Cult of Gyronna
The sixth time the PCs return to town (or even later, possibly), another menace invades town. Rumors fly that a secret mystery cult dedicated to the hag-goddess Gyronna has taken root in the town.
As goddess of hatred, extortion, and spite, Gyronna’s cult represents a threat to any community, and tales abound of isolated communities throughout the River Kingdoms that tore themselves apart from within due to the machinations of the Angry Hag’s priestesses. If the cult has indeed infiltrated the town, it must be found and eliminated before it can set the townspeople at one another’s throats.
