The Devil's Due: Artifacts of the Black Freighter

From publisher blurb:

PIRATE NATIONS gives a few examples of ‘rewards’ for those willing to sacrifice flesh and soul to the Devil Jonah. However, some GMs may wish to have a plethora of options to tempt their players further down the path of damnation. The Devil Jonah freely gives these to those brave or foolish enough to offer themselves willingly. After all, even the bravest Heroes can only give so much before they fall to Villainy. Inside is a list of sample artifacts, plus a short guide to creating your own dark relics to seduce your Heroes into sacrificing their very souls with. The Black Freighter awaits you!
