The Destiny Islands are featured in all three of the main Kingdom Hearts games, though playable only briefly in Kingdom Hearts and Kingdom Hearts: Chain of Memories. They form an original world created for the Kingdom Hearts series. Some of the main characters of the series reside here; Sora, Riku, Kairi. Other characters include Tidus, Wakka, and Selphie, which were originally Final Fantasy characters. The world is enveloped by the darkness in the beginning of Kingdom Hearts, but is restored after the sealing of the door to Kingdom Hearts at the end.
The islands are an archipelago that consists of several land masses. Close enough to the main islands to be reached by small boats is an island that several of the character visit for recreation. The keyhole of the islands is located here in a small cave which Riku discovered as a boy. The main island is a regular town with a school. A superstition of the island is the power of the paopu fruit which is said to bind together the destinies of any two people who share one.
