Swordman Island

Swordman Island, also referred to as Swashbuckler's Island, is a world that appears in Kingdom Hearts V CAST. As Swordman Island only exists in Kingdom Hearts V CAST, it does not exist in Kingdom Hearts canon.

Setting
There is a kite puzzle that lifts you into a watchtower, a lava-filled chamber, and a mission where you must uncover four altar gems on a strange altar among the high rocks.

Story
Sora, Donald, Goofy, and Jiminy Cricket are traveling across the universe in the Gummi Ship when they decide to go to sleep. They put the Gummi Ship on autopilot, and in their sleep, a strange creature creeps undetected into the vessel and subsumes the dreams of Sora. When he wakes up, he is shipwrecked on a deserted island called Swordman Island, and Donald and Goofy are nowhere to be found. A parrot who helps you around the island. He says it would be a good idea to look around, so Sora explores the island. After searching he still cannot find Donald or Goofy, so the parrot says it would be wise to gather parts to make a raft and leave the island. Doing this requires you to explore the beaches, coves, and crags to get parts, much like in the beginning of Destiny Islands in Kingdom Hearts. After retrieving the four gems at the altar and finding all the parts to assemble the raft, Sora leaves the island and the chapter ends.
