The story is centered upon Jack Wolfbane, a 15-year-old boy led (with his best friend Hunter The Dog) by an enchanted map to a treehouse nicknamed the Tree Fort, which moves them into an "Outer Dimension Fantasy World" threatened by Lord Petreigus. They are now there to protect the story's eponymous dimension. To defeat Petreigus, Jack must find all the pieces of a key that will unlock the sealed gates to the kingdom of Bayvard, one of many realms comprising the dimension. And he must face against The Evil and Powerful King and a Energized Dragon.
