The Mysterious Tower

The Tower is a place from Kingdom Hearts 2.

Towering atop the island floating above the skies of Twilight Town, the surrealistic, crooked tower that Sora encounters early in his adventure is owned by master Yen Sid. With twisted, eerie music in the background, the tower is truly a sight to behold against the twilight sky. On Sora's first journey up the tower, it is under attack by the Heartless. Later on, it is haunted by Nobodies.

It is possible that, due to the inclusion of the tower, Twilight Town is Fantasia's world. Whatever the case, the tower and its residents are obviously derived completely from the movie.

Trivia

 * During the time of the beta screenshots, the island holding the tower was known to many fans as the "Fabled Countryside."
