The PCs are tasked with escorting a valuable item slated to be gifted to a powerful potential ally of the Pathfinder Society, but as they are being briefed on their mission, an unknown thief is pulling off a heist within Heidmarch manor, and the item the PCs were to escort has been stolen just as Venture-Captain Shiela Heidmarch goes to show them the item. The PCs must pick up the thief's trail in a race across Magnimar to recover the treasure they haven't even had the opportunity to see, much less guard.
