Years have passed since the apocalypse happened on the humans on land. Continuous corruption, pollution, plagues, wars, drought, and selfish yearnings resulted in the creation of the Zeroes, a race of humans that have lifeless emotions but have the desire to kill and destroy. Bringing nearly all living species on land to extinction was not enough and the Zeroes decided to have war with the sea. A Zero by the name of Teyron was the first zero to feel again and sacrificed himself to save a baby Cephalopods, an ancient giant octopus that rules and protects the sea. In return the King of the sea saved Teyron's son by connecting his lifeline with the baby Cephalopods giving him the power to live under the sea and be the first human ruler of all seas. This bond created a shield that separated the land and sea in order to protect those that live underwater. The great war ended with some Zeroes started to feel once more and decided to join forces with those living underwater to become the Perciles that vowed to protect the seas from the ruthless Zeroes who decided to feel only hate and anger. Teyron's son continued to pass on the royal bond through generations of first-borns that are descendants of Teyron and ruled alongside the guard of the Perciles until the Zeroes decided it was time to start war once more.
