From the publishers blurb:
A peaceful village of fisher folk and artisans. A friendly community safely perched high above the raging sea. On the surface life is grand, but who knows what trouble lies below?

This semi-sandbox setting is designed to give Dungeon Masters a broad level of freedom. The NPC rich coastal village, marketplace, and underground exploration area can serve as a one-shot starter scenario, or an area of interest between points within a larger crusade. To kick off local exploration, there are several adventure hooks offered—just pick a problem…or create your own.
