The Investigations division was a component of the Imperial Security Bureau of the Galactic Empire, tasked with utilizing intelligence to quell insurgent actions. Within the ISB, Kallus, an Agent, held positions in Investigations, Internal Affairs, and the Enforcement sections. Dedra Meero moved from Enforcement to Investigations, functioning as an ISB Supervisor on the ISB Board.
The Investigations department was initially referenced within canon through the publication, Star Wars: Absolutely Everything You Need to Know. Its initial on-screen depiction occurred in the Andor episode "Aldhani," although definitive confirmation that the ISB division depicted was Investigations did not emerge until the publication of Star Wars: Dawn of Rebellion: The Visual Guide. This guide verified Meero's transition to Investigations following her tenure in Enforcement; the episode "Aldhani" indicates Meero's previous service within Enforcement before her current assignment, thus confirming the branch's identity as Investigations when viewed in conjunction with Dawn of Rebellion.
