Back in the Mechanical Era, when material abundance led people to believe they were unique, no one ever imagined that fear would return in the not-so-distant future. The polar ice caps would melt, the seas would once again swallow the land, steel would eventually shatter, and technology would be lost. Humanity would return to the ocean once more. Then the waters would recede, new land would emerge, and fish would once again set foot on land, discovering new technologies all over again. Until the heat death of the universe, in this brand-new world, there would be nothing but endless darkness and suspicion. All things would eventually vanish; only change would endure. The Aquatic Age, a New Era.
