The Captain-General is the rank given to the commander of the Adeptus Custodes, the elite personal bodyguards of the Emperor who dwell within the Imperial Palace on Terra. As the highest authority within the Custodes, the Captain-General determines who may have access to the Emperor's body upon the Golden Throne and is the chief of security within the Imperial Palace. These two roles make the Captain-General of the Custodes an influential figure and often he is a member of the High Lords of Terra.[Needs Citation]
