### 2.1.4: More about geography

Olympian provinces are arranged in a square grid. Travel is possible in the four main compass points. Thus, to move diagonally, two `move` orders are required. To move northwest, for instance, one would first need to ```move` n`', then ```move` w`'.

The map coordinates for a province may be read from the province's entity number. The row is represented by the leading two letters, the column by the two digits. The northwest corner is [aa00], with rows increasing to the south, and columns increasing to the east.

For example, a world 100 by 100 provinces would be numbered:

          00   01   02  ... 99
        +----------------------
      aa|
      ab|         ab02
      ac|    ac01 ac02     ac99
      ...
      ...
      dv|         dv02

Entity numbers for sublocations do not correspond to any coordinate system.

The map wraps at all edges. Traveling west from ac00 will lead to ac99, for instance.
