When a Prisoner draws a Light Eater, it activates immediately. The Light Eater’s attack causes one Prisoner who isn’t adjacent to any other Prisoners to go lights out. These Prisoners are referred to as “isolated.” The active player decides who will be affected.

The Light Eater's target can be any isolated Prisoner, including the Prisoner who drew it. After resolving this effect, the active player flips the Light Eater tile and places it as a Pit (if they are still lit).

D. Green & Yellow are connected and safe.

E. Purple is isolated and vulnerable.

F. Red & Blue are isolated and vulnerable b/c of the wall between them.
