Starkiller Base

Starkiller Base, also called "the Starkiller," was a base located on the forested ice planet of Ilum rich in kyber crystals that was located in the Unknown Regions. The First Order, a regime that believed themselves to be the successors to the ideals of the Galactic Empire, converted the planet into a base of operations owing to its unique energy-transmitting crystalline deposits, and used it to house a superweapon capable of destroying entire star systems. The superweapon consumed suns as a power source. Its mobility was provided by rocket ports.
