Energy core

Energy Cores are devices consisting of four Energy projector's in the shape of a three-sided pyramid that project streams of energy into its hollow center. The three streams combine to form a ball of energy that is maintained in stasis. The purpose of these devices is unknown, although they could be a battery-type energy source. They are highly explosive (four times the power of any other explosion alone) if moved or touched violently. They are found in Forerunner stations, such as the Halos and maybe Gas mines.
