Lord Osma

Lord Osma was the Ordo Malleus lord who arrested Eisenhorn as Extremis Diabolus during the Cadia and Helican crisis in Malleus.

He treated Eisenhorn’s daemonhost bargains and radical toolkit as proof the hunter had crossed the line the Ordos exist to police. The arrest put institutional Malleus weight on a man already running from Quixos’s shadow and his own choices.

Cadia and Thracian Primaris mark the pressure. Osma remains the named warrant behind Eisenhorn’s Extremis branding, not a footnote in someone else’s interrogation.
