Divine and planar battle maps
These are the maps for encounters that are not happening in an ordinary place. Consecrated ground, a shrine at the end of a pilgrimage, a hall that does not obey normal architecture, or somewhere the boundary between planes has failed and taken the geometry with it.
Running one at the table
A planar map is allowed to break the rules the rest of the set follows, and that is its job. Floating ground, impossible symmetry, light coming from the wrong direction. Used sparingly it tells the table that the ordinary constraints do not apply here, before you have explained anything.
How big to make it
Temples and halls read at 30 to 40 squares. Planar spaces can go wider, because the sense of somewhere unbounded is most of the effect.
What you can make
Pick one and RPGenie writes the map from it. This is not a library of 15 finished pictures: they are starting points, and the map you get is generated for your table.

Every art style
The same map, drawn twelve ways. Style is picked per map, so a campaign can stay in one look or change with the scene.
