Together, Calla and her five companions had defeated many tremendous foes. They persevered to bring peace to the people, and battled against a shadowy organization which acted only to serve its own ends. Calla's clan infiltrated their main headquarters, where they exposed the evil assembly's wrongdoings and brought them to an end. They were extolled as the "Six Heroes", as they had fought not for fame or fortune, but to be a beacon of hope for others.
