Cloister of the Frog God

A dark cloister stands on a desolate ridge above vast swamps, dedicated to the terrible frog god Tsathoggus. Destroyed and rebuilt throughout history, the monastery is again occupied by cultists whose spies move through nearby settlements and whose offerings support their rituals. Beneath the old walls, ancient evils stir in hidden grottoes and underground sanctuaries.
