Corridors of Darkness

Corridors of Darkness are pathways of darkness that link the worlds of the Kingdom Hearts universe together. The Heartless use these extensively to reach other worlds, though they are not exclusive to them alone. Organization XIII utilizes these pathways, suggesting that though they are Nobodies, they still have access to the darkness. Other characters who have used these corridors include Diz, Riku, Kairi, Pluto and possibly King Mickey, though it appears that one must have a strong heart to resist the overwhelming darkness.

These corridors were seen in Kingdom Hearts but never referred to in name
