With the fall of Runelord Belimarius, ruler of the New Thassilonian city of Xin-Edasseril, relics from ancient Thassilon have found their way onto the black markets throughout the Saga Lands. Much of this trade is centered in Riddleport. The Pathfinder Society is doing what it can to obtain these relics to catalogue and preserve them, and has amassed quite the stockpile in a warehouse within the city. This makes for an irresistible target for some pirates. It'll be up to the PCs to see that these treasures are kept safe.
