A Pathfinder Society Scenario for characters of 3rd to 7th level (Tier 3–7).
All-out war has erupted on the long-contested border between the crusader nation of Mendev and the demon-infested Worldwound. With the magical defenses that once held the demons at bay failing, defense of the region now falls to small patrols of mobile soldiers to resupply, reinforce, and communicate between the border's many fortresses and outposts. With so much at stake, the Pathfinder Society has enlisted many of its agents to assist in the war effort, both to protect its own interests and to prevent the onrushing tide of demonic attackers from plunging the entire Inner Sea region into chaos. On one such wardstone patrol, however, the party may find itself facing an enemy of an entirely different nature.
