Mandragore Carrion

Mandragore Carrion is a Space Marine of the Emperor’s Children Traitor Legion, recorded as party to the Saruthi exchange for the Necroteuch. The Emperor’s Children are one of the nine Space Marine Legions that turned against the Emperor during the Horus Heresy, thereafter continuing as a warband tradition within the wider Imperium’s understanding of Chaos-aligned forces. Within the Eisenhorn chronicles, the name surfaces in connection with a transaction involving the Saruthi, a xenos species of note for their alien cognition and architecture, and the Necroteuch, a proscribed text held to carry heretical and Chaos-tainted knowledge.

Accounts place Carrion’s involvement at the periphery of the wider conspiracy that Inquisitor Gregor Eisenhorn investigates across the series, in which renegade scholars, heretical Inquisitorial elements, and outside intermediaries sought access to the Necroteuch through contact with the Saruthi. The presence of an Emperor’s Children Astartes at such an exchange is consistent with the Legion’s later association with forbidden lore and pacts extending beyond purely military ends. Further particulars of Carrion’s conduct during the exchange, including its outcome, are not fully attested in the record and are recounted with varying detail across secondary tellings of the episode.

Mandragore Carrion’s standing rests chiefly on this single documented association rather than on an extended campaign history. The figure nonetheless illustrates the broader pattern, recurrent in the Eisenhorn narrative, of Chaos-aligned Astartes acting as agents or brokers in the pursuit of proscribed knowledge, linking the military threat of the Traitor Legions to the subtler, information-driven conspiracies that the Inquisition is tasked with suppressing.
