Since Void is aspect of Junk (things that are considered no longer usefull), it means that Maid of Void might be that one person who makes various machines and other stuff from things they have recovered in junkyard. Like that guy who had made motocycle from metal scraps and recovered bits of various models.

I mean that’s an interesting thought, of Void = Junk, but.

Danny Devito as the Maid of Void? Trashman abound.
