Shunned Valley of the Three Tombs (Pathfinder 2E)

Far from the nearest town, hidden deep in the forest, lies a marshy, boggy valley. Woodsmen and hunters shun the place—kept away by rumours of a terrible beast lairing within and of a ghost haunting the valley’s boggy mere. But, as well as great danger, treasures magical and mundane may yet lie unclaimed in the valley for three unexplored tombs built by ancient hands, stand amid the mud and reeds. Dare you explore the Shunned Valley of the Three Tombs?

This edition also contains extensive details of the town of Dulwich--a perfect base from which the PCs can launch their exploration
