Astra City was a technological 40th century masterpiece. It represented the challenge of society to the raw untamed planet where it raised its gleaming towers in a far-flung corner of the galaxy. Beyond the force field encircling Astra City lay mystery and terror in the form of the weird primeval Greek beasts.
There were other mysteries surrounding Astra City. Mysteries like those the one-eyed Twen discovered in the labyrinth below the modern city. A labyrinth whose age would only be calculated in centuries… but which was believed to have been erected by the distant Masters themselves. Hidden in its depths Twen discovers a forbidden document of the millennial age, which involves her with a secret society who know the dreadful truth about the colonists. They are Androids… and their dawning intelligence leads them into head-on conflict with the rapidly decaying human race.
