· Frontios Part 3

Doctor discovers advanced Tractator intelligence

The Doctor and Tegan pause in the claustrophobic tunnels beneath Frontios. As Tegan voices frustration over their endless dead ends, the Doctor examines strange chippings on the cave floor. What appears to be mere debris to Tegan reveals itself under the Doctor's scrutiny to be freshly machined rock—clear evidence of deliberate excavation. His observation escalates quickly from wonder to certainty: these machines are not the crude tools of instinctive creatures. The Tractators possess sophisticated abstract reasoning and engineering capacity, contradicting every assumption about the colonisers' faceless oppressors. This revelation cuts to the heart of the deception Frontios has endured. Brazen's dismissal of the threat is rendered absurd, the silent conspiracy beneath the surface more sinister than anyone imagined.

The Fifth Doctor
Time Lord
 primary

Focused fascination masking urgency to share discovery

The Doctor pauses mid-stride, crouching to pluck angular rock shards from the tunnel floor with deliberate care, his keen eyes discerning unnatural precision in their cut edges. His voice rises from the inspection, drawing Tegan’s exasperated reply.

Tractators

These sharp-edged shards, once part of the cave wall, are lifted by the Doctor to reveal unnaturally clean cuts produced by advanced cutting tools rather than natural erosion. Their hardness and striations contradict expectations of primitive excavators, turning mundane geology into decisive evidence.

Places and their significance in this event

1
Frontios Tunnels

The Dark, confined corridors pulse with erratic green and purple light off uneven walls sloping at unsettling angles. Tight passages demand stooping progress, amplifying each footfall and breath, while distant clatters and distant gravity surges heighten tension. Here, within the unstable rock, the Doctor stops and kneels, making space into a temporary laboratory of deduction.

Atmosphere Cramped and tense, choked with creeping dread and flickering light
Function Limited laboratory for empirical discovery under duress
Symbolism Embodiment of hidden intelligence and deceptive simplicity beneath the surface
Access Dictated by narrow squeezes and unstable roof strata
Unevenly lit walls pulsing with irregular coloured glows Sloping floors forcing awkward stances and slow movement

Organizations Involved

Institutional presence and influence

1
Tractators

The Tractators’ influence is indirectly exposed through the mechanical precision of the rock chippings rather than any direct presence. Their unseen excavators labored here recently, crafting tunnels with advanced tooling that belies earlier assumptions of instinctive brutality. Their systematic alteration of the cavern underlines their sophisticated organizational capacity.

Representation Revealed indirectly through forensic evidence of their machined activity
Power Dynamics Operating covertly beneath the colonists’ assumptions and our protagonists’ awareness, increasing their perceived menace
Impact Challenges institutional narratives that underestimate the Tractators’ capabilities and threat level
Expand subterranean infrastructure to harvest human resources Maintain secrecy regarding the extent of their intelligence and engineering Controlled excavation and mechanical augmentation of the environment Psychic assimilation of human minds to fuel technological operations
