Flint is one of the main villains of Crystal Zenith - being a criminal on the run after causing a war that happened twelve years prior to the events of the story. He tends not to reveal much about his past unless necessary, leading him to be rather closed-off and secretive. He's calculating, but not entirely "evil" - he's complex, as he experiences regret and guilt like anybody else...but is able to put it aside for his one goal that he will stop at NOTHING to achieve - finishing what he started in the war...
