In the middle of the 22nd century, raw materials on earth became increasingly scarce and as the end of the resources loomed, people began to prospect for resources on the ocean floor. This resulted in the construction of mining stations beneath the Pacific, Atlantic and Indian oceans. Many countries set up these deep-sea stations where workers and engineers extracted the oceans' treasures. Nevertheless, the output was far from enough to cover an ever-increasing demand. When the natural resources on Earth's surface were depleted, a time of destruction and wars began. In the fight over the planet's last remaining resources, alliances fell apart, countries became hostile and old conflicts flared up.
