“On the first day, Mariana walked into the field; she came back sightless. The second day, Grigor did the same, and he ran back with a broken arm. The third day, it was Valka, and she came back fine… but all she does now is stare into the fire.”
The preglavica appears as a headless woman in white, appearing at midday. Based upon her reaction roll, she may react in one of three different ways. A friendly reaction means that the party will become lost; a neutral reaction will cause her to blind them (save vs. wands) for 24 hours; a hostile reaction will mean an attack. Any damage roll of 9-10 results in a broken arm (6 weeks or magical healing to restore). A preglavica is immune to all non-magical weapons, and can cast cause disease at will.
On a reaction roll of 12, a preglavica may foretell a person’s death, based upon an overwhelming telepathic image. The GM should not share the nature of this with the player, but it will play out as follows: On three occasions, the character may turn a failed saving throw into a success, or change a damage roll on themselves into the minimum. The GM may do the opposite once.
