Jade, the mysterious and magical substance once exclusive to the Green Bone warriors of Kekon, is now coveted throughout the world. Everyone wants access to the supernatural abilities it provides, from traditional forces such as governments, mercenaries, and criminal kingpins, to modern players, including doctors, athletes, and movie studios.

Powerful foreign governments and mercenary criminal kingpins alike turn their eyes on the island nation. Jade, Kekon's most prized resource, could make them rich - or give them the edge they'd need to topple their rivals.
