Forces of the Emperor

Outside the loyalist Space Marine Legions and the Cult Mechanicum, the Emperor wields forces which are loyal only to him. The Legio Custodes guard the Emperor's person, while the Sisters of Silence stand watch over the Black Ships. The Solar Auxilia are the elite spearhead of the Imperial Army, exemplars of mortal soldiery, while the Divisio Assassinorum is the Emperor's culling blade, aimed at the neck of any foolish enough to imperil his grand dream of Unity.
