One lovely design was randomly directed labyrinths. Every member of this godlike super-species could make as many as they wanted, but one stood out as a particular sadist who filled his with victims. Knowing full well the hatred nobler entities had for him, he needed immense protection, so he sought out servants and allies, grooming beast machines to guard his lairs. He went back in time and was the Devil's impostor.
