The Earthmover was a machine that was designed as a last resort to end the war against humanity, they are gargantuan in size, big enough to level a city in mere moments leaving nothing but ash and flames in it’s way and as a result are required to use both blood and solar power as a power source. They cannot be physically attacked from the outside making them practically impenetrable to anyone who dared approach them but despite this they can be destroyed from an internal assault.
