Spiral Stone Staircase

A narrow, circular staircase spirals upward through the dim warehouse, its worn stone steps catching the flickering emergency lighting. The air carries the scent of damp concrete and scorched metal from the Cybermen's recent combat maneuvers. The tight confines amplify each footfall—the Doctor and Ace's boots clattering against the uneven risers as they sprint upward during the chase, their shadows stretching long across the curved walls. The staircase's ancient stone contrasts with the warehouse's modern industrial chaos, its age worn smooth by countless unseen hands over decades. As Cybermen pursue below, the stone walls vibrate with the pounding of mechanized feet, the rhythm of pursuit becoming the heartbeat of survival.
