Jade

Jade, sometimes referred to as Bioenergetic Kekonese Jade (mainly by Espenian nationals), is a green mineral used by Green Bones to unleash powerful abilities.

Disciplines
There are six disciplines of Jade ability--Strength, Steel, Perception, Lightness, Deflection and Channelling--which each grant different abilities. Each discipline must be learned and trained profusely in.

Strength
This discipline enhances the physical power of the greenbone.

Steel
The primary physically defensive discipline. Steeling oneself makes a greenbone less susceptible to harm by strengthening the body.

Perception
Allows the greenbone to sense things outside of oneself,

Lightness
Improves agility and speed.

Deflection
Deflection creates a wall of force that blows away anything it comes into contact with.

Channelling
Channelling Jade aura out of the body can be used by greenbone physicians to heal (one of the hardest applications of Jade).

Trivia

 * Despite never being referred as such in the text, the Jade disciplines could be classified as a Hard Magic System.
