The entire length of this hall is unadorned
and very [clean]. The brass-like Metal here has
been carefully polished, making it very reflective.
The entire corridor is very brightly lit, and
the images of those in the hall are reflected in
the walls except at the 20-foot-wide section
around the secret door (19A). This section of the
wall is covered by a permanent illusion that
hides the door to room #22. It will NOT disappear
if touched. To open THE DOORS, characters must
reach in and find the handles by touch (unless
magick such as true seeing is used). The other
doors are normal secret doors.
