The Crystal King - Monkie Kid AU

A Monkie Kid AU where Mayor and Syntax became heros (Syntax was revived) this is my third book and it might become my main, the Crystal King is one of my most favorite OCs, a Crystal King, the worst and strongest villain in history, lost to time itself as a myth, one day during an untimely pink moon, the Crystum Caverns that caused the King to be trapped in what he was created had one day collapsed, and the Crystal King, Chrystal was back in the world, but was he always bad? (Btw name is pronounced Christ-al Chrystal )
