Kayn was brought up to be a perfect, almost mechanically-flawless performer, who rebelled against that training when he joined a band prior to HEARTSTEEL. Kayn is perfect, precise and sharp. He joined HEARTSTEEL as a way to spite his old band and let out his alter ego, Rhaast. Rhaast is messy, Rhaast is reckless, Rhaast is unapologetically emotional and angry and in your face, and won't let you forget it.
