Fog of War

The fog of war (or fog-of-war) is a black shading meant to represent the player's knowledge of a map's terrain. It obscures unexplored regions of the area map and must be cleared to interact with the region. Coordinates for these areas cannot be manually selected until the fog has been cleared. Previously visited areas are visible on the map and are denoted with a tinted overlay: coordinates may be selected and party members may retreat back to these explored areas.

Fog of war is distinct from line of sight: even if a player has the entire area map visible, they are not able to execute actions beyond the line of sight. The spell Clairvoyance will flag the entire map as "explored", clearing the fog but leaving the tinted overlay.
