Myriad Miles Rivers and Mountains Painting

A mysterious and powerful ancient artifact. The painting is on a scroll and depicts a spacious land that had distant mountains with a river flowing in between. The four ancient letters of its name, Myriad Miles Rivers and Mountains, are also written on it. The power and abilities it holds have been bound by layers of complex Runic Patterns, with the outer most being the Myriad Spiritual Lock. If anyone tried to open the Myriad Spiritual Lock, it will stir up the rebound energy from those sealing inscription patterns behind, causing a large backlash.
