The most sacred world to the Jedi Order, the ancient planet Ilum is forever encased in ice, and whipped by biting winds. Hidden beneath the frozen surface is a Jedi Temple from the very dawn of the Order. It is here, within the legendary Crystal Caves, that Jedi initiates must undergo The Gathering. The rite of passage, handed down over centuries, requires Jedi younglings to trust their instincts, overcome inner obstacles, and find the unique Ilum crystal that is attuned to their Force presence. Upon retrieving the crystal, a Jedi initiate begins the process of constructing his or her lightsaber, under the guidance of Professor Huyang.
