy because of it. The Emperor is the supreme object of worship for the servants of the Mechanicus, for He is the living avatar of the Machine God that is the Omnissiah.
The Emperor was recognised by the ancient Mechanicum as the fulfillment of the prophecy of the coming of the Omnissiah because He comprehends so much, and understands more about the true nature of reality than any other being in existence.
The Tech-priests of the Adeptus Mechanicus also regard organic flesh as weak and view the removal and replacement of biological tissue with mechanical, bionic parts as sacred. Most elder Tech-priests have few organic parts left and eventually become more machine than man.
The Adeptus Mechanicus is based on Mars, the very first Forge World of the Imperium, and they are the sole rulers of the Red Planet. They provide the technical and scientific experts of the Imperium and field armies of massive Titans, Questor Mechanicus Knights, Electro-priests, Skitarii and Combat Servitors.

"There is no truth in flesh, only betrayal." "There is no strength in flesh, only weakness." "There is no constancy in flesh, only decay." "There is no certainty in flesh but death." — Credo Omnissiah
