dense cloud

From below, it looked like the dense clouds were on fire.

They moved out on the plain, a dense cloud of men.

It came down from the mountains like a dense black cloud.

Darkness was suddenly all around, as though a dense cloud had passed before the sun.

Or it would have been, had dense clouds not rolled in.

The dense clouds of smoke were now no more than a hundred yards away.

In the dense cloud of dust, they could see almost nothing beyond the rocks.

He saw a small, dense cloud of Darkness hanging above the ground.

But from behind the dense clouds of smoke here, a new environment is beginning to emerge.

Now the smoke was a dense cloud through the forward ports.
