Does it have symbols?

The Kiel Gnomenfoot Books symbolize the alternate reality that readers find with their favorite characters, sometimes especially when set in fictional and fantastic worlds. Owen is heavily invested in the books and jumps at the chance to take Kiel's place in the action.

Kiel's heart symbolizes the final key to opening the vault, but only if he gives it selflessly. Owen is in Kiel's place at that point in the book, and he tricks Dr. Verity into a plan that makes the heart useless.

The First Magician symbolizes the connection between science and magic and the fact that the two civilizations were once a single community. The First Magician also serves as a means for the author to relate more details of the story.
