• Cawl examined the Flesh Tearers' surgery data and recognized the Muscle Coil, Belisarian Furnace, and Magnificat Organ Regulation System from his Primaris procedure.
• Alpha Primus confirmed that Romulus and the others had replicated and revised the procedure in less than half a year, removing its Warp component and distributing detailed manuals to the Chapters.
