Realm of Darkness

The Realm of Darkness is one of the primary locations of the Kingdom Hearts video game series. A world engulfed in total darkness detached from the other worlds, the Realm of Darkness is the home of the dangerous Heartless, where they appear in various forms and numbers, though most powerful in those occasions. It appeared as a form of challenge and imprisonment for heroes who enter the realm, including Aqua and Mickey Mouse. The Realm of Darkness also appears in the second Disney Heroes vs. Villains as the temporay confined place of heroes like Mr. Incredible before their rescue from benevolent sorcerers like Yen Sid.
