In a large sleeping room(n)

As you walk into this large room, the first thing to strike you is the absence of guests. Where sleeping places normally would be, only dust remains. The only object in this threadbare room is a solitary mattress. Even you, the hardy adventurer, would have a hard time sleeping with the thought of a large army not far away... Sleep well!
The only obvious exit is north.
