In April 1981, Prof. Michael Lockwood was pulled into a mirror world by a mysterious light that became the Pisces Pendant. After his rescue, he built a research station near Pisces Town but triggered the Mirror Men incident, vanishing with his mirror double and leaving one deranged survivor. 26 years later, Corvus Niven investigates murders with DreamBridge and witnesses mirror men in action, forcing him to reopen the long-sealed case.
