You know how you see something out of the corner of your eye but when you look there's nothing there? Well that's what this world is. It's a world that's hidden but can be found by certain people. These people are called Perceptors. They have powers, powers that make them stronger than any human or human made machine. Their task is to protect the secret of these worlds and find others of their kind. But this job does not come without difficulties. There are people who are after the Perceptors. Well not really people, more like creations of a mad man who wants power over the world. These mutants are called Retrievers and they are the only thing that can possibly defeat the Perceptors. Follow the story of ten kids. Who all have a different story, a different past.
