wish key

The wish key is a magic golden key given to Michael by the Dungeon Master. It has one of two properties depending on the book's ending. If Michael chooses to remain in the Realm then the wish key will return him to his backyard whenever he wants to leave but if the Dungeon Master has returned Michael home then he can visit the Realm again using the wish key. In the latter scenario a note explains that the wish key will only work for one trip, whether this is a return trip or whether Michael will become stranded in the Realm should he choose to return is not clarified.
