What is Ilum? Ilum is a planet weâve seen before in The Clone Wars. Like Starkiller Base, it is a snow-covered planet, but it is also a planet of great importance to the Jedi. Before the rise of the Empire, the Jedi harvested kyber crystals from Ilum to be used in their lightsabers.
[Source] A Jedi was a Force-sensitive individual, most often a member of the Jedi Order, who studied, served, and used the mystical energies of the Force; usually, the light side of the Force. The weapon of a Jedi was the lightsaber, a blade made of pure energy. Jedi fought for peace and justice in the Galactic Republic, usually against their mortal enemy: the Sith, who studied the dark side of the Force. The Jedi were of ancient origins, having been present in the galaxy for over one thousand generations. There were ten thousand Jedi in the galaxy before the Clone Wars.
