A couple of things you can do. Normally, Advanced Fog of war could automatically preserve places the characters have seen, but this won't work for you for two reasons: 1 Advanced Fog of War is automatic, and you want manual control. 2 Advanced Fog of War is currently broken, especially in combination with Dynamic Lighting Also normally, you could just use plain Fog of War to reveal sections of the map as they play, but you want to use the Dynamic Lighting tools to control vision and movement in the encounter areas. My suggestion for you is to use light crumbs . These are tokens which provide vision for all characters. You can drop these in areas previously explored. The method to make them is thus: Drop a token you want to use for a light crumb. It doesn't need to represent a character. Assign control of that token to "All Players" Give it appropriate vision and light to cover what would be seen in the area you want to reveal. I'd suggest light to 100 feet, dim starting at -5. This keeps the revealed area dim, but visible. Put it in an explored area. Copy and paste new ones as needed as they go along. All players will be able to see the dim vision provided by the light crumb. If you want to make sure no player grabs a light crumb and drags it around the map, you can use regular Fog of War to conceal unexplored areas. Here is an example from a recent game I ran. The players are in the Lower Right, where the bright light is. I have dropped light crumbs in each previously explored room. (They look like little eyeballs)
