Do you mean abstract sprites (like icons) or something similar to the town tiles I have now? (most can be overlapped over other terrains.)
This is exactly what I am asking about. Just more types of small locations, like cave entrances, dungeon entrances, question marks, etc. Different things that can be used for the journal pins in foundry since I use these hexes to indicate an 8 mile area. Each hex is a pretty sizable area with lots of stuff in it.
