In the top room of a tall watch tower(d)

You stand in the uppermost room of a stone watch tower. The room is plain and very small. There is a window in the southern section of the wall that looks out on the open ground around Dale--ground now covered by the beseiging army of orcs and easterlings. A large rug covers the stone floor below the window. Behind you, the floor opens onto the stairs that lead down. The roof of the tower is low above your head, conical in shape and made of rough wood. A plain chair sits against the wall.
The only obvious exit is down.
