Section 5 - Panopticon
The description of the Circular Chamber is "The hum of machinery is ever present here, rumbling down into the sub-sonics. Pale white walls encircle a series of engraved circles on the floor, and at the center - like the pupil of some great eye - sits a round console which reaches all the way up to the ceiling.[paragraph break]The room's single exit lies to the [if the activated of the keyhole is false]east.[otherwise]north."
Before going north in the Circular Chamber:
if the activated of the keyhole is false, say "No exit lies in that direction." instead.
Before going east in the Circular Chamber:
if the activated of the keyhole is true, say "No exit lies in that direction." instead.
The walls of the chamber are scenery in the Circular Chamber. Understand "pale" or "white" or "walls" or "circles" as the walls of the chamber. The description of the walls of the chamber is "The walls and floor are pale, white and seamless except for the engraved circles. There are six of them - set at various distances from the central console." Instead of doing something other than examining or pointing at to the walls of the chamber, say "Nothing useful can be achieved by fiddling with the engraved circles."
