Swarm

As the convoy desperately drove toward the distant entrance of an old tunnel, the Devouring Cloud finally reached the gorge. The sky disappeared, blotted out by a slithering mass of the winged abominations, and submerged the world into impenetrable darkness. Even the dim glint of the shimmering stars was extinguished.

The swarm flowed down the slopes of the mountains like a tidal wave.

Penetrating the armored frame of the Rhino, a deafening rustle of countless beating wings assaulted Sunny's ears. He grimaced, glanced at the screens one last time, and dashed back to the roof hatch. Once he climbed outside, the noise grew many times more violent, making it seem as though a hurricane was raging around him.
