This room is mysteriously dark.  It is narrow and long, with sparse
furnishings.  There is a small bed in the corner, with clean white sheets. 
The walls here are made of wood, obviously placed over the stone behind it. 
The walls have been painted green and blue, creating a soothing atmosphere
from the rest of the castle.  The room continues to the east.
