Object

Tractator Beam

A disorienting pink-purple light weapon that erupts from the Tractators' gravity manipulation field, manifesting as eerie violet tendrils with irresistible gravitational pull. It can ensnare both living targets and loose objects (like the brass lamp), as demonstrated when an Orderly's lamp was violently seized alongside him. The beam's sickly pink-purple hue cuts through dim environments with unnatural visibility.

S21E9 · Frontios Part 3

Doctor pulled by gravity beam

The gravity beam manifests as a disorienting pink-purple light that suddenly engulfs the Doctor, yanking him off balance and pulling him backward with intense force. It serves as a direct and violent extension of the Tractators’ power, rendering escape nearly impossible through brute mechanical advantage and artificial gravity manipulation.

Before: Latent as a threat, recently activated as the Doctor rounds a corridor into a green-glowing tunnel intersection

After: Fully engaged, actively dragging the Doctor backward through the tunnel with sustained intensity

S21E9 · Frontios Part 3

Doctor triggers gravity beam escape

The gravity beam remains a tangible menace, its pink-purple glow intensifying as it locks onto the Doctor. Upon impact with the phosphor lamp, the beam suddenly collapses, its crushing force dissipating violently. This sudden release frees both companions and signals the Tractators' system failure, albeit temporary.

Before: Active, oppressive, and focused, dragging the Doctor violently upward.

After: Disrupted and extinguished, its machinery compromised by the sudden energy surge.

S21E9 · Frontios Part 3

Doctor discovers Tractators rescue purpose

The gravity beam’s pink-purple light erupts suddenly, filling the tunnel with an eerie glow that shifts in intensity as it locks onto the Doctor. The beam’s sickly luminescence pulses irregularly, casting distorted shadows and disorienting their footing, while its invisible pull drags upwards with violent force.

Before: The beam is dormant, undetected in the tunnel’s dim light, its lurking threat confined to geometric distortions in the air.

After: The beam’s light intensifies violently, its pull yanking the Doctor off balance and forcing Tegan to take cover against the cavern wall.

Doctor outmaneuvers Gravis as Tegan vanishes

The pink-purple Tractator beam suddenly erupts, locking onto Tegan and violently lifting her into the Operations Centre’s oppressive air. It functions as the primary tool of capture and intimidation, its unnatural light contrasting with the Doctor’s calculated indifference as he redirects attention away from it.

Before: Dormant and unseen, integrated into the Operations Centre’s machinery, awaiting activation as a suppression tool

After: Active and illuminated, Tegan suspended within its sickly light, marking it as the central threat in this moment of escalation

S21E10 · Frontios Part 4

Doctor reveals Tractator gravity engine purpose

The brass oil lamp is set down by the Orderly as a normal act of routine. It serves as an immediate warning of abnormal forces when it is violently snatched upward without contact, pulled by the unseen gravity beam. This moment draws attention to the beam’s abduction mechanism, revealing the Tractators’ hidden influence over gravity.

Before: Placed on the cave-adjacent surface, lit and stable

After: Ripped from the Orderly’s grasp and carried upward by gravitational force, extinguished or lost from view
