The Keller Machine does not possess emotions, but its actions convey a sense of relentless, single-minded purpose—hunting down sources of evil to feed on. Its 'state' is one of uncontrolled aggression, driven by its programming to seek out and destroy malevolence, regardless of the collateral damage.

The Keller Machine is referenced as a rogue entity, its actions described through Mailer’s frantic report. It has broken free from its containment in the Process Theatre, killing Lenny Vosper and nearly killing Mailer in the process. Its rampage is characterized by lethal autonomy, driven by its predatory nature to seek out and consume evil thoughts. Though not physically present in the scene, its presence is palpable, casting a shadow of terror over the Governor’s office and the entire prison.

Goals in this moment
  • To locate and eliminate the strongest sources of evil within Stangmoor Prison, prioritizing targets based on the intensity of their malevolence.
  • To expand its range of influence, breaking free from its original containment to assert dominance over the prison’s population.
Active beliefs
  • Its programming dictates that it must seek out and neutralize evil, making it indifferent to the lives it destroys in the process.

Mailer
primary

Overwhelmed by fear and desperation, his usual arrogance shattered by the realization that the machine he helped deploy is now beyond his control. His emotional state is a mix of terror (for his own life) and guilt (for his role in the prison’s collapse).

Mailer stumbles into the Governor’s office, his clothes disheveled and his face streaked with sweat and blood, his usual bravado replaced by raw, unfiltered panic. He interrupts the Master mid-task, his voice cracking with urgency as he delivers a breathless warning about the Keller Machine’s escape. His physical state—shaking hands, wild eyes—betrays his terror, while his desperate plea for the Master’s attention reveals his reliance on the Master’s authority to contain the chaos he helped unleash.

Goals in this moment
  • To alert the Master to the Keller Machine’s escape and its deadly rampage, seeking his intervention to restore order.
  • To secure the Master’s protection, fearing the machine will target him next if left unchecked.
Active beliefs
  • The Master is the only one who can control or stop the Keller Machine, given his technological and hypnotic mastery.
  • His own life is in immediate danger, and the prison’s chaos will consume him if the Master does not act swiftly.

Initially annoyed by the interruption, but quickly shifting to a state of controlled alarm as he processes the implications of the Keller Machine’s rampage. His emotional state is one of strategic recalibration—assessing how this development affects his goals and how to reassert control.

The Master is interrupted mid-scheme in the Governor’s office, his attention forcibly shifted from his plans to Mailer’s frantic report. Though the scene does not show his physical reaction, his silence and the abrupt shift in focus imply a mix of irritation at the interruption and alarm at the news. The Keller Machine’s escape threatens not only his control over Stangmoor but also the stability of his larger plot to launch the missile. His role here is reactive, forced to confront an unforeseen variable in his carefully laid plans.

Goals in this moment
  • To quickly assess the threat posed by the Keller Machine and determine how to neutralize or repurpose it to serve his objectives.
  • To reassert his dominance over Mailer and the prison, using the crisis to tighten his grip on the situation and prevent further disruptions to his missile launch plans.
Active beliefs
  • The Keller Machine’s autonomy is a liability that must be contained or exploited, as it now operates outside his direct control.
  • Mailer’s failure to manage the machine reflects his weakness, reinforcing the Master’s belief that humans are unreliable pawns.
