The endless ocean and ferocious storms forever doom the Technicians to live a delicate existence somewhere between the tortuous winds above and the crushing depths below. They toil endlessly to shore up the perimeter of the wave-torn ancient structure they inhabit. For countless generations no one has seen anything more than brief glimpses of the chaotic 'topside'. Holding on to some parts of ancient technologies, the basic knowledge of where they came from and the nature of their world have long been forgotten. When their great floating city threatens to break apart, the Technician race must search for a place to colonize. Since no one has ever heard of 'anywhere else', where could they possibly go? As if the breakup of the city wasn't bad enough, the experts detect a mysterious object in the deep more massive than a hundred cities -- and it's passing beneath them. Twin brothers Ix and Mox set out on a journey to rediscover what their ancestors knew, a move that will either save the Technicians or destroy everything they've ever known.
