I found a solution! I was looking for the definitions of ‘above’ and ‘below’ in the standard rules extension. For example: above is defined as The verb to be above means the reversed mapping up relation.
With the help of the ‘above’ example in Section 3.3, the solution is simple:
Chapter 1 Definitions
The verb to be westward from means the reversed mapping west relation.
Chapter 2 Rooms
Foo and bar are rooms. Foo is a room westward from bar.
The map connections are correct and the extraneous nowhere is nowhere (pun intended) to be found.
