From publisher blurb:
A Pathfinder Society Scenario designed for levels 5–9.
Two years ago, the Pathfinder Society concluded its extended campaign to find, reclaim, and explore the lost sky citadel Jormurdun. After ousting the vile demons and duergar within, the Society turned over control to their dwarven allies, who have defended the ancient fortress ever since. A recent raid by duergar slavers has captured some of Jormurdun’s dwarves, who have disappeared into the Darklands and bound for the cruel capitol of Hagegraf. Only the Pathfinder Society is equipped and able to launch a daring rescue into the lightless depths, intercept the slaver convoy, and save these dwarves from a grisly fate.
Content in “Captives of Toil” also contributes directly to the ongoing storyline of the Liberty’s Edge faction.
