During the game, the Mat, Grid, and Tiles (in this file) sort the waiting chits easily and tell you at a glance which maps have been revealed and where they are.
Make sure you print centered and not scaled.

(But it would have added an extra base colour to the printing and significantly increased publication cost.) C and D secret paths are thus supposed to be outside the Mage's special path finding power, and these are the two paths relevant to the Dwarf and to the Cart. As such, I recoloured them Orange in the micro pictures on the Mat in this file.
