A sound brushed the edge of the platform—a carrier drone, larger than the rest, its belly lit like a chapel. It cleared the Aeroplex and dipped into the glow of the city center, leaving behind a scent like burnt sugar and something else: a faint metallic tang that made Mira’s teeth ache. With the drone’s passing, the platform coolly resumed its previous cadence, and for a bitter second, she wished that silence could be permanent.
