Bridge Corridor Toxic Gas

A thick, acrid plume of toxic gas that rolls over the beach under the Valeyard's control. Its mist carries a sharp chemical stench, burning eyes and throat while causing involuntary gagging and respiratory distress. The gas thickens to incapacitating levels, forcing retreat and triggering survival instincts as it clots in the lungs with each breath. Initially used as a psychological weapon to escalate from illusion to lethal force, the gas represents the Valeyard's shift to direct violent aggression against the Doctor and Glitz.
