The Abbey of St. Martin

From publisher blurb: The Abbey of Saint Martin Rivkin has stood abandoned for nearly 50 years. The locals give the abbey a wide berth, both for the threatening aura of the place, and the occasional screams that some claim to emanate from within. But there are also rumors of relics or remnant divine wisdom to be found there.... This is an experiment in preparing an adventure scaled for three adventurer levels: A solo adventurer of 2nd to 3rd level; a small party of 1st level characters; and a small party of 2nd to 3rd level adventurers.
