Jaz

Jaz Spin-off Series
Jaz is a nerdy kid, who is blind in the first book, that becomes the Realm Guardian of Earth. His father is Aaron, though his father only went to the Radiant Realm in Reality Five ( Jaz: The Fifth Reality ), which means Luxria is only his mother in Reality Five.

In the first book, Jaz is blinded in a fire that kills his family, and only survived thanks to his best friend Jack. Jack, however, is burned on the left eye. Jack hides the burn from him, though. Jaz has another best-friend named Jewel, who harbors a well hidden crush for him. Jaz and Jewel create a serum that allows the user to transform into a creature they think up at will. It somehow works, though not through science as they think.
