"These men are my bodyguards, their lives forfeit to the guarantee of my physical safety. Of their loyalty to me there shall be no question nor doubt. I, and I alone, shall have the authority to stand in judgement over them. No other commander shall they have in battle nor in service. None shall bar them from me and none shall hamper or stall their mission. So it is decreed!"- Ancient declaration made by the Emperor of Mankind during the Age of Strife
The Adeptus Custodes, known as the Legio Custodes until after the Horus Heresy, is the Imperial Adepta responsible for guarding the Imperial Palace and the physical body of the Emperor of Mankind. They are a group of 10,000 genetically-engineered superhumans who are even more potent in combat than the Adeptus Astartes and who serve as the Emperor's personal guardians and praetorian bodyguard. Since the Emperor's internment in the Golden Throne following the Horus Heresy ten millennia ago, they have taken a far more limited role in the Imperium of Man. They almost never leave Terra and only very rarely leave the Imperial Palace. Only the Adeptus Custodes decide who may enter the Sanctum Imperialis of the Emperor at the heart of the Inner Palace, and when they may do so.

- When on duty uniform must be worn and Custodians are expected to be silent unless spoken to by the Chief Centurion or the Emperor.

- Always follow your orders to the letter.
