Doctor abandons delay and orders Tegan to act

The Doctor and Tegan discuss the Tractators' gravity motor and the urgency of stopping their plan to control Frontios. When the Orderly is dragged away by a gravity beam, the Doctor realizes hesitation is fatal—they can no longer rely on sabotaging the machine. He abruptly abandons delay tactics and orders Tegan to follow him into direct confrontation, recognizing that the Tractators' acceleration demands immediate, risky intervention to prevent galactic infestation.

Who Was There

Characters present in this moment

5

Sharply focused and resolute, with latent tension barely concealed beneath his clinical exterior

The Doctor transitions from analytical exposition to decisive urgency when the Orderly is snatched by the gravity beam. He abandons caution and orders Tegan to abandon stealth and follow him into confrontation with the Tractators. His shift reveals a core belief: passive resistance is fatal when facing the Tractators’ accelerating plan.

Goals in this moment
  • To stop the Tractators’ gravity motor from completing before it allows planetary theft
  • To avoid further assimilation by recognizing that delay has become a death sentence
Active beliefs
  • Physical presence and intervention are now the only viable path
  • The Tractators’ expansion cannot be halted by sabotage alone
Character traits
tactical adaptability urgent decisiveness cosmic detachment protective authority

Alert and alarmed, her fear subsumed into resolve to act

Tegan reacts to the Doctor’s order with instinctive readiness, abandoning the cave’s fragile safety. Her position shifts from observer to active ally, abandoning prior skepticism about rash action. She follows without hesitation, revealing her loyalty overrides caution as the gravity beam’s menace crystallizes the threat’s immediacy.

Goals in this moment
  • To prevent further loss of life under the gravity beam
  • To support the Doctor’s risky intervention despite residual misgivings
Active beliefs
  • That the Doctor’s judgment is correct when crisis accelerates
  • That inaction would doom more people to the Tractators’ assimilation
Character traits
instinctive loyalty moral urgency courage under pressure

Gravis
secondary

Emotionally detached, embodying alien logic that frames terror as utility

Though physically absent from the cave, the Gravis’ influence permeates the moment through the gravity beam’s sudden violence. His unseen presence drives the crisis: the beam is the Tractators’ instrument, designed to assimilate organic minds to power their conquest. His logic—planetary domination as cooperative harmony—becomes exposed as predatory expansion as the beam seizes its victim.

Goals in this moment
  • To complete the gravity motor’s ring and enable planetary theft
  • To assimilate fresh organic minds to reinforce Tractator machinery and power
Active beliefs
  • Organic minds are replaceable components in a mechanical system
  • Coercion disguised as cooperation accelerates conquest
Character traits
ruthless pragmatism mechanical control via assimilation cold utilitarianism
Follow Gravis's journey

Terrified, overwhelmed by an irresistible force beyond human control

The Orderly, setting down his lamp, becomes the first visible victim of the gravity beam’s pull. Dragged upward in a sickly pink-purple glow, he becomes a symbol of immediate peril and confirms the Tractators’ relentless predation. His fate crystallizes the Doctor’s realization that delay equals death for anyone left in the beam’s path.

Goals in this moment
  • To survive the beam’s pull and return to safety
  • To warn others of the gravity beam’s danger
Active beliefs
  • Obedience to colonial orders is futile against the Tractators’ power
  • The cave does not offer immunity—violence can find anyone
Character traits
helplessness panicked surrender victimhood under alien technology

Location Details

Places and their significance in this event

2
Emergency Shelter Fissure

Though intended as a refuge, the Gravitic Refuge Cave becomes a hollow sanctuary when the Orderly’s scream pierces the cave’s relative safety. The trapped juxtaposition of shelter and sudden peril forces the Doctor and Tegan to abandon caution. The cave’s jagged walls and damp air amplify the gravity beam’s alien howl, turning sanctuary into a death trap the moment the beam arrives.

Atmosphere False safety unraveling into terror
Function Failed sanctuary exposing vulnerability
Symbolism Represents the futility of isolation against cosmic predation
Access Limited to those already inside; no new ingress prevented
Damp rock with pockets of cool air Sounds of machinery and screams bleeding through from the tunnels
Tractator Tunnels (Gravity Engine Conduit)

The Tractator Tunnels function as the gravity beam’s conduit, transmitting the Tractators’ mechanical force into the cave itself. Their deceptive layout, slick surfaces, and engineered gravity shifts make them ideal weapons—now turned inward to snatch victims from sanctuary. The tunnels’ role as arteries of planetary control becomes literal as the beam reaches across space to claim its prey.

Atmosphere Engineered menace bleeding through stone
Function Active weapon system and transportation conduit
Symbolism Embodies the Tractators’ co-opting of natural space for domination
Access Controlled by Tractator machinery; inaccessible to casual resistance
Slick walls reflecting emergency lighting in fragmented glints Subtle distortions of gravity inducing stumbling footsteps

Tractators

The Tractators manifest through the gravity beam’s violent extraction of the Orderly, proving their planetary-scale technology has activated locally. Their hidden organizational goal—control through assimilation—becomes visible as the beam claims its first victim in the cave. Their influence is transmitted through mechanical systems, bypassing organic defenses with cold efficiency.

Representation Through the gravity beam’s alien technology and the Orderly’s forced assimilation
