The story, as told by Jack Sparrow, begins in Singapore at Cheng's Castle. Two servant girls, Shan and Jing, walk down a heavily guarded corridor in the castle. They enter an empty room and unlock a wall to be greeted by Jack. He takes a Dragon Tile to unleash a booby trap. He escapes by jumping off a huge cliff into the water below into the clutches of the Sea Guard, a group of humanoid sea monsters who reside as guardians of the tile.
