Hurikane
this planet, located well beyond the galactic rim, was a rocky world inhabited by a race of strange, insectile humanoids. These beings were seemingly made of rock, with much of their body consisting of a gray, stone-like material which was studded with purplish, crystalline structures. When Mace Windu was just a Padawan, his Master sent him on a solo mission to Hurikane to obtain crystals for the construction of Mace's lightsaber. While on Hurikane, Mace mistakenly injured one of the humanoids, forcing him off a cliff and shattering parts of his body. Ashamed of his actions, Windu drew deeply from the Force and helped to repair the being. In return for his generosity, the natives of Hurikane provided young Windu with several of their purple crystals to use in his lightsaber. These crystals gave Mace Windu's lightsaber its unusual purple blade.
