From the introduction: The Chapel of the Fountain is a Holy Lands adventure for 3-4 1st-level player characters. It may take place in any remote area that is isolated from a large Church or Monastery. The party should include at least one a Cleric or Saint and a Warrior (or other fighter type class). The PCs (obviously) should be good-hearted, as the primary motivation for the adventure is to save the life of a dying villager and rescue others.
