In the Dalek Control Room, Trantis—a desperate volunteer for the Time Destructor’s test—is forced into the chamber, his terror palpable as the machine fails to activate. The Black Dalek, realizing the taranium core provided by Chen is counterfeit, coldly declares the experiment a failure. As Trantis, believing he has survived, stumbles from the chamber, the Black Dalek orders his immediate extermination, demonstrating the Daleks’ absolute ruthlessness. Chen, witnessing the execution, is visibly shaken, his earlier bravado crumbling as he realizes the Daleks’ willingness to discard even their own collaborators. The moment forces Chen to confront the true nature of his alliance, shattering any remaining illusions about the Daleks’ ‘mercy’ and underscoring their manipulative brutality. The scene serves as a turning point for Chen, marking the beginning of his disillusionment and the Daleks’ escalating paranoia over the taranium deception.

The Black Dalek, supreme commander of the Dalek forces, glides menacingly across the control room to confront Chen after the Time Destructor fails. With clinical precision, it declares the taranium core counterfeit, accuses Chen of deception, and orders the immediate extermination of Trantis as he emerges from the chamber. The Black Dalek’s actions are a calculated display of power, reinforcing Dalek authority and the consequences of betrayal.

Trantis, a desperate volunteer for the Time Destructor test, is forced into the chamber by Daleks, his terror palpable as the machine fails to activate. Believing he has survived, he stumbles out—only to be immediately exterminated by the Black Dalek. Trantis’s execution serves as a brutal demonstration of Dalek logic: his life is expendable, and his fate is a warning to others.

primary

Horrified and disillusioned—Chen’s emotional state is one of crumbling confidence, replaced by a raw, exposed fear. His earlier arrogance gives way to a desperate attempt to shift blame, revealing his deep-seated vulnerability and the realization that the Daleks see him as expendable.

Mavic Chen, the Supreme Guardian of the Solar System, watches in horror as the Black Dalek exposes his counterfeit taranium core and orders Trantis’s execution. Initially defiant, Chen’s denial crumbles into desperation as he blames the Doctor for the deception, his earlier bravado replaced by visible shock. The Black Dalek’s accusation shatters Chen’s illusion of control, forcing him to confront the Daleks’ ruthlessness and the fragility of his alliance. He is left waiting in the control room, his power and authority diminished, as the Daleks prepare to send a time machine to Skaro.

Celation
secondary

Resigned and slightly amused by the Daleks’ failure, but ultimately indifferent to the outcome. Celation’s emotional state is one of detached observation, with a hint of relief at being dismissed from the volatile situation.

Celation, positioned in the observation area with Chen, watches the Time Destructor test unfold with detached skepticism. He questions Trantis’s role and the machine’s failure, but his involvement is peripheral—he is quickly dismissed by the Black Dalek and allowed to leave the control room. Celation’s departure underscores his marginalized position in the Dalek coalition, as the Black Dalek focuses solely on Chen’s betrayal and the immediate crisis at hand.

Goals in this moment
  • To observe the Time Destructor test and assess its viability, representing his faction’s interests.
  • To avoid being implicated in Chen’s deception, ensuring his own faction’s safety.
Active beliefs
  • The Daleks’ reliance on external allies like Chen is a strategic weakness, and their failures reflect poorly on their leadership.
  • His faction’s temporal technology is superior, and the Daleks’ setback may create an opportunity for greater influence.
Character traits

None—Daleks operate on cold logic, with no emotional response to Trantis’s execution or Chen’s betrayal. Their actions are purely functional, driven by the Black Dalek’s authority and the Daleks’ overarching goal of domination.

A generic Dalek soldier, acting under the Black Dalek’s direct command, forces Trantis into the Time Destructor chamber and later carries out his execution. The Dalek’s actions are mechanical and devoid of emotion, reflecting the Daleks’ collective hive-mind mentality. It confirms the taranium core’s failure, activates the Time Destructor, and obeys the Black Dalek’s order to exterminate Trantis without question. The Dalek’s role is that of an enforcer, ensuring the Black Dalek’s commands are executed with precision and efficiency.

Goals in this moment
  • To carry out the Black Dalek’s orders without deviation, ensuring the Time Destructor test proceeds as commanded.
  • To eliminate any perceived threats or failures, such as Trantis, to maintain Dalek supremacy.
Active beliefs
  • The Black Dalek’s commands must be followed absolutely, as they reflect the Daleks’ collective will.
  • Any deviation from Dalek protocol or failure in execution is unacceptable and must be corrected immediately.

The Time Destructor’s malfunction is a pivotal moment—it forces the Daleks to acknowledge their vulnerability and escalate their pursuit of authentic taranium from Skaro.
