Ranger outpost

"Man, I wish we brought more coffee, we ran out already!"

"Don't you mean, you drank it all?"

"It's Sharp's fault for forcing us to stay here way longer than we were supposed to."

Two unhappy rangers conversed by the fire beneath the east watchtower. It was the last ranger outpost and it marked the end of the territory 'controlled' by humans, meaning that beyond that post it was no man's land. That explained why they ran out of coffee and also why they were in such bitter mood, because they've been cut from civilization far longer than they should have and it was all due to the person that just walked in on them while they complained.
