Welcome to the Golden Age of Piracy. The year is 1715. Pirates rule the Caribbean and have established their own lawless Republic where corruption, greediness and cruelty are commonplace.

Among these outlaws is a brash young captain named Edward Kenway. His fight for glory has earned him the respect of legends like Blackbeard, but also drawn him into the ancient war between Assassins and Templars, a war that may destroy everything the pirates have built.
