Partagaz was a human male who served the Imperial Security Bureau as a major. He led the ISB board in the ISB Central Office on the Imperial capital planet of Coruscant and concerned himself with identifying unrest long before it escalated into a threat to Imperial safety. Partagaz frequently questioned his subordinates on their reports, and during one ISB board session, one subordinate, Blevin, shared information about an ambush on Ferrix. Shortly after, Partagaz mediated a conflict between Blevin and lieutenant Dedra Meero, who had requested the raw data of the Ferrix incident, as she believed there was an organized rebel effort based on the theft of Imperial devices.

Not long after, a rebel infiltration team stole an Imperial payroll from the Aldhani garrison. In the wake of this attack, the Empire instigated the Public Order Resentencing Directive and gave the ISB the lead going forward. Still obsessed over the Ferrix incident, Meero managed to convince Partagaz to reassign the sector to her, and the ISB began to coordinate its efforts to identify the «Axis» of the rebels, who, unbeknownst to the Bureau, was Luthen Rael.
