Here in Sullen

Will Coy Bedlam survive his stay in Sullen?
Painfully he raised his head, looking out into a dreary drizzling environment, seeing his headlights purposefully reflecting off a roadside sign, with a name of a town called Sullen. Today’s population is 169.
“What does that mean?” He growled, “Today’s population is 169.”
Then he asked, “Where the hell is Sullen?” forcing himself to move, he dragged a map from his glove box, “I’ve never heard of it before…” And strangely it didn’t appear on the map either.
