Passax
Passax was a Magos in the Mechanicum during the Horus Heresy and was among those Loyalists who escaped to Terra during the Schism of Mars. Following their resettlement though, the Mechanicum Loyalists were left with no political power to wield, with the loss of Mars and the contention among them about who now led the Mechcanicum. The Imperium took advantage of this and would not heed the Mechanicum Loyalists' pleas to aid them in retaking Mars from the Traitors, but still insisted the Loyalists provide them with support against the Warmaster's forces. After this went on for sometime, Passax and Magos Gerantor approached the Mechanicum's Ambassador Vethorel, with their complaints and though she assured them she was doing everything she could to rectify the problem, they were left unconvinced any progress was being made. When the Imperium's War Council next met however, Vethorel made good on her promise and advanced the idea to create the Adeptus Mechanicus, which had the blessing of the Mechcanicum's nominal Fabricator General Zagreus Kane. If the Adeptus was established, it would make the Mechanicus a part of the Imperium, instead of the uneven partnership it now had with the Mechaniucm, and would clearly establish Kane as its leader; ending any doubt that he and not the Heretic Kelbor-Hal, truly led the Omnissiah's servants.[1]
While Vethorel's plan for the Adeptus Mechanicus was turned down by the War Council, the very idea of it made the Ambassador a traitor to many of the Loyalist Mechanicum on Terra. Among them was Passax and Gerantor, who feared that the creation of the Adeptus Mechanicus would make them slaves to the Imperium and they decided to assassinate Vethorel, to prevent it from occuring. After rallying others to their cause, they attacked the Ambassador during a gathering of the Mechanium Loyalists and would have succeeded in killing her, were it not for the intervention of the Princeps Bassanius of Legio Ignatum and Tevera of Legio Agravides. The Princeps had agreed with Vethorel's plan to create the Adeptus Mechanicus and with the aid of other Princeps and their Moderati, they saved Vethorel's life by killing Passax, Gerantor and their attacking followers.[1]
