Enligt filmens officiella novellering kanaliseras den "mörka energin" från den lokala stjärnan in i gigantiska " samlare " på baksidan av Starkiller Base-planet. Den lagras inuti kärnan och avfyrades sedan genom den stora pistolen på framsidan:
Having been gathered in stages by an immense array of coupled collectors located on the other side of the planet, a tremendously compact volume of a type of dark energy known as quintessence had been accumulated at the center of the planet. Held in place inside a roiling molten metal core by the frozen world’s powerful magnetic field, augmented by the weapons system’s own containment field, it grew until there was nothing like it—nothing natural like it—in this corner of the galaxy.
