Chakra Diamonds

Chakra Diamonds are an unexplained phenomenon. These diamonds have vast amounts of condensed chakra store within. An individual can tap into said chakra by making physical contact with the diamond and casting a jutsu. Although thought to be only items of legend, Hādo Iwa discovers that they are indeed real while exploring the Diamond Caverns. Shortly after, Hādo also discovers that he is not the only one who knows of their existence.
