What natural phenomenon inspired the Metal Monster's abilities?

The Metal Monster's abilities are deeply connected to natural electromagnetic and gravitational forces[1]. The Metal People are described as 'animate, moving, sentient combinations of metal and electric energy'[1], with their 'blood' being lightning and their strength drawn from the sun[1]. Their movement is likened to a 'conscious breaking of the gravitational current'[1].

The text highlights their interaction with phenomena such as the aurora, which they 'suck down'[1], and their feeding on the sun, specifically a 'great sun spot'[1]. One character also theorizes that the earth's 'magnetic currents' feed these Metal Things[1].
