Black Ship of the Sunless

From the publishers blurb:

As a larger body of work, Black Ship of the Sunless has a central theme – corrupted history. This first episode, Black Waters, serves as the inciting incident, transitioning your players from reality to the surrealistic version of the island of Cozumel on the Yucatán peninsula in the year 1519. The player’s ship is about to smash into a coral reef and find themselves marooned and trapped at the footsteps of a pre-Columbian Maya temple at Tantum Cuzamil.
