Hollow Bastion is a world from Kingdom Hearts and Kingdom Hearts II. Not based on a Disney film, though showing Disney influence, Hollow Bastion is a colossal castle that towers above the rest of its world, the Radiant Garden. At one point, it was the only remaining part of the world, along with the waterways beneath it.

Pete comes to the Timeless River as part of a wish to return to simpler days, which Maleficent takes advantage of and works into her plans. Heartless invade the sacred land and capture the Cornerstone of Light. This is because the Disney Castle of the future wouldn't have any way to protect itself leaving it vulnerable to the Heartless.
