You lie on the ground.
There is a big hole in the scorch earth. There are flames and smoke all around you. There is some trees and shrubbery, but most of the land around you is barren. The hole itself is about 20 meters deep, and at the bottom there is a big bulk. It might be stone, but it could be metal.
There is another sound, coming from underneath you. Something is moving down there.
There are more of you laying around on the ground. The sky is dark. So, it must be night.
