Forsaken by the Empire After Ten Years at the Demon Cave

Harvey spent ten years sealing the Demon Cave as the lone Martial King keeping its darkness contained. When Empress Phoenix believes a slanderous report against him, she publicly strips him of his rank and leaves him disgraced. Then the seal shatters, three demon lords break free and tear through the Rosefinch Empire, and the court brands Harvey the culprit and sends soldiers after him. As the empire crumbles around him, Harvey refuses to step back into the fight, until the Demon Emperor's arrival threatens his sister Yvette and Empress Phoenix pleads for his help.
