Ilum

Ilum was a snow-covered planet located in the 7G sector of the Unknown Regions, within the Ilum system. Ilum was the fifth planet from its parent star Asar, a blue dwarf, located roughly equidistant from Asar and the system's cometary cloud. Ilum had a kyber crystalline core, and had been utilized by the Jedi Order for the Gathering, a rite of passage in which Jedi younglings had to find and harvest kyber crystals for their lightsabers, which had existed for thousands of standard years.
