The Mighty Murdina

In the next several centuries, a huge storm comes. It floods all the continents to the point where all land is underwater. Much of the population died. The population grew to a few billion and now humans have to live on ships and boats. The only place humans can survive in is where Australia used to be. Since there are billions of humans and not enough space, it's survival of the fittest. Humans team up to conquer other teams and live. This story follows one team, Sea Masters, and their captain; Murdina.
