"Shocking and uncouth black things with smooth, oily, whale-like surfaces, unpleasant horns that curved inward toward each other, bat wings whose beating made no sound, ugly prehensile paws, and barbed tails that lashed needlessly and disquietingly. And worst of all, they never spoke or laughed, and never smiled because they had no faces at all to smile with, but only a suggestive blankness where a face ought to be. All they ever did was clutch and fly and tickle; that was the way of night-gaunts."
-H.P. Lovecraft, The Dream-Quest of Unknown Kadath
