A couple hours passed without incident and the night air was calm, with a slight cold breeze coming from the west that felt really good on David's body. His comrades were sound asleep so there wasn't much to do except tend to the small fire and keep a look out for anything potentially dangerous.

Suddenly there was a noise in the forest much like a twig snapping, however David knew what it sounded like when you stepped on a twig and it was nothing special. He got up on his feet, for what that sounded like was a tree falling over. David then heard an eery wail, drawn out to sound...unnatural. 

Needless to stay, he went and shook Nathan, trying to wake him, for whatever was out there sounded too close.
