In Assassin's Creed IV: Black Flag, which body of water is the main setting?

The main setting of Assassin's Creed IV: Black Flag is the Caribbean Sea.

The game follows Edward Kenway, a Welsh privateer who becomes involved with both pirates and the Assassin–Templar conflict during the early eighteenth century. Its open world includes islands and ports across the Caribbean.

Major locations include Havana, Kingston, and Nassau. Naval travel is central to the game, with Edward commanding the ship Jackdaw and engaging in exploration, trading, and sea battles.

Black Flag is sometimes described simply as a pirate game, but its plot also connects directly to the wider Assassin's Creed mythology. Edward is the grandfather of Ratonhnhaké:ton, also known as Connor, the protagonist of Assassin's Creed III.
