|Department of Internal Operations|
|Flash Patch:||A cactus pierced by a knife|
The Department of Internal Operations was a PPC Department that went after Mary Sues that infiltrated HQ itself. That it even existed is not common knowledge — in theory, only the Flowers and members of the department itself knew about it — and all non-members were neuralysed on contact with it. It was headed by the Elm.
According to Peter Piper, if the DIO's existence were to have become common knowledge it would have caused a public outcry against the Board of Department Heads that would most likely have resulted in a second Reorganisation and the deaths of the DIO's members ("Nita, you were chosen in part because we knew that your reaction to this would not be too severe. Most agents are not like you. Especially among the older members, there's too much of the DIS about us. We would be dead if they knew about us, defences or no.").
The DIO was created as one of three new Security Departments (along with the DIA and the DES) in the wake of the Reorganisation and the exile of the DIS. It was located inside a maze of urple, wilver, bleen, and blello walls, laced with gravity distortions which all DIO agents learned to navigate blind. Even if this defence were somehow penetrated, Agent Justin Agent would have been waiting with his axe to stop any infiltration.
During the Swan's Egg Trilogy, the DIO came into contact with the PPC Board. This led Peter Piper to fall into a fit of insanity, during which he killed several Flowers, believing them to be secretly controlling the agents of the PPC. Due to this incident, the DIO was shut down, and its former agents separated.
