In the foreboding north, the demonic hordes of the magic-twisted hellscape known as the Worldwound encroach upon the southern kingdoms of Golarion. Their latest escalation embroils a preternaturally handsome and coolly charismatic swindler named Gad, who decides to assemble a team of thieves, cutthroats, and con-men to take the fight into the demon lands and strike directly at the fiendish leader responsible for the latest raids—the demon Yath, the Shimmering Putrescence. Can Gad hold his team together long enough to pull off the ultimate con, or will trouble from within his own organization lead to an untimely end for them all?
