Before the enfeebled of the dull-eyed lychnobite of the press could succumb to its influence, the cheerful voice of the magician awoke him.
Where it comes from
From Ancient Greek λυχνόβιος (lukhnóbios, “living by lamplight”), from λύχνος (lúkhnos, “lamp”) + βίος (bíos, “life”); ending analogical to cenobite.
