Upari
An Upari crystal Upari designates a kind of lightsaber crystal that one would often come across dispersed around the orbit of forested planets. While fragile, it was adaptable, allowing a Jedi Master to coax a wide range of results from it. On Kashyyyk, a Wookiee tribe possessed the capability to shape an Upari stone into ornamental jewels. This shaping process modified the properties of the crystal, enhancing its power.
