Osma’s arrest of Eisenhorn
Lord Osma arrested Eisenhorn as Extremis Diabolus when Ordo Malleus pressure finally caught the radical’s paper trail. Thracian Primaris supplied the institutional stage even when the warrants smelled of Cadia’s wider Malleus politics. Eisenhorn’s friends and enemies watched the same desk decide how far a hero could fall. The arrest did not end the work. It renamed it.
