At the heart of every Jedi lightsaber is a kyber crystal found on several planets, most notably the icebound caves of Ilum. This crystal is attuned to the Force, and connected to a Jedi Knight on a deeply personal level. In this way, a lightsaber is an extension of a Jedi's Force awareness. Because Jedi let the Force guide their selection of the crystal, the vibration that the crystal creates in the lightsaber blade helps Jedi center themselves and find balance in the Force. In this way, a Jedi can center his or her attention beyond the distractions of combat. A lightsaber crystal is colorless until first attuned and connected to a Jedi -- at which times it glows either blue or green, or in some rare instances, another shade. From that point on, it retains that hue.
A starry-eyed Rodian girl, Ganodi was a bright student in the Jedi Temple during the Clone Wars. She underwent an important rite of passage called The Gathering, which required her to enter the heart of the Crystal Cave on Ilum, and discover the crystal that was perfectly attuned to her through the Force. This gem would become the heart of her lightsaber, but first, she needed to overcome despair at the overwhelming nature of the challenge before her.
