From the publisher's website:
Several years ago, a Taldan Zyphus cult took over a famous Oppara opera house, murdered a Pathfinder, and turned dozens of Taldor's wealthiest citizens into the walking dead. The Pathfinder Society has finally tracked down their hideout and sends you to Oppara for one purpose: revenge. Can you face the servants of Golarion's god of accidents unharmed or will you find yourself among Zyphus's cursed souls?
Among the Dead is a follow-up scenario to Pathfinder Society Scenario #7: Among the Living. When played together, the scenarios create a mini story arc in Taldor's gilded capital, Oppara.
A Pathfinder Society Scenario designed for 1st to 7th level characters (Tiers: 1-2, 3-4, and 6-7).
This scenario is designed for play in Pathfinder Society Organized Play, but can easily be adapted for use with any world. This scenario is compliant with the Open Game License (OGL) and is suitable for use with the Pathfinder Roleplaying Game.
