In Assassin's Creed IV: Black Flag, the Welsh pirate who becomes the protagonist is Edward Kenway.
Edward begins the game as a privateer and pirate operating during the Golden Age of Piracy in the early eighteenth century. Although he initially pursues wealth and status, his involvement with the Assassins and Templars gradually changes his priorities. The game follows his activities across the Caribbean, including Nassau, Havana, and Kingston.
Edward is the father of Haytham Kenway and the grandfather of Ratonhnhaké:ton, also known as Connor, the protagonist of Assassin's Creed III. This makes him part of the Kenway family storyline that links several games. A common mix-up is to answer Haytham, because he is also a major Kenway character, but Haytham is Edward's son and appears prominently in Assassin's Creed III.
