The Auryn also appears on the copper-colored cover of the book Bastian reads. In the movie The Neverending Story, the Auryn is able to grant Bastian’s wishes by channeling the powers of the Childlike Empress, who rules a world comprised of human imaginings, Fantastica.

On the back of the Auryn are these words: “Do what you Wish” (German: “Tu, was du willst”). In the book there is a portal ringed by the two snakes, one shining brighter than white, the other darker than black, that contains a waterfall and a pool called the Waters of Life, the gate between Fantastica (known as Fantasia in the movies and Phantásien in the original German novel) and our world. Anyone who wears the Auryn pendant is recognized as a messenger of the Childlike Empress.

Some sort of key to open a “portal to another world” certainly seems possible, and the way that one iDOL disappeared and then came back, it’s already been implied that something like going to another world has already happened.
