In Corinth, Dark is unable to be killed and is imprisoned in the facility. While Lana (Original blonde bratty girl) is working at the hospital, the two meet. Lana helps him escape, and he barely manages to escape. He infiltrates the city, infiltrates a noble family, and then Artius (Dark's Dragon dad) comes looking for him.
