From publisher blurb:
A Pathfinder Society Scenario designed for levels 1-5.
Tragedy has struck, and the Society’s attention must turn from academics to action as they infiltrate a seemingly impenetrable facility in the heart of Ostenso, one of Cheliax’s greatest ports. They must act quickly, for only the distraction of a national holiday can provide the PCs the cover they need to get in, get the job done, and get out without drawing the attention of an entire city’s guards.
“The Infernal Inheritance” is the final scenario in the three-part Faithless and Forgotten campaign arc. It is preceded by Pathfinder Society Scenario #7–14: “Let Bygones Be” and Pathfinder Society Scenarios #7–16: “Lost Colony of Taldor.” All three chapters are intended to be played in order.
Content in “The Infernal Inheritance” also contributes directly to the ongoing storylines of the Dark Archive and Liberty's Edge factions.
