An empty white stone city, called Balycon, on the sea floor calls Archer to explore. He wants to live in the beautiful city but permission is denied because a crystal ball releases a deadly aura that traps its victims in a happy place and makes them oblivious to the dangers around them. After Archer is told he can live in the city if he makes it safe, he immediately plans to find a way. How difficult can it be to move a crystal ball away from the city? Certain he can eliminate a danger that's existed for centuries, Archer rapidly discovers he needs all the help he can get to survive the obstacles that lie ahead.
