There were 13 armies of different colors on Earth, representing 13 different types of powers.
As long as a person put on the ring, they would be able to activate the energy in the ring and perform all kinds of unbelievable abilities. The most common ability was the ability to materialize things.
Additionally, in order to put on the ring, one needed to have the right to do so. The right was dependent on the person's nature. It was only when the nature of the ring and the person matched that they would then be able to put on the ring and activate the energy within it.
