Line 2:
Most [[Magitech]] and machines require some kind of [[Power Source]]. Common sources are coal, steam, electricity, or even [[Phlebotinum]]. But sometimes, that source is something which is biological and alive, sometimes even sentient. It's a '''Living Battery''', which the machine or device takes the [[Life Energy]] from almost parasitically.
 
We generally don't feel too bad if such living batteries are plants or insects, but the more intelligent, humanoid and sentient the creature, the more likely this will be [[Played for Drama]]. The story may reveal the battery is being taken advantage of, if not outright enslaved, and the extraction of the '''Living Battery''''s energy is harmful, traumatizing, or even lethal. Often the justification for why it is necessary is some form of Higher-Species-Rights, [[Fantastic Racism]], the fact that the parasitic species created the '''Living Battery''' in the first place, or simple desperation and need on the part of the extracting species. Or the extractors might just be [[Villain]]s who don't care who they hurt in the name of gaining power.
 
A [[Sub-Trope]] of [[Power Source]]. [[Powered by a Forsaken Child]] is itself a subtrope. Compare [[Life Energy]], [[Sentient Phlebotinum]], [[Human Resources]] and [[Cast from Hit Points]].
