Predator ship invisible

As the alien disappeared into the darkness, the lasers silently retracted and the ramp withdrew, becoming flush with the spacecraft’s glimmering surface, not a hint of a seam joint. The craft became an impenetrable shell, pure and pregnant as an egg. Then its glossy copper-colored exterior began to fade and cloud. It too was becoming one with the night, just as its captain had moments before. Soon it held its place invisible as a god.
