Stranded on Yesterday's Tide

A Pathfinder Society Scenario designed for 1st- through 4th-level characters.

The Pathfinder Society has heard reports of a ship sighted over and over, apparently following the same path before vanishing each week. This unfortunate ship is stuck in time, repeating the same week over and over. The crew has tried everything to escape this fate, and gave up years of the same week ago. The PCs must find a way to return things to normal and save the crew from an eternity of this single week.
