Inquisitor Soldevan's mentor and inquisitor when Soldevan was an Interrogator. They disagree on tactics; Rykehus prefers to charge in, set up courts and punish swiftly. If that means some innocents are inadvertently hurt, they honour the Emperor with their sacrifice. Soldevan was apparently prevented from joining the Ordo Xenos because of Rykehus, and had to settle for Ordo Hereticus. Rykehus was on a witchhunt (Jacket) in the Coscarla Division, when he and his cadre crossed paths with Soldevan's acolytes.
He is many centuries old, but rejuve-jobs have kept him in his early fifties. He has hawkish features and terrible violence dances in his eyes. His expressive mouth is usually smiling, even when smiting his enemies.
Alive: Last seen in Coscarla Division.
