Dead Man's Chest

The Dead Man's Chest is a treasure chest, that holds inside the heart of Davy Jones, lord of the Flying Dutchman's ghost ship. Lost for centuries, prior to Jones' promise for immortality, the chest is later found by various characters, like Jack Sparrow or Cutler Beckett, knowing that, whoever obtains the Dead Man's Chest, controls Davy Jones and the Flying Dutchman. In other words, the wielder of the Dead Man's Chest controls the Seven Seas, and possibly the whole world.
