We saw the already weak light vanish before us, tons of solid, cold rock collapsing behind us but we never gave up, well, until now. Our water and food soon finished and fatigue came in. Most of our friend's cold, vulnerable bodies were under that pile of rock. We have already passed our first night, I couldn't sleep, there were shadows in that dark cave, they moved, writhing, twitching... There was also that scratching, never-ending, high pitched... Dismembered bodies, severed limbs, and dry corpses, full of flies. Flies! If there were flies there could be an exit to the surface!
