Cairn of Stone Hearts

Xen'drik Expeditions Scenario An Adventure for 6th Level Characters From the introduction: "Hearts of stone can break like any other, some may even crumble with the slightest touch. Beyond the pillars of the sun and along the great waste, twenty thousand stones mark the harvester's tomb. In the sacred place fire points the way to what, once broken, can never mend. The crumbling thing, thrown into the hydra's mouth, can stop the great shadow for a measure of three score and seventy."
