History
Ilum was first discovered in 22,800 BBY when a Jedi, navigating hyperspace in the Force, felt a strong pull deep from the Unknown Regions. Following the sensation, the scout had found a world rich in Force-strong crystals. The mystique of the discovery added it to the ceremony of lightsaber construction.
Establishing a Temple over the Crystal Caves, Ilum became a place of great importance, as sacred as Ossus and Jedi who traveled here. To ensure the security of the planet and the crystals, the planet had been left off of starcharts. One uninterrupted hyperjump from Metellos would deliver a ship into Ilum’s orbit, and could only be accomplished by a Force-sensitive.
As part of his training, Anakin Skywalker, along with his mentor and friend Obi-Wan Kenobi also went there when he was young with his master Qui-Gon Jinn to build one of his first light sabers.
Because its existence was not known generally to non-Jedi, Ilum was virtually forgotten after the destruction of the Jedi and Palpatine’s information purges. This gave the remaining Jedi a safe harbor. After Order 66, Obi-Wan Kenobi received intelligence that his friend, Coruscant.
During the Empire’s hunt for Moff Kalast, who was leaking information to the Rebels, they discovered a Pirate base above Ilum, where Boba Fett (in the Slave I) tried to disable their sensors so an Imperial fleet could capture the Pirate Leader.
