Have you ever heard of the deep, blue Gravity Seas? It's not on any maps, and most people have never heard of it. Some people think it's a myth. But if you're curious, don't wait. Tales of mystery and adventure lure into the ocean that none will dare to step into, except for one pirate crew: The Nightmare Dwellers.
