A mix of anger, desperation, and denial, with a growing sense of isolation as his commands are ignored.

Brigade Leader Stewart enforces the lockdown with military precision, ordering security guards to prevent evacuations and clashing with Greg over the decision to stay. His rigid adherence to duty borders on delusion, as he insists on maintaining control even as the facility collapses around him. Stewart's defiance—'You still have a job to do here, Sutton!'—reveals his inability to accept the futility of his orders. His authority crumbles as the Doctor's warnings prove prophetic, and his final act of posting guards outside the building is a hollow gesture in the face of annihilation.

Goals in this moment
  • Maintain order and enforce the lockdown at all costs
  • Protect the regime's authority even in the face of disaster
Active beliefs
  • Duty and protocol are the only things that matter
  • Evacuation is an act of treason and cowardice

Central Control Integrated Systems (Drilling Mainframe and Monitoring Network)

The Central Control drilling mainframe, once a hub of monitoring and command, collapses entirely as systems fail. Its breakdown strips the team of their last means of oversight, leaving them blind to the escalating disaster. The mainframe's failure is both a practical and symbolic moment—the end of human control over the forces they unleashed. Its red displays flicker and die, mirroring the death of hope and the regime's authority.

British Government (Inferno Crisis Oversight)

The Government, though absent from the scene, looms as the ultimate authority that has abandoned the facility to its fate. Shaw reports that authorities have ordered an evacuation of non-essential personnel but expect the crisis to 'pass over,' a decision that hastens the disaster. The organization's power dynamics are defined by its detachment from the immediate crisis, its influence mechanisms—bureaucratic orders and distant logistical support—proving utterly inadequate. Their goals at this event are purely reactive: contain the fallout, maintain the illusion of control, and distance themselves from responsibility. The institutional impact is one of betrayal and neglect, as the government's inaction accelerates the collapse.

Brigade (Military and Security Forces under Brigade Leader Stewart)

The Military and Security Forces under Brigade Leader Stewart enforce the lockdown with rigid discipline, even as the facility collapses. Benton 2 rounds up the remaining guards to post outside Central Control, preventing evacuations and upholding Stewart's futile orders. Their actions reflect the regime's last gasp of control, a desperate attempt to maintain order amid chaos. The organization's power dynamics are defined by blind obedience to authority, even in the face of annihilation. Their influence mechanisms—military protocol, threats, and physical force—are rendered meaningless by the scale of the crisis, yet they persist in enforcing them.
