Kysnaros was an aloof, secretive, and inscrutable figure, even to other members of the Inquisition, which has secrecy and inscrutability as part of its mandate and daily operation. No reliable information is known of his past prior to his involvement in the First War for Armageddon campaign and the purge that followed. During that operation it was rumoured amongst the members of his Inquisitorial task force that he earned his rank and title through a number of successful small-scale Crusades and minor, street-level planetary purges. However, the rumours were likely untrue, as it takes centuries to build the powerful alliances and friendships an individual needs to ascend to the exalted rank of a Lord of the Inquisition.
