The Nothing is a power which destroys whole Fantasia one by one by absorbing it. The Nothing gives people the desire to surrender themselves to oblivion by jumping into the nothing. Gmork said that the Nothing would be a chance for beings of Fantasia to come to the human world, but as lies. The Nothing was created by the manipulators, in fact it's the emptiness that remains when people stop to have phantasy. The Nothing succeeds in destroying Fantasia, however, Bastian creates a new version of it.
