Doctor and Bellal face city's sentient antibodies

The Doctor and Bellal reach the city's control room and devise a plan to disable its power by targeting the brain and nervous system. The Doctor assembles circuit boards to disrupt the city's defenses while Bellal warns of a new threat. Two bipedal entities begin forming in red-lit alcoves, revealing the city's self-defense mechanisms awakening to neutralize intruders. The Doctor recognizes these as antibodies and briefs Bellal on the escalating danger, setting the stage for a desperate effort to outmaneuver the city's evolving countermeasures before their foes can exploit the situation further. key_dialogue: [ "BELLAL: Look!

The Fourth Doctor
Science Officer
 primary

Concentrated determination masking underlying urgency to act before the antibodies fully form

The Doctor moves swiftly between the control room panels, assembling circuit boards with focused precision while observing the city’s escalating defenses. He remains calm but urgent, addressing Bellal with calm instructions despite the unfolding crisis.

Goals in this moment
  • • Disable the city’s power by targeting its brain and nervous system using the circuit boards
  • • Prevent the antibodies from completing their formation to avoid neutralization
Active beliefs
  • • Sentient cities prioritize defense against perceived threats, including visitors
  • • Direct intervention is necessary to override the city’s automated systems

Bellal
secondary

Heightened anxiety pressing against flickers of historical fatalism, desperate to avoid the city’s lethal defenses

Bellal moves cautiously around the control room, first observing the city’s brain before being drawn to the red-lit alcoves as the antibodies form. His urgency increases as he realizes the immediate danger, prompting him to call the Doctor’s attention to the unfolding threat.

Goals in this moment
  • • Alert the Doctor to the new threat within the city’s control room
  • • Fulfill his role as a guide and witness to the city’s dangerous evolution
Active beliefs
  • • The city’s defenses are too powerful to resist without external intervention
  • • Historical patterns of Exxilon subjugation to the city may repeat here

Doctor's Sabotage Circuit Boards

The Doctor assembles three salvaged circuit boards into a jury-rigged device, directly interfacing their exposed components with the city’s neural interface ports. Blue sparks crawl across the solder joints as he deliberately corrupts the defense system’s logic by introducing paradox equations, aiming to induce catastrophic failure.

After: Physically integrated into the city’s neural system. Soldering …
Before: Salvaged from an unknown location, kept in the Doctor’s possession. Circuit boards show exposed soldered joints, blinking diagnostic LEDs, and tangled wiring.
After: Physically integrated into the city’s neural system. Soldering joints damaged by sparks, LED lights flicker erratically as the device begins interfering with the city’s control systems.
