The term seeks to capture the uncertainty regarding one's own capability, adversary capability, and adversary intent during an engagement, operation, or campaign.

The Advanced Fog of War feature clears fog away dynamically as a token moves across the Page. Each token's path is individually recorded, so each Player's view of the Tabletop will vary from person to person depending on which tokens they have control over.

As Vince has stated, you can adjust the GM Opacity with the slider, try the CTRL+L, or you can rejoin as a player to see what the players see. The fog appears as a solid black area to players, but for the GM it's a semi-transparent layer.
