The Adeptus Ministorum
To countless billions, the Emperor is nothing less than a god to whom they devote their entire
lives. Over the aeons, this faith has spawned a vast and powerful organisation devoted to His worship—the Adeptus Ministorum, more often known as the Ecclesiarchy, after its chief high priest, the Ecclesiarch. The Adeptus Ministorum is a very powerful organisation with its own crusading armies in the form of the Adepta Sororitas.
