The Spymaster: In the Imperial governance, the people who sit on the Imperial Security Executive, the council that runs Imperial State Security, which is composed of the heads of the five directorates, the admirals in charge of the Shadow Fleet, its military intelligence counterpart, and certain others, whose identity is not available anywhere. It’s also unique on the organization chart in that the Executive reports directly to the Imperial Couple as well as to its nominal superiors in the Ministry of Harmonious Serenity.
Plenty of other organizations, of course, have their own – even before we get into competing governments.
