The Grand Master of the Knights Teutonic is the supreme head of the Teutonic Order.
By 1191, Sibrand had become the first Grand Master of the newly-founded Knights Teutonic. In secret, he was also a member of the Knights Templar, subordinate to the Templar Grand Master Robert de Sablé. That year, Sibrand planned a blockade of the harbor in order to prevent King Richard from receiving aid from overseas once the Templars initiated their plan to usurp control of the Holy Land. However, Sibrand was assassinated by the Assassin Altaïr Ibn-La'Ahad on the orders of the Levantine Brotherhood leader Al Mualim on his own ship at the harbor of Acre.
