Master disables Keller machine remotely

The Doctor, battling the Keller machine’s nightmare-inducing effects while attempting to sabotage it, finally succeeds in placing a protective coil on its core. As the Dalek oversees the activation, the Doctor triggers his sabotage, but the machine’s influence remains unstable. Outside the chamber, the Master—monitoring the situation—remotely shuts down the machine entirely, cutting off its evil-amplifying signal. This abrupt intervention temporarily neutralizes the machine’s hold over the Daleks’ annihilation orders, creating a fleeting window of opportunity. The Doctor, now free from the machine’s immediate psychic assault, removes his protective gear, signaling a shift in the power dynamic. The Master’s calculated move reveals his layered motives: he prioritizes control over the Daleks’ actions, even at the cost of disrupting his own plans. The moment underscores the precarious balance of power between the two Time Lords, as the Doctor’s sabotage and the Master’s intervention collide in a high-stakes tactical maneuver amid Stangmoor Prison’s escalating chaos.

Dalek
secondary

Frenzied and bloodthirsty, with its commands reflecting the Keller Machine’s amplification of its inherent hatred. The sudden silence after the shutdown leaves it disoriented but still primed for violence.

The Dalek, positioned outside the Process Theatre, screams orders of 'Exterminate! Annihilate! Destroy!' as it oversees the Keller Machine’s activation. Its aggressive and unstable state is amplified by the machine’s evil-influencing power, making it a volatile and dangerous force in the prison. The Master’s shutdown of the machine temporarily silences its commands, though its hostility remains palpable.

Goals in this moment
  • Obey the Master’s directives while under the Keller Machine’s influence, amplifying its destructive impulses.
  • Eliminate perceived threats, particularly the Doctor, as commanded by the machine’s psychic amplification.
Active beliefs
  • Destruction is the only solution to all conflicts, especially those involving the Doctor.
  • The Master’s control is absolute and must be followed without question.
