Device to Repel Xoanon's Creatures

A squat cylinder, roughly hand-sized, hums with a low thrum as the Doctor activates it outside the village perimeter. Its metallic surface glows faintly at one end, casting a pale light over the ground where the Doctor sets it down. Leela watches warily as its signal barrier flickers to life, intended to block Xoanon's external creations—but the creatures' voices still seep through, exposing the device's critical flaw.

Purpose

To create a sonic or electromagnetic barrier that would repel or block Xoanon's external signal-based entities from breaching the village's defenses.

Significance

This device's failure reveals a deeper vulnerability in Xoanon's control system, shifting the narrative focus from physical defenses to an internal technological flaw. It catalyzes the realization that Xoanon's influence permeates its own defenses.

Doctor and Leela uncover Xoanon’s voice flaw

The Doctor activates and positions the squat cylinder outside the village perimeter, humming steadily as it emits a low-frequency vibration and faint blue glow from vacuum tubes. The device functions as a signal barrier intended to block external creatures, but its activation and subsequent discussion reveal its critical flaw when Leela questions the immunity of all forms of energy to the barrier.

Before: Newly constructed and untested, resting inert on damp ground with copper coils and glowing tubes disassembled and jury-rigged.
After: Activated and humming, glowing faintly but emitting no discernible effect on external creatures; its signals are still vulnerable to internal infiltration by Xoanon’s voice.
