Object
Marsh Gas Pocket (Tillingham Marshes)
A volatile accumulation of methane and other combustible gases lurking beneath the peat's deceptive stillness, marsh gas here surfaces as a thin, blue-tinged haze drifting between sedge and reed stems. The Doctor recognizes its presence by the sulfurous odor and the way Jo's boots sink deeper with each step, submerging her dangerously close to pockets of the deadly vapor. As the Drashigs advance, he exploits the gas's latent energy by channeling it upward with a flick of his sonic screwdriver, igniting it into a roaring fireball that sends tongues of flame licking along the marsh's uneven surface.
