Hurrikaine crystals were deep blue to violet lightsaber crystals from the planet Hurikane admired for their unparalleled beauty. When used in lightsabers, they created blades that were very good at penetrating defenses. In 58 BBY, a young Mace Windu was sent to Hurikane on a mission as a Padawan. In exchange for helping the stone-encrusted native species, Windu was given a handful of the rare violet Hurrikane crystals, which he used to create his unique electrum lightsaber. The Windu's Guile crystal was later named in honor of the Jedi Master.
