The Coven's Curse

From publisher blurb: A trio of witches have made a terrible pact with a small village, requiring the townsfolk to elect a sacrifice to the foul hags every full moon. Agreeing to help the town in their predicament, the players will then have to find the three hags before the next full moon, either slaying the witches in combat or bargaining with the trio of chaotic sorceresses for another adventure entirely… This adventure can be implemented as a standalone quest framework at any point in the party’s adventures — at any town, village, or settlement suitable. Tracking down the witches may take several sessions, and can be written into your campaign as a side objective whenever and wherever the player’s travels may take them.
