Buccaneer's Heart

The Buccaneer's Heart is a medallion that contains the souls of Blackbeard, Bartholomew Roberts, Henry Morgan, and Mary Reade. The ghosts will only appear when a pirate wears the medallion. Most people believed that the Buccaneer's Heart was only a myth.

However, Jack Sparrow found out that it was real and it was locked in the Port Royal treasury. Unfortunately, undead pirates stole it before he could get it. Jack managed to steal it back, but due to circumstances, Will Turner put it on first. With the help of the ghosts, Jack was able to defeat the undead pirates and leave them marooned.

In the end, the ghosts asked Will to be their captain, but Will smashed the Buccaneer's Heart, setting their spirits free.
