The mountainous ice planet Ilum is home to one of the Jedi Order's most distant outposts. Nestled between snow-covered crags is an enclave used by the Jedi for generations, a shelter from the cold and a launching point for journeys into Ilum's exotic crystal caves. These caves produce some of the most rare and powerful lightsaber crystals in the galaxy.
Ilum hosts no indigenous population, although a number of larger animals survive in its environment. Its temperatures fail to reach the extremes of Hoth, but it has never been a target for colonization or occupation.
