Grand Master of Assassins
He is never seen by ordinary members of the Adeptus Terra, but rumoured to have personal access to the Emperor himself. His loyalty to the Emperor must be beyond doubt, for he single-handedly controls an organisation that could feasibly topple the Imperium should he so wish. It seems that he is chosen from among the directors of the temples. The Grand Master is always one of the High Lords of Terra, which ensures all Grand Masters have a say in the future of the Imperium.
The first Grand Master was Malcador the Sigillite, regent of Terra. In 546.M32, the position was held by Drakan Vangorich who was responsible for the events of The Beheading where he assassinated all the members of the High Lords of Terra, after which he escaped to an Assassinorum temple in hiding. A retribution force of Space Marines was dispatched who battled numerous assassins with a single Astartes succeeding in surviving to eliminate the traitorous Grand Master.
