Which Caribbean region is the primary setting of Assassin's Creed IV: Black Flag?

The West Indies are the primary setting of Assassin's Creed IV: Black Flag. The game follows Welsh pirate Edward Kenway through the Caribbean during the Golden Age of Piracy in the early eighteenth century.

Its open world includes islands and cities such as Havana, Kingston, and Nassau. Edward becomes entangled in the conflict between Assassins and Templars while pursuing opportunities among pirates, privateers, and colonial powers.

Black Flag was released in 2013 and is especially known for naval exploration and ship combat aboard Edward's vessel, the Jackdaw. Players can attack forts, hunt sea creatures, gather resources, and travel between islands.

The game is sometimes described simply as a Caribbean adventure, but “West Indies” is the specific historical region used in the question. It is not set primarily in the Mediterranean, which is more closely associated with several earlier European entries.
