Now a heavy racket echoed through the chambers under the domed city.

Doors closed somewhere below, echoing in the depths under the stairs.

A faint thought echoed in my mind, under the sound of my gasping breath.

She paused, listening to her words, or to other words echoing under the moonlight.

He too had heard this ill-boding whistle, and the report which echoed under the tilt.

Thunder - the natural kind - rolled across the sky, then echoed back under clouds that had become almost black.

It leapt out echoing too sharply under the arched ceiling.

A moment later her whisper echoed through the half-flooded tunnel under the wall.

For a moment, the sound echoed back to her, vacant and forlorn under the wide sky.
