Malcador the Sigillite, also known as Malcador the Hero by decree of the Emperor of Mankind, was the First Lord of Terra, who served as essentially the Emperor’s Regent when He was away from Terra and the first Grand Master of Assassins during the Great Crusade and the Horus Heresy eras.
By the dawn of the 31st Millennium, Malcador was over 6,700 standard years old and could remember his date of birth to the second. His title of “Sigillite”, meaning “seal-bearer” in an ancient Terran language, was a measure of the esteem and trust the Emperor had in Malcador, for he was empowered to speak and act in the Emperor’s stead with the Emperor’s full authority wherever he went.
