Submerged Cavern System

Marshy Cave System

The cave presses inward like a damp lung, its walls slick with condensation that mirrors the emergency glow from the TARDIS’s console lighting. Shallow black pools of standing water reflect the distorted shapes of jagged rock formations that jut upward like broken teeth. The air tastes of wet stone and something older—a sharp mineral tang that coats the throat and lingers in the lungs. Ahead, the cavern narrows to a tunnel where Adric once hunted K9’s severed head, returning empty-handed but for the echoes of his own footsteps. Beyond that constriction, the space broadens again into a wet cavern where Romana lies stricken, her breath shallow against the poisoned air. The cave’s cold breath seeps through clothing, bringing with it the scent of unseen marsh growth and the faint, skittering presence of its native creatures moving just out of sight in the dark.
