From the Back of the Book:
Something stirs in the land of Vesh - something unwholesome. In recent times, a relic of Mormo's destruction was brought to the care of the Vigils, but not without great sacrifice. The servants of the Hag Queen will stop at nothing to get it back - and the only thing that stands between them and the Serpent Amphora is your characters! Are they up to the challenege?
Usable alone or s part of the ongoing Serpent Amphora Cycle - which begins with "The Serpent Amphora." Serpent in the Fold is an adventure for characters of 3rd-4th level.
