Percy:   Room 5 prepares us for the transition into three-dimensional Abstract Space.   A big warning.  Abstract linearity has two main components: writing and time.  It's easy to forget the power of the latter, and very difficult to break it.  Because we are conditioned to think of the past as behind us and the future ahead.    

Red:  Well, that's understandable.

Percy:  I know.  Just keep this in mind, because to break the cognitive distortion of linear time we will jump to various points in the 4D fabric of Abstract Space.  And the primary tool for this plotting is the Navigational Quadrant...let's head on in and meet it.

Red:  Huh...this opening appears larger...

Percy:  The Navigational Quadrant is based on the old maritime instrument that triangulates bearings off celestial bodies.  I've updated it for Abstract Space, where the bodies we triangulate off are Concepts/Object pairs.  Take a look up on the Big Screen.  See anything familiar?

Red:   So...I see the Propaganda Portal up top.  And I suppose the anchor represents the paired Object -- the territory of the trade infrastructure.
