1: This universe is built around energy called: Ambient Energy, which can exist naturally as a solid, liquid, or gas. Supposedly it can be harnessed in it's solid state but beware, in it's solid form it can explode, in it's liquid form it can crystallize objects, as a gas it can pull things apart and shock them. This Energy can be found on the planet Heart in a solid form and exists in the outer atmosphere in it's gas form.
