Master executes prison coup

The Master orchestrates a brutal two-phase takeover of Stangmoor Prison, leveraging deception and lethal force to seize control. Disguised as Professor Keller, he first manipulates Mailer into compliance by promising gas masks and weapons stored in his car, ensuring Mailer’s cooperation in the assault. The Master’s calculated instructions—‘I'm expecting a visitor’—mask his true intentions, maintaining the illusion of normalcy while preparing for violence. When the moment arrives, the Master and Mailer don gas masks and deploy gas grenades, incapacitating the officers guarding the cell. As the Governor attempts to trigger the alarm, Mailer executes him in cold blood, then shoots two additional officers rushing to the locked gate. The Master’s cold efficiency and Mailer’s ruthless compliance underscore the escalation of the Master’s plan: deception alone is no longer sufficient. This violent coup not only secures the prison as a staging ground for his nuclear missile heist but also demonstrates his willingness to eliminate obstacles—human or otherwise—without hesitation. The event marks a turning point, shifting the narrative from psychological manipulation to outright warfare, with Jo Grant and the remaining hostages now trapped in a facility under the Master’s absolute control.

Who Was There

Characters present in this moment

4
Mailer
primary

Calculating and detached, with a predatory focus on eliminating threats to the Master’s objectives. His actions suggest a thrill in the violence, but his primary motivation is survival and power—he knows the Master’s success means his own freedom or dominance.

Mailer, initially a reluctant but calculating inmate, fully embraces his role as the Master’s enforcer. He sits on the table with gas masks hidden behind his back, listening to the Master’s instructions before donning the mask and deploying gas grenades through the inspection hatch. When the Governor attempts to trigger the alarm, Mailer executes him in cold blood with a single shot to the back, then turns his gun on two officers rushing to the locked gate, eliminating them without hesitation. His actions are precise, ruthless, and devoid of remorse, reflecting his transformation from a defiant prisoner to a willing executioner in the Master’s coup.

Goals in this moment
  • Secure the prison for the Master’s larger plan by eliminating opposition (Governor, officers).
  • Demonstrate his loyalty to the Master to ensure his own position of power in the new hierarchy.
Active beliefs
  • The Master’s promises of weapons and freedom are worth killing for.
  • The prison’s authority figures are obstacles that must be removed for his survival.
Character traits
Ruthless Obedient to authority (when it serves his interests) Cold-blooded Efficient under pressure Loyal to the Master’s plan
Follow Mailer's journey

Coldly triumphant, with a sense of inevitability. He is in his element—controlling chaos, turning enemies into tools, and advancing his grand scheme without direct exposure. There is no hesitation in his actions; he views the violence as a necessary means to an end, and the deaths of the Governor and officers as collateral damage in his larger game.

The Master, operating under the guise of Professor Keller, meticulously orchestrates the prison coup with surgical precision. He begins by manipulating Mailer with promises of gas masks and weapons, ensuring his cooperation while maintaining the illusion of normalcy. When the moment arrives, he and Mailer don gas masks and deploy gas grenades through the inspection hatch, incapacitating the guards outside the cell. His calm demeanor masks his true intentions—he is not merely escaping, but seizing control of Stangmoor as a staging ground for his nuclear missile heist. As Mailer executes the Governor and officers, the Master observes with detached satisfaction, his plan unfolding exactly as intended.

Goals in this moment
  • Seize control of Stangmoor Prison to use it as a base for his nuclear missile heist.
  • Eliminate institutional authority (Governor, officers) to prevent interference with his plans.
Active beliefs
  • Human life is expendable if it serves his objectives.
  • Deception and violence are the most effective tools for achieving his goals.
Character traits
Manipulative Strategic Calculating Ruthless (willing to use others as pawns) Charismatic (when necessary to deceive)
Follow The Master's journey
Governor
primary

Panicked and urgent, driven by the instinct to restore order. His final moments are defined by a desperate attempt to sound the alarm, a futile gesture that underscores the prison’s sudden descent into lawlessness. There is no time for fear—only the grim realization that he has failed in his duty.

The Governor, the highest-ranking authority in Stangmoor Prison, is caught off-guard by the Master’s ambush. As the gas grenades incapacitate the guards, he rushes to the short staircase leading to the alarm, desperate to sound the alert. However, Mailer—acting on the Master’s unspoken orders—shoots him in the back before he can trigger the alarm. The Governor’s death is sudden and brutal, marking the final loss of institutional control over the prison. His body collapses at the top of the staircase, a symbol of the prison’s fallen authority.

Goals in this moment
  • Sound the alarm to alert UNIT or external authorities to the riot.
  • Regain control of the prison by any means necessary.
Active beliefs
  • The prison’s security protocols can still contain the threat (a belief that is shattered by the Master’s violence).
  • His authority as Governor is absolute (until it is violently overturned).
Character traits
Reactive under pressure Duty-driven (even in the face of chaos) Vulnerable to ambush Symbol of institutional power (now broken)
Follow Governor's journey
Supporting 1

Unaware and compliant until the moment of attack. His emotional state shifts from routine professionalism to sudden, disorienting panic as the gas fills the air, though his incapacitation is too rapid for him to process fear or resistance.

The Stangmoor Prison Guard, unsuspecting and duty-bound, opens the inspection hatch of the Master’s cell in response to a knock. Before he can react, the Master and Mailer deploy gas grenades through the hatch, incapacitating him instantly. His role in the event is passive—he is a victim of the Master’s ambush, his actions limited to the brief moment of opening the hatch before being overwhelmed by the gas. His incapacitation is swift and silent, serving as the first casualty in the Master’s violent takeover.

Goals in this moment
  • None (his actions are reactive to the Master’s deception).
  • Maintain prison security (a goal that is immediately undermined by the Master’s ambush).
Active beliefs
  • The prison is secure, and the Master is a harmless inmate.
  • Following protocol will ensure safety (a belief that is fatally flawed).

Duty-bound Unsuspecting Vulnerable to deception Quick to follow protocol (even in dangerous situations)

Master's Gas Grenades

The Master’s gas grenades are the catalyst for the violent coup, serving as both a weapon and a tool of deception. Hidden behind their backs, the Master and Mailer deploy them through the inspection hatch of the cell door, filling the corridor with dense, incapacitating fumes. The grenades neutralize the guards outside the cell instantly, creating the chaos needed for Mailer to execute the Governor and officers. Their deployment is swift and precise, reflecting the Master’s preparedness and ruthless efficiency. The gas masks worn by the Master and Mailer ensure their immunity to the grenades’ effects, allowing them to advance unscathed while their enemies fall.

Before: Stored in the Master’s briefcase, compact and ready for deployment. Their existence is initially concealed from Mailer, who is promised additional grenades and weapons from the Master’s car as an incentive for cooperation.
After: Expended, with their residual fumes lingering in the corridor. The grenades have fulfilled their purpose—incapacitating the guards and facilitating the Master’s takeover of the prison. Their use marks a permanent shift in the power dynamics of Stangmoor, from institutional control to the Master’s domination.
Master's Gas Masks

The gas masks are critical to the Master’s plan, ensuring his and Mailer’s survival during the gas grenade attack. Worn behind their backs initially, they are donned just before the grenades are deployed, sealing over their faces and filtering out the incapacitating fumes. This allows the Master and Mailer to move freely through the choking haze, executing the Governor and officers without being affected by their own weapon. The masks symbolize the Master’s foresight—he anticipated the need for such protection and used it as both a tool and a bargaining chip to secure Mailer’s loyalty. Their effectiveness is evident as the guards collapse around them, helpless and gasping.

After: Worn and functional, having fulfilled their protective role. …
Before: Hidden behind the Master and Mailer’s backs, ready to be donned at the moment of attack. Their presence is a secret known only to the Master, adding to the element of surprise.
After: Worn and functional, having fulfilled their protective role. They remain on the Master and Mailer as they advance through the prison, now symbols of their dominance over the incapacitated guards and the fallen Governor.
Stangmoor Prison Cell Block Gate

The Stangmoor Prison Locked Gate serves as the next barrier in the Master and Mailer’s path, but it is quickly neutralized. As the alarm bells fail to sound, two officers rush toward the gate, only to be gunned down by Mailer before they can reach it. The gate, a heavy steel barrier designed to contain inmates and outsiders, becomes another casualty of the Master’s coup. Its locked status is irrelevant—Mailer’s bullets ensure that no reinforcements can pass through, solidifying the Master’s control over the cell block. The gate’s clanging under the riot’s chaos is a futile sound, drowned out by the gunfire and the Master’s triumph.

Before: Locked and secure, a standard security measure in …

Before: Locked and secure, a standard security measure in the prison’s layout. It is intended to prevent unauthorized access to the cell block, but its purpose is undermined by the Master’s violence.
After: Unlocked and breached, with the bodies of the officers lying nearby. The gate is no longer a barrier—it is a symbol of the prison’s compromised security, now under the Master’s dominion.
Stangmoor Prison Cell Short Staircase

The short staircase leading to the alarm switch becomes a stage for the Governor’s final, futile act of defiance. As the gas grenades incapacitate the guards, the Governor sprints up the stairs, his hand outstretched toward the alarm. However, Mailer—acting on the Master’s unspoken orders—shoots him in the back before he can trigger it. The staircase, a symbol of the prison’s hierarchy and the Governor’s authority, is where his power is violently extinguished. The Governor’s body collapses at the top, a grim reminder of the prison’s new order. The staircase’s role in the event is dual: it is both a path to potential salvation (the alarm) and a site of execution, marking the transition from institutional control to the Master’s reign.

Before: A functional part of the prison’s infrastructure, leading …
After: Stained with the Governor’s blood, now a monument …
Before: A functional part of the prison’s infrastructure, leading to the alarm switch. It is a symbol of the Governor’s authority and the prison’s ability to respond to crises.
After: Stained with the Governor’s blood, now a monument to the Master’s violence. The staircase’s purpose has been perverted—it is no longer a path to safety but a reminder of the prison’s fallen leadership.
Stangmoor Prison Emergency Alarm Bells (Prison-Wide System)

The Stangmoor Prison Alarm Bells, though never activated in this event, loom as a critical failed opportunity. As the Governor rushes to the short staircase leading to the alarm switch, Mailer shoots him in the back, preventing him from sounding the alert. The bells’ silence is deafening—it signifies the prison’s inability to call for help, leaving Jo Grant and the remaining hostages trapped in a facility now under the Master’s control. The alarm’s potential activation is a fleeting hope, crushed by Mailer’s ruthless efficiency. The bells’ absence of sound becomes a narrative device, emphasizing the prison’s isolation and the Master’s absolute dominance over the situation.

Before: Functional and ready to be triggered, representing the …
After: Untriggered and silent, a symbol of the prison’s …
Before: Functional and ready to be triggered, representing the prison’s last line of defense against the riot. The Governor’s attempt to reach them is a desperate bid to restore order.
After: Untriggered and silent, a symbol of the prison’s fallen authority. The alarm’s failure to sound underscores the Master’s success in neutralizing institutional resistance, leaving the prison and its occupants at his mercy.
Stangmoor Prison Master's Cell Door (with Inspection Hatch)

The Stangmoor Prison Cell Inspection Hatch is the critical weak point that enables the Master’s ambush. When the Master knocks on the cell door, an officer slides open the hatch to investigate, creating an opportunity for the Master and Mailer to deploy their gas grenades. The hatch is small but large enough to allow the grenades to be thrown through, filling the corridor outside with incapacitating fumes. Its design—intended for brief communication between inmates and guards—becomes the instrument of the guards’ downfall. The hatch is left open after the attack, a silent testament to the prison’s compromised security and the Master’s cunning use of its own infrastructure against it.

Before: Closed and locked, a standard security feature of …

Before: Closed and locked, a standard security feature of the cell door. It is used routinely for inspections and communication, but its purpose is subverted by the Master’s deception.
After: Open and unused, with the gas grenades’ residue lingering around it. The hatch is no longer a tool for communication but a symbol of the prison’s vulnerability, exploited by the Master to launch his coup.

HM Prison Stangmoor

The Stangmoor Prison Cell Block is the epicenter of the Master’s violent coup, a space where institutional authority is shattered and chaos reigns. Bars line the grimy walls, once symbols of containment, now witnesses to the prison’s descent into lawlessness. Inmates shove hostages like Jo Grant up iron stairs at gunpoint, while guards encircle the wing in a futile attempt to maintain order. The cell block becomes a battleground as gas grenades choke the air, gunfire echoes, and the Governor is executed on the short staircase. The atmosphere is one of controlled chaos—Mailer’s ruthless compliance with the Master’s orders drives the frenzy, while Jo disarms him in a brief moment of resistance. The block’s layout, with its iron stairs and locked gates, is both a practical obstacle and a symbolic representation of the prison’s crumbling hierarchy.
