Ilum

Ilum was a snow-covered planet located in the 7G sector of the Unknown Regions, within the Ilum system. Ilum had a kyber crystalline core, and had been utilized by the Jedi Order for the Gathering, a rite of passage in which Jedi younglings had to find and harvest kyber crystals for their lightsabers, which had existed for thousands of standard years. After the fall of the Empire, its successor state, the First Order, converted the massive trench into Starkiller Base.

First Order Stormtrooper

Stormtroopers, also known as First Order stormtroopers or "bucketheads," were the infantry soldiers of the First Order. As the latest evolution of one of galactic history's most distinctive symbols of military might, the First Order's infantry units were outfitted with stark white armor derived from that worn by the Galactic Republic's clone troopers and the Galactic Empire's identically named elite shock troops.
