Most people exist in four dimensions: depth, width, height and time. Those are some good dimensions to be sure. Nothing wrong with them. But some people, a select few, also exist in a fifth.
This fifth dimension isn't an alternate plane in reality, or the power of thought, or the home of an alien species known as the Kroolax. The fifth dimension is the reason why some people can sense things before they happen. The fifth dimension is what gives certain people almost supernatural speed and strength. When a mother lifts a car to free her trapped child, that's the fifth dimension.
It's a source of incredible power trapped in the human mind. Through the ages, it's been called many things. Chi. Telekinesis. Magic. It manifests in different ways for different people. For some, it manifests as an extreme charisma; a subtle power that draws people to them like moths to a flame, but without all the burning. These people usually become actors. The fifth dimension can be formed and used to manifest almost anything if you know what to do.
Some can create fire out of nothing. These people usually die from spontaneous self-combustion.
The fifth dimension is dangerous.
