A mysterious, otherworldly girl, cloaked in a mystical aura, reacts to his plea. Her eyes ablaze with fiery intensity, she commands his surrender. "Submit, demon!" In that moment, an unfamiliar warmth surges within him, and a glance behind reveals the emergence of ebony wings. He comes to the realization that he has transformed into a demon, now a captive of the elven tribe.
