He sat up, slowly, but encountered no obstacle, there was empty space between himself and the cave's rock ceiling.

Tiff and the others stared at the solid rock ceiling.

The monstrous main computer towered toward the bare rock ceiling.

There were no windows, and a soft light issued from two tubes in the rock ceiling.

Before this dark opening, set into the rock ceiling above, was something that glowed.

She flashed the light around so that the beam illuminated the black rock ceilings and walls.

This level was like the one below except for the rock ceiling.

He looked at the rock ceiling of his cell.

He smiled and pointed upward toward the rough rock ceiling, then raised his hand further still.

Blinking away the tears to stare up at a gray rock ceiling above.
