Concentric rings light
Concentric rings of light spread slowly through the granite, a choreography unfolding over eons. Faint impressions—like fossilized ferns in limestone—appeared at certain angles, dissolving with the slightest shift in view. A gentle electrical hum vibrated up from the floor, keeping rhythm with unpredictable pulses of illumination; the stone itself seemed to *respond*. As pressure differentials grew, they became audible, a distant choir echoing within its depths, and then quieted.
