Crystal Caves

The Crystal Caves of Ilum were a legendary pilgrimage site for the Jedi Order. Located deep beneath the surface of the planet Ilum, the colossal network of caverns stretched untold kilometers into the planet and contained a wealth of precious crystals which were vital to the construction of the Order's lightsabers. To guard against the possibility of the caves being plundered by outsiders, the Jedi erected a temple at the mouth of the cave system, Ilum's caves became a traditional journey point for many Jedi over the centuries.
