Pirates: Cursed by Drake's Inferno

From publisher blurb: In this booklet are five individual Adventures set in the Caribbean. They can be played as isolated but profitable ventures, or as a series, but whatever the combination, they inevitably lead the party to a bonus Adventure. That final chapter will bind these tales together, for they have all been shadows of a ship, a phantom, Drake’s Inferno. What is the truth that leads to this legendary vessel? What are the tales of those who will thrice curse you before you can learn the truth? Where do they say to search? Requires the Pirates of the Caribbean sourcebook.
