Ghost Story Island

Some years ago, an island sank when something suddenly broke its only pipe. The sunken island caused a whirlpool which capsized a small crew of pirates delivering a shipment of patchflower to a western island called Haze.

The crew of the Retriever has explored both physical and ghostly versions of the remains of this sunken island. Nami has the island's damaged heart, a flat, cracked piece of glassy stone about the size of a human palm.
