Hurikane

Hurikane was a planet located in Wild Space. It was inhabited by a species of sentient beings made of stone and purple Hurrikaine crystals, who were almost insectoid in appearance.

In 58 BBY, a young Padawan named Mace Windu was sent to Hurikane to negotiate with these beings and possibly obtain some of the crystals. After events went poorly, several of the natives gave chase to Windu. During the chase, one of his pursuers fell into a canyon and was shattered. Having realized the error of his ways, the young Jedi apprentice healed the being's broken body by piecing it back together with the Force. In gratitude, Mace was given some of the Hurrikaine crystals from the being's own body, which he used to create his purple lightsaber blade.
