Thanks to its importance in various real-world belief systems, jade is often assigned a mystical, spiritual, or otherwise supernatural function in fiction.
In China, objects crafted from jade were traditionally the status symbol, higher than gold and diamond. As a material, it has been attributed with many supernatural properties, including the ability to absorb negative energies. Jade ornaments were believed to grow alongside the wearer, enriching both over time. Similarly, smoking through jade pipes was believed to grant longevity, and nobility are known to have been buried in jade suits to take advantage of its protective properties. Jade also carries a heavy influence in Chinese Mythology, specifically the Jade Emperor who rules over the Heavenly bureaucracy.
Jade also had a significant role in the cultures of Central America, particularly the Maya, who associated it with death, the sun, and nobility. In Māori culture, jade and other green stones are called pounamu and considered generational treasures.
Mystical Jade can draw on any of these mythologies and beliefs for its abilities, but can just as often have original functions, associations, and abilities. They might emit Emerald Power.

The aboleths, fishlike monsters and some of the munavris' most bitter enemies, are unwilling or unable to come close to them, and it's believed that the islands' influence played a part in the development of the munavris' Psychic Powers. The jade is tough enough for the munavris to make armor out of it, and each island is made up of a unique color of jade, which their inhabitants use as badge of their island of origin.
