Sonic Time Scan Device

The concealed sonic emitter flares to brutal effect when Borusa turns the dial, emitting a focused pulse that disrupts Sontaran physiology. Masked by the Doctor’s distant taunting, the device delivers a surgical strike that collapses Sontaran discipline within seconds.

Chancellory Desk Small Drawer

The small drawer conceals the sonic emitter’s control panel, accessible only to Borusa. Its unobtrusive brushed chrome handle is silently disengaged moments before the critical dial is turned, enabling covert activation.

Before: Closed and unremarkable beneath the Chancellory desk’s leather surface, seemingly innocuous
After: Opened, with the sonic device’s control circuit now exposed
Sonic Activation Circuit

The small circuit device embedded in the control panel dictates the sonic pulse’s timing and strength. Borusa’s manipulation of the dial sets a precise limit—enough to disable Sontarans but too brief to alert nearby APC systems.

ancient stone floor hidden paneling behind which mechanisms groan open gold-threaded tapestries of Rassilon’s sigil
Panopticon Chamber

The Panopticon chamber becomes the staging ground for Sontaran collapse. Its resonant stone walls magnify the sonic pulse’s impact, leaving the occupiers disoriented and unable to coordinate responses while human onlookers flee upward in panic.
