Stone Circle of the Cailleach

The Stone Circle of the Cailleach is a prehistoric megalithic structure, its towering stones arranged in a precise geometric pattern near TARDIS landing coordinates. Romana’s instruments detect interspatial anomalies emanating from their ancient surfaces, confirming the structure’s unnatural properties beyond ordinary Druidic lore. The circle pulses with rhythmic red light during Vivien Fay’s visit, matching the pulsating glow Romana later witnesses in proximity, though her direct observations of the lit stones go unremarked by the casual Vivien.

Romana detects the stone circle threat

The Stone Circle of the Cailleach dominates the scene as an unnatural focal point, its sarsen stones pulsing with rhythmic red light visible to Romana but not remarked upon by Vivien. Its charged energy alters the atmosphere, compelling attention and reaction. Romana’s detection of its interspatial anomalies is subtly echoed by the circle’s sudden visibility, while Vivien treats its glow with detached interest, creating a contrast between supernatural significance and mundane observation.

Before: Inactive and overlooked, its red glow unseen or ignored by casual observers.

After: A pulsating red light emanates from the circle, now impossible to ignore and central to the characters' immediate experience.
