Starkiller Base was a military base located on the ice planet of Ilum in the Unknown Regions. The base served as a stronghold of the First Order thirty years after the Battle of Endor. Commanded by an unofficial triumvirate of General Armitage Hux, Kylo Ren, and Captain Phasma, it was armed with a superweapon capable of destroying entire star systems halfway across the galaxy. The First Order viewed this ability as an evolution of the planet-destroying capabilities of the Galactic Empire's Death Star designs, with the weapon serving as the ultimate culmination of old Imperial research into dark energy translations and hyperspace tunneling. The base and planet were ultimately destroyed by a Resistance attack due to a weak point exploited by pilot Poe Dameron, causing the implosion of the entire planet as the superweapon was firing upon the Resistance base on D'Qar. The stored stellar energy then expanded, causing the planet to turn into a star.
