In 19 pages of action-packed content, art, and battlemaps, the final chapter in the Rise of the Black Skull trilogy has the adventurers making their way to an island fortress controlled by the Black Skull Brotherhood. They're building an undead army and need to be stopped before reaching Hopewell Harbor. With the help of the crew of the Surprise, they must battle their way over the sea and take down the necromancers.
