Looking at the map, I noticed something odd. On the sides of the map are alternating dark and light sections, with each pair seeming to represent one degree (or whatever unit the Rosharans use). But if this is the case, then there are only 9.5 degrees between latitudes 30 and 40, and 7.5 between 0 and each of 10 N and 10S. Is this an error, or is there some reason for it, I wonder? (I'll admit, I'm having trouble coming up with a good explanation.)
