Adeptus Administratum [BRDAA]

The Administratum is the administrative and bureaucratic division of the Adeptus Terra, consisting of untold billions of clerks, scribes and administrative staff constantly working to manage the Imperium at every level, from assembling war fleets to levying taxes. It is the largest of the departments comprising the Adeptus Terra - the mere administration of the Imperial Palace is estimated to involve over ten billion adepts.
