Dark energy

Dark energy, an energy type that filled the universe completely, dwarfed all other cosmic constituents in quantity, yet its dispersed nature made detection a challenge. The notion of harnessing dark energy for power was deemed unfeasible until the First Order achieved a breakthrough in gathering a specific type called quintessence. This technique enabled the construction of the Starkiller Base superweapon, possessing the destructive capacity to obliterate entire star systems.
