The world of the Dark Keyblade Masters and their Apprentices, it is home to a seemingly endless horde of Heartless and Nobodies. The Heartless seem to spawn more here due to how close The World That Never Was is to the darkness of Kingdom Hearts. The Dark Keyblade Masters control the world from the Castle That Never Was, a massive fortress that floats weightlessly over the expansive Dark City. This World should not be entered by anyone under the level of a Keyblade Masters. There are far too many Heartless, Nobodies, and even Forgotten. Not to mention the presence of the Dark Keyblade Masters themselves. Even the Strongest fighters of the light do not dare enter here alone, and without good reason.
