Vis: As the early summer new moon begins waxing, the ghosts’ might levels return to 3, and they leave cobwebby trails that contain vis.
Appearance: The ghosts are invisible to characters without an appropriate virtue. When seen, they are still indistinct, little less than human-shaped blobs. When their might increases, they appear more substantial, taking on the form of peasants and farmers of various ages, clothed and equipped as if from 100s of years ago.
