For as long as we have known there has only ever been the five senses. Some cases of being deaf, or blind, or other situations have caused senses to become void and stripped away from you. But then there are those who claim to have a sixth sense, since they know patterns and are used to repitition, unless you were born a sixth sense and your abilities are what is known as superpowers.
The only thing no one has ever realized is that there is also a seventh sense, with powers beyond any one sixth sense, or all of them combined. They are rare and hunted. If you are a seventh sense, your fate is sealed and you will be running for the rest of your life.
