During the previous year, the Pathfinders located a strange artifact in an Azlanti temple: the clockwork compass. This artifact is shaped as a normal compass, however it has four empty slots that look as though they'd fit a number of different aeon stones. Sorrina Westyr, the master of spells in the Pathfinder Society, calls on the PCs to help her with some experiments. But of course, as it's a Pathfinder experiment, nothing ever goes as it seems!
