Dark Tower Parapet

A precarious stone ledge runs along the summit of the Dark Tower’s exterior, its uneven surface slick with morning dew. The parapet’s coping stones jut jaggedly against the wind, offering no true shelter—only a narrow foothold for the Third Doctor and Sarah as they navigate the exposed summit. Sarah’s trembling fingers dig into the cold masonry, her pulse quickening with each gust that ripples across the crumbling stonework. Beneath her feet, the drop yawns into the mist below, amplifying the tower’s brutal height. The parapet’s broken merlons reveal centuries of erosion, but today, its only purpose is to stand between them and a fatal misstep.
