Maketes has always been the jokester. No one takes him seriously, and if they do, it's only because he was born violent. But then he starts talking with a human through droids, and he finds a kindred spirit in them. When he's given an opportunity to find out who this human really is, he takes it.
But what he finds in that prison city is not just the person he was friends with. He finds a villainous group of people who wish to use him to their advantage, and a woman who captivates his entire soul.
Together, they travel throughout the remains of Gamma, a city long forgotten. And while they search for a key that will change how they see the entire world underneath the ocean, they find themselves growing closer. Soon enough, they realize that perhaps hiding their entire lives has prevented them from experiencing the greatest part of life.
